Row in Blazor DataGrid

30 May 202524 minutes to read

Each row typically represents a single record or item from a data source. Rows in the Syncfusion Blazor DataGrid are used to present data in a tabular format. Each row displays a set of values the fields of an individual data record. Rows allow users to interact with the data in the Grid. Users can select rows, edit cell values, perform sorting or filtering operations, and trigger events based on actions.

Customize row styles

Customizing the styles of rows in the Syncfusion Blazor DataGrid allows you to modify the appearance of rows to meet your design requirements. This feature is useful when you want to highlight certain rows or change the font style, background color, and other properties of the row to enhance the visual appeal of the Grid. To customize the row styles in the Grid, you can use CSS, properties, methods, or event support provided by the Grid.

Using event

You can customize the appearance of the rows by using the RowDataBound event. This event triggers for every row when it is bound to the data source. In the event handler, you can get the RowDataBoundEventArgs object, which contains details of the row. You can use this object to modify the row’s appearance, add custom elements, or perform any other customization.

Here’s an example of how you can use the RowDataBound event to customize the styles of rows based on the value of the Freight column. This example involves checking the value of the Freight column for each row and adding a CSS class to the row based on the value. The CSS classes below-30, below-80, and above-80 can then be defined in your stylesheet to apply the desired styles to the rows:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Orders">
    <GridEvents TValue="OrderData" RowDataBound="RowBound"></GridEvents>
    <GridColumns>
        <GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="100"></GridColumn>
        <GridColumn Field=@nameof(OrderData.CustomerID) HeaderText="Customer ID" Width="120"></GridColumn>
        <GridColumn Field=@nameof(OrderData.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="80"></GridColumn>
        <GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="ShipCity" Width="130"></GridColumn>
    </GridColumns>
</SfGrid>
<style>
    .below-30 {
        background-color: rgb(211, 225, 248);
    }
    .below-80 {
        background-color: rgb(163, 236, 217);
    }
    .above-80 {
        background-color: rgb(220, 248, 177);
    }
</style>

@code {
    private SfGrid<OrderData> Grid;
    public List<OrderData> Orders { get; set; }

    protected override void OnInitialized()
    {
        Orders = OrderData.GetAllRecords();
    }
    public void RowBound(RowDataBoundEventArgs<OrderData> args)
    {
        if (args.Data.Freight < 30)
        {
            args.Row.AddClass(new string[] { "below-30" });
        }
        else if (args.Data.Freight < 80)
        {
            args.Row.AddClass(new string[] { "below-80" });
        }
        else
        {
            args.Row.AddClass(new string[] { "above-80" });
        }
    }
}
public class OrderData

    public static List<OrderData> Orders = new List<OrderData>();

    public OrderData() { }

    public OrderData(int? OrderID, string CustomerID, double Freight, DateTime? OrderDate, DateTime? ShippedDate, bool? IsVerified, string ShipCity)
    {
        this.OrderID = OrderID;
        this.CustomerID = CustomerID;
        this.Freight = Freight;
        this.OrderDate = OrderDate;
        this.ShippedDate = ShippedDate;
        this.IsVerified = IsVerified;
        this.ShipCity = ShipCity;
    }

    public static List<OrderData> GetAllRecords()
    {
        if (Orders.Count == 0)
        {
            Orders.Add(new OrderData(10248, "VINET", 32.38, new DateTime(1996, 7, 4), new DateTime(1996, 08, 07), true, "Reims"));
            Orders.Add(new OrderData(10249, "TOMSP", 11.61, new DateTime(1996, 7, 5), new DateTime(1996, 08, 07), false, "Münster"));

    public double? Freight { get; set; }
    public DateTime? OrderDate { get; set; }
    public DateTime? ShippedDate { get; set; }
    public bool? IsVerified { get; set; }
    public string ShipCity { get; set; } 
}

The QueryCellInfo event can also be used to customize cells and is triggered for every cell in the Grid. It can be useful when you need to customize cells based on certain conditions or criteria.

Using CSS

You can apply styles to the rows using CSS selectors. The Syncfusion Blazor DataGrid provides a class name for each row element, which you can use to apply styles to that specific row.

Customize alternate rows

You can customize the appearance of the alternate rows using CSS. This can be useful for improving the readability of the data and making it easier to distinguish between rows. By default, Grid provides the CSS class .e-altrow to style the alternate rows. You can customize this default style by overriding the .e-altrow class with your custom CSS styles.

To change the background color of the alternate rows, you can add the following CSS code to your application’s stylesheet:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Orders">
    <GridColumns>
        <GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="100"></GridColumn>

        this.IsVerified = IsVerified;
        this.ShipCity = ShipCity;
    }

    public static List<OrderData> GetAllRecords()
    {
        if (Orders.Count == 0)
        {
            Orders.Add(new OrderData(10248, "VINET", 32.38, new DateTime(1996, 7, 4), new DateTime(1996, 08, 07), true, "Reims"));

Customize selected row

You can customize the appearance of the selected row using CSS. This is useful when you want to highlight the currently selected row for improve the visual appeal of the Grid. By default, the Grid provides the CSS class .e-selectionbackground to style the selected row. You can customize this default style by overriding the .e-selectionbackground class with your own custom CSS styles.

To change the background color of the selected row, you can add the following CSS code to your application:

#CustomGrid .e-selectionbackground {
    background-color: #f9920b;
}

Here’s an example of how to use the .e-selectionbackground class to style the selected row:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids

<SfGrid ID="CustomGrid" DataSource="@Orders">
    <GridColumns>
        <GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="100"></GridColumn>
        <GridColumn Field=@nameof(OrderData.CustomerID) HeaderText="Customer ID" Width="120"></GridColumn>
        <GridColumn Field=@nameof(OrderData.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="80"></GridColumn>
        <GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="ShipCity" Width="130"></GridColumn>
    </GridColumns>
</SfGrid>

<style>
    #CustomGrid .e-selectionbackground {
        background-color: #f9920b;
    }
</style>


@code {

        this.Freight = Freight;
        this.OrderDate = OrderDate;
        this.ShippedDate = ShippedDate;
        this.IsVerified = IsVerified;
        this.ShipCity = ShipCity;
    }

    public static List<OrderData> GetAllRecords()
    {
        if (Orders.Count == 0)
        {
            Orders.Add(new OrderData(10248, "VINET", 32.38, new DateTime(1996, 7, 4), new DateTime(1996, 08, 07), true, "Reims"));

Row height

The Syncfusion Blazor DataGrid allows you to customize the height of rows based on your needs. This feature can be useful when you need to display more content in a row or when you want to reduce the height of rows to fit its content. You can achieve this by using the RowHeight property of the Grid. This property allows you to change the height of the entire Grid row to your desired value.

In the below example, we will demonstrate how to dynamically change the height of the rows using the RowHeight property:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Buttons

<div>
    <SfButton class="e-btn e-small" @onclick="() => ChangeRowHeight(20)">Change height 20px</SfButton>
    <SfButton class="e-btn e-small" @onclick="() => ChangeRowHeight(42)">Default height 42px</SfButton>
    <SfButton class="e-btn e-small" @onclick="() => ChangeRowHeight(60)">Change height 60px</SfButton>
</div>

<div style="padding-top:20px">
    <SfGrid @ref="Grid" DataSource="@Orders" RowHeight="@RowHeightValue" Height="400">
        <GridColumns>
            <GridColumn Field="OrderID" HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
            <GridColumn Field="CustomerID" HeaderText="Customer Name" Width="150"></GridColumn>
            <GridColumn Field="OrderDate" HeaderText="Order Date" Width="130" Type="ColumnType.Date" Format="dd/MM/yyyy" TextAlign="TextAlign.Right"></GridColumn>
            <GridColumn Field="Freight" HeaderText="Freight" Width="120" Format="C2" TextAlign="TextAlign.Right"></GridColumn>
            <GridColumn Field="ShippedDate" HeaderText="Shipped Date" Width="140" Type="ColumnType.Date" Format="dd/MM/yyyy" TextAlign="TextAlign.Right"></GridColumn>
            <GridColumn Field="ShipCountry" HeaderText="Ship Country" Width="150"></GridColumn>
        </GridColumns>
    </SfGrid>
</div>

@code {
    private SfGrid<OrderData> Grid;
    public List<OrderData> Orders { get; set; }
    public int RowHeightValue { get; set; } = 42; // Default height.

    protected override void OnInitialized()
    {
        Orders = OrderData.GetAllRecords();
    }

    private void ChangeRowHeight(int height)
    {
        RowHeightValue = height;
        Grid.Refresh(); // Refresh the Grid to apply the new row height.
    }
}
public class OrderData
{
    public static List<OrderData> Orders = new List<OrderData>();

    public OrderData() { }

    public OrderData(int? OrderID, string CustomerID, string ShipName, double Freight, DateTime? OrderDate, DateTime? ShippedDate, bool? IsVerified, string ShipCity, string ShipCountry)
    {
        this.OrderID = OrderID;
        this.CustomerID = CustomerID;
        this.ShipName = ShipName;
        this.Freight = Freight;
        this.OrderDate = OrderDate;
        this.ShippedDate = ShippedDate;
        this.IsVerified = IsVerified;
        this.ShipCity = ShipCity;
        this.ShipCountry = ShipCountry;
    }

    public static List<OrderData> GetAllRecords()
    {
        if (Orders.Count == 0)
        {
            Orders.Add(new OrderData(10248, "VINET", "Vins et alcools Chevalier", 32.38, new DateTime(1996, 7, 4), new DateTime(1996, 08, 07), true, "Reims", "France"));

            Orders.Add(new OrderData(10250, "HANAR", "Hanari Carnes", 65.83, new DateTime(1996, 7, 6), new DateTime(1996, 08, 07), true, "Rio de Janeiro", "Brazil"));
            Orders.Add(new OrderData(10251, "VINET", "Vins et alcools Chevalier", 41.34, new DateTime(1996, 7, 7), new DateTime(1996, 08, 07), false, "Lyon", "France"));
            Orders.Add(new OrderData(10252, "SUPRD", "Suprêmes délices", 151.30, new DateTime(1996, 7, 8), new DateTime(1996, 08, 07), true, "Charleroi", "Belgium"));
            Orders.Add(new OrderData(10253, "HANAR", "Hanari Carnes", 58.17, new DateTime(1996, 7, 9), new DateTime(1996, 08, 07), false, "Bern", "Switzerland"));

            Orders.Add(new OrderData(10255, "VINET", "Vins et alcools Chevalier", 148.33, new DateTime(1996, 7, 11), new DateTime(1996, 08, 07), false, "Resende", "Brazil"));
            Orders.Add(new OrderData(10256, "HANAR", "Hanari Carnes", 13.97, new DateTime(1996, 7, 12), new DateTime(1996, 08, 07), true, "Paris", "France"));
        }
        return Orders;
    }

    public int? OrderID { get; set; }
    public string CustomerID { get; set; }
    public string ShipName { get; set; } 
    public double? Freight { get; set; }
    public DateTime? OrderDate { get; set; }
    public DateTime? ShippedDate { get; set; }
    public bool? IsVerified { get; set; }
    public string ShipCity { get; set; }
    public string ShipCountry { get; set; }
}

The RowHeight property can only be used to set the height of the entire Grid row. It cannot be used to set the height of individual cells within a row.
The RowHeight property applies the height to all rows in the Grid, including the header and footer rows.
You can also set the height for a specific row using the RowHeight property of the corresponding row object in the RowDataBound event.

Customize row height for particular row

Customizing the row height for a particular row can be useful when you want to display more content in a particular row, reduce the height of a row to fit its content, or make a specific row stand out from the other rows in the Grid. This can be achieved by using the RowHeight property of the Grid along with the RowDataBound event.

The RowHeight property of the Grid allows you to set the height of all rows in the Grid to a specific value. However, if you want to customize the row height for a specific row based on the row data, you can use the RowDataBound event. This event is triggered every time a request is made to access row information, element, or data, and before the row element is appended to the Grid element.

In the below example, the row height for the row with OrderID as ‘10249’ is set as ‘90px’ using the RowDataBound event.

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids

<SfGrid @ref="Grid" DataSource="@Orders" AllowSelection="true" Height="315px">
    <GridEvents TValue="OrderData" RowDataBound="RowBound"></GridEvents>

       <GridColumn Field=@nameof(OrderData.Freight) HeaderText="Freight" Width="80"></GridColumn>
        <GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="Ship City" Width="100"></GridColumn>

    </GridColumns>
</SfGrid>
<style>
    .row-height {
        height: 90px;
    }
</style>

@code {
    private SfGrid<OrderData> Grid;
    public List<OrderData> Orders { get; set; }
    public void RowBound(RowDataBoundEventArgs<OrderData> args)
    {
        if (args.Data.OrderID == 10249)
        {
            args.Row.AddClass(new string[] { "row-height" });
        }
    }
    protected override void OnInitialized()
    {
        Orders = OrderData.GetAllRecords();
    }
}
public class OrderData
{

Row hover

The Row Hover feature in the Syncfusion Blazor DataGrid provides a visual effect when the mouse pointer hovers over the rows, making it easy to highlight and identify the selected row. This feature can also improve the readability of data in the Grid. The row hover effect can be enabled or disabled using the EnableHover property of the Grid.

By default, the EnableHover property is set to true, which means that the row hovering effect is enabled. To disable the row hover effect, set the EnableHover property to false.

Here is an example that demonstrates how to enable/disable row hover based on the Switch:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Buttons

<div style="padding:20px">
    <label>Enable/Disable Row Hover</label>
    <SfSwitch @bind-Checked="isChecked" TChecked="bool"></SfSwitch>
</div>
<SfGrid @ref="Grid" DataSource="@Orders" Height="400" EnableHover="@isChecked">
    <GridColumns>
        <GridColumn Field="OrderID" HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
        <GridColumn Field="CustomerID" HeaderText="Customer Name" Width="150"></GridColumn>
        <GridColumn Field="ShipCity" HeaderText="Ship City" Width="150"></GridColumn>
        <GridColumn Field="ShipName" HeaderText="Ship Name" Width="150"></GridColumn>
    </GridColumns>
</SfGrid>

@code {
    private SfGrid<OrderData> Grid;
    public List<OrderData> Orders { get; set; }
    private bool isChecked = true;

    protected override void OnInitialized()
    {
        Orders = OrderData.GetAllRecords();
    }
}
public class OrderData

    public static List<OrderData> Orders = new List<OrderData>();

    public OrderData() { }

    public OrderData(int? OrderID, string CustomerID, string ShipName, double Freight, DateTime? OrderDate, DateTime? ShippedDate, bool? IsVerified, string ShipCity, string ShipCountry)
    {

        this.CustomerID = CustomerID;
        this.ShipName = ShipName;
        this.Freight = Freight;
        this.OrderDate = OrderDate;
        this.ShippedDate = ShippedDate;
        this.IsVerified = IsVerified;
        this.ShipCity = ShipCity;
        this.ShipCountry = ShipCountry;
    }

    public static List<OrderData> GetAllRecords()
    {
        if (Orders.Count == 0)
        {
            Orders.Add(new OrderData(10248, "VINET", "Vins et alcools Chevalier", 32.38, new DateTime(1996, 7, 4), new DateTime(1996, 08, 07), true, "Reims", "France"));

            Orders.Add(new OrderData(10251, "VINET", "Vins et alcools Chevalier", 41.34, new DateTime(1996, 7, 7), new DateTime(1996, 08, 07), false, "Lyon", "France"));

The enableHover property applies to the entire Grid, not individual rows or columns.

Row pinning (Frozen)

The Syncfusion Blazor DataGrid allows you to freeze rows to keep them visible while scrolling vertically through large datasets. This feature enhances the experience by maintaining important information within view at all times.

To know about frozen rows in Grid, you can check this video.

In the following example, the FrozenRows property is set to 2. This configuration freezes the top two rows of the Grid, and they will remain fixed in their positions while the rest of the Grid can be scrolled vertically:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Inputs
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Buttons

<div style="display: flex; align-items: center; padding-bottom: 20px;">
    <label style="padding-right: 10px; font-weight: bold;">Change the frozen rows:</label>
    <SfNumericTextBox @ref="NumericTextBox" TValue="int" Value="@NumericValue" Min="1" Max="5" Decimals="0"
    ValidateDecimalOnType="true" Width="150px">
    </SfNumericTextBox>
    <SfButton style="margin-left: 10px;" CssClass="e-primary" @onclick="FrozenRowsFn">
        Update Value
    </SfButton>
</div>

<SfGrid @ref="Grid" DataSource="@Orders" AllowSelection="false" EnableHover="false"
        FrozenRows="@NumericValue" Height="315px">
    <GridColumns>
        <GridColumn Field=@nameof(OrderData.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="90"></GridColumn>
        <GridColumn Field=@nameof(OrderData.CustomerID) HeaderText="Customer ID" Width="100"></GridColumn>

    public bool? IsVerified { get; set; }
    public string ShipCity { get; set; }
    public string ShipCountry { get; set; }
}

Frozen rows should not be set outside the Grid view port.
Frozen Grid will support row virtualization feature, which helps to improve the Grid performance while loading a large dataset.
The frozen feature is supported only for the rows that are visible in the current view.
You can use both FrozenColumns property and FrozenRows property in the same application.

Change default frozen rows line color

You can easily customize the frozen line background color of frozen rows in the Syncfusion Blazor DataGrid by applying custom CSS styles to the specific frozen row. This allows you to change the background color of frozen rows to match your application’s design and theme.

To change the default frozen rows line color, you can use the following CSS class:

.e-grid .e-frozenrow-border {
    background-color: rgb(5, 114, 47);
}

By applying this CSS class, you can set the background color of frozen rows to the specified RGB color. The following example demonstrates how to change the default frozen rows line color using CSS.

When a validation message is displayed in the frozen part (Left, Right, Fixed) of the table, scrolling is prevented until the validation message is cleared.

Limitations

Frozen row is not compatible with the Autofill feature.

Adding a new row programmatically

The Syncfusion Blazor DataGrid provides a way to add a new row to the Grid programmatically. This feature is useful when you want to add a new record to the Grid without having the manually enter data in the Grid.This can be done using the AddRecordAsync method of the Grid.

The AddRecordAsync method takes two parameters:

The data object representing the new row to be added
The index at which the new row should be inserted. If no index is specified, the new row will be added at the end of the Grid.

Here’s an example of how to add a new row using the AddRecordAsync method:

Index.razor
OrderData.cs
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Buttons

<div style="padding: 0px 0px 20px 0px">
    <SfButton CssClass="e-primary" @onclick="AddRow">Add New Row</SfButton>

    <GridColumns>
        <GridColumn Field="@nameof(OrderData.OrderID)" HeaderText="Order ID" TextAlign="TextAlign.Right" Width="100" IsPrimaryKey="true"></GridColumn>
        <GridColumn Field="@nameof(OrderData.CustomerID)" HeaderText="Customer ID" Width="120"></GridColumn>
        <GridColumn Field="@nameof(OrderData.ShipCity)" HeaderText="Ship City" Width="100"></GridColumn>
        <GridColumn Field="@nameof(OrderData.Freight)" HeaderText="Freight" TextAlign="TextAlign.Right" Format="C" Width="100"></GridColumn>

When working with remote data, it is impossible to add a new row between the existing rows.
If you want to add a new record to the beginning of the data source, you can pass 0 as the second parameter to the AddRecordAsync method.
If you do not specify an index, the new row will be added at the end of the Grid.

How to get the row data and element

The Syncfusion Blazor DataGrid provides several methods to retrieve row data and elements. This feature is useful when you need to access specific rows, perform custom operations, or manipulate the data displayed in the Grid.

GetRowIndexByPrimaryKey: The method allows you to retrieve the row index based on a specific primary key value or row data.

<SfButton id="GetRowIndexByPrimaryKey" @onclick="GetDataHandler">GetRowIndexByPrimaryKey</SfButton>
<SfGrid @ref="grid" DataSource="@Orders">
 ........
</SfGrid>
@code{
   SfGrid<Order> grid;
    private async Task GetDataHandler()
    {
        var rowIndex = await Grid.GetRowIndexByPrimaryKeyAsync(10250);  // pass primary key value here.
    }
}

GetSelectedRowIndexesAsync: This methods allows you to get the collection of selected row indexes.

<SfButton id="GetSelectedRowIndexes " @onclick="GetDataHandler">GetSelectedRowIndexes </SfButton>
<SfGrid @ref="grid" DataSource="@Orders">
 ........
</SfGrid>
@code{
   SfGrid<Order> grid;
   private async Task GetDataHandler()
   {
        var SelectedRowIndexes = await grid.GetSelectedRowIndexesAsync();  
   }
}

Master Detail DataGrid

The Syncfusion Blazor DataGrid has an option to visualize details of a record in another Grid in a master and detail manner. By clicking the master Grid row, the detail Grid will be populated with the corresponding data. This can be achieved as follows:

Using the RowSelected event of the Master Grid, get the selected record details. Based on these selected record details, filter the data using the Query property of the Detail Grid and bind the resultant data to the DataSource property of the Detail Grid.

In the following sample, click the row in the master Grid, which shows the details in another(detail) Grid.
