Cell in Blazor DataGrid Component
27 Sep 202324 minutes to read
Displaying the HTML content
Displaying HTML content in a Grid can be useful in scenarios where you want to display formatted content, such as images, links, or tables, in a tabular format. Grid component allows you to display HTML tags in the Grid header and content. By default, the HTML content is encoded to prevent potential security vulnerabilities. However, you can enable the DisableHtmlEncode property by setting the value as false to display HTML tags without encoding. This feature is useful when you want to display HTML content in a grid cell.
In the following example, the Blazor Toggle Switch Button component is added to enable and disable the DisableHtmlEncode property. When the switch is toggled, the ValueChange event is triggered and the DisableHtmlEncode property of the column is updated accordingly. The Refresh method is called to Refresh the grid and display the updated content.

- The DisableHtmlEncode property disables HTML encoding for the corresponding column in the grid.
- If the property is set to true, any HTML tags in the column’s data will be displayed.
- If the property is set to false, the HTML tags will be removed and displayed as plain text.
- Disabling HTML encoding can potentially introduce security vulnerabilities, so use caution when enabling this feature.
Autowrap the grid content
The auto wrap feature allows the cell content in the grid to wrap to the next line when it exceeds the boundary of the specified cell width. The cell content wrapping works based on the position of white space between words. To support the Autowrap functionality in Syncfusion Grid, you should set the appropriate width for the columns. The column width defines the maximum width of a column and helps to wrap the content automatically.
To enable auto wrap, set the AllowTextWrap property to true. You can configure the auto wrap mode by setting the TextWrapSettings.WrapMode property.
Grid provides the below three options for configuring:
- Both - This is the default value for wrapMode. With this option, both the grid Header and Content text is wrapped.
- Header - With this option, only the grid header text is wrapped.
- Content - With this option, only the grid content is wrapped.
- When a column width is not specified, then auto wrap of columns will be adjusted with respect to the DataGrid’s width.
- If a column’s header text contains no white space, the text may not be wrapped.
- If the content of a cell contains HTML tags, the Autowrap functionality may not work as expected. In such cases, you can use the HeaderTemplate and Template features of the column to customize the appearance of the header and cell content.
The following example demonstrates how to set the AllowTextWrap property to true and specify the wrap mode as Content by setting the TextWrapSettings.WrapMode property.

}Customize cell styles
Customizing the grid cell styles allows you to modify the appearance of cells in the Grid control to meet your design requirements. You can customize the font, background color, and other styles of the cells. To customize the cell styles in the grid, you can use grid event, css or property support.
Using event
To customize the appearance of the grid cell, you can use the QueryCellInfo event of the grid. This event is triggered when each cell is rendered in the grid, and provides an object that contains information about the cell. You can use this object to modify the styles of the cell.
The following example demonstrates how to add a QueryCellInfo event handler to the grid. In the event handler, checked whether the current column is Freight field and then applied the appropriate CSS class to the cell based on its value.
@using Syncfusion.Blazor.Grids
@using BlazorApp1.Data
<SfGrid DataSource="@Orders" AllowSelection="false" EnableHover="false" Height="315">
<GridEvents QueryCellInfo="CustomizeCell" TValue="OrderData"></GridEvents>

<GridColumn Field=@nameof(OrderData.Freight) HeaderText="Freight" Format="C2" Width="100"></GridColumn>
<GridColumn Field=@nameof(OrderData.ShipCity) HeaderText="Ship City" Width="100"></GridColumn>
</GridColumns>
</SfGrid>
@code {
public List<OrderData> Orders { get; set; }
protected override void OnInitialized()
{
Orders = OrderData.GetAllRecords();
}
public void CustomizeCell(QueryCellInfoEventArgs<OrderData> args)
{
if (args.Column.Field == "Freight")
{
if (args.Data.Freight < 30)
{
args.Cell.AddClass(new string[] { "below-30" });
}
else if (args.Data.Freight < 80)
{
args.Cell.AddClass(new string[] { "below-80" });
}
else
{
args.Cell.AddClass(new string[] { "above-80" });
}
}
}
}
<style>

}
</style>public class OrderData
{
public static List<OrderData> Orders = new List<OrderData>();
public OrderData()
{
}
public OrderData(int? OrderID,string CustomerID,double? Freight,string ShipCity)
{
this.OrderID = OrderID;
this.CustomerID = CustomerID;
this.Freight = Freight;
this.ShipCity = ShipCity;
}
public static List<OrderData> GetAllRecords()
{
if (Orders.Count() == 0)
{
int code = 10;
for (int i = 1; i < 2; i++)
{
Orders.Add(new OrderData(10248, "VINET", 32.38, "Reims"));
Orders.Add(new OrderData(10249, "TOMSP", 11.61, "Münster"));
Orders.Add(new OrderData(10250, "HANAR", 65.83, "Rio de Janeiro"));
Orders.Add(new OrderData(10251, "VICTE", 41.34, "Lyon"));
Orders.Add(new OrderData(10252, "SUPRD", 51.30, "Charleroi"));

Orders.Add(new OrderData(10254, "CHOPS", 22.98, "Bern"));
Orders.Add(new OrderData(10255, "RICSU", 148.33, "Genève"));

}
}
return Orders;
}
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public double? Freight { get; set; }
public string ShipCity { get; set; }
}The QueryCellInfo event is triggered for every cell of the grid, so it may impact the performance of the grid whether used to modify a large number of cells.
Using CSS
You can apply styles to the cells using CSS selectors. The Grid provides a class name for each cell element, which you can use to apply styles to that specific cell or cells in a particular column. The e-rowcell class is used to style the row cells, and the e-selectionbackground class is used to change the background color of the selected row.
<style>
.e-grid td.e-cellselectionbackground {
background: #9ac5ee;
font-style: italic;
}
</style>The following example demonstrates how to customize the appearance of a specific row in the grid on selection using className.
@using Syncfusion.Blazor.Grids
@using BlazorApp1.Data
<SfGrid DataSource="@Orders" AllowSelection="true" AllowPaging="true">
<GridSelectionSettings CellSelectionMode="CellSelectionMode.Box" Mode="SelectionMode.Cell" Type="SelectionType.Multiple"></GridSelectionSettings>

public string CustomerID { get; set; }
public string ShipCity { get; set; }
public string ShipName { get; set; }
}Using property
To customize the style of grid cells, define CustomAttributes property to the GridColumn definition object. The CustomAttributes property takes an object with the name-value pair to customize the CSS properties for grid cells. You can also set multiple CSS properties to the custom class using the CustomAttributes property.
<style>
.custom-css {
background: #d7f0f4;
font-style: italic;
color:navy
}
</style>Here, setting the CustomAttributes property of the ShipCity column to an object that contains the CSS class ‘custom-css’. This CSS class will be applied to all the cells in the ShipCity column of the grid.
<GridColumn Field=@nameof(Order.ShipCity) HeaderText="Ship City" CustomAttributes="@(new Dictionary<string, object>(){ { "class", "custom-css" }})" Width="100"></GridColumn>The following example demonstrates how to customize the appearance of the OrderID and ShipCity columns using custom attributes.

}Custom attributes can be used to customize any cell in the grid, including header and footer cells.
Clip Mode
The clip mode feature is useful when you have a long text or content in a grid cell, which overflows the cell’s width or height. It provides options to display the overflow content by either truncating it, displaying an ellipsis or displaying an ellipsis with a tooltip. You can enable this feature by setting Columns.ClipMode property to one of the below available options.
There are three types of ClipMode available:
- Clip: Truncates the cell content when it overflows its area.
- Ellipsis: Displays ellipsis when the cell content overflows its area.
- EllipsisWithTooltip: Displays ellipsis when the cell content overflows its area, also it will display the tooltip while hover on ellipsis is applied. Also it will display the tooltip while hover on ellipsis is applied.
The following example demonstrates, how to set the ClipMode property for the Grid column .

- By default, Columns.ClipMode value is Ellipsis.
- If you set the width property of a column, the clip mode feature will be automatically applied to that column if the content exceeds the specified width.
- Be careful when using the Clip mode, as it may result in important information being cut off. It is generally recommended to use the Ellipsis or EllipsisWithTooltip modes instead.
Tooltip
The Syncfusion Grid allows you to display information about the grid columns to the user when they hover over them with the mouse.
Display custom tooltip for columns
The Grid provides a feature to display custom tooltips for its columns using the SfTooltip component. This allows you to provide additional information about the columns when the user hovers over them.
To enable custom tooltips for columns in the Grid,you can use the Column Template feature by rendering the components inside the template
This is demonstrated in the following sample code, where the tooltip for the FirstName column is rendered using Column Template.

}Grid lines
The GridLines in a grid are used to separate the cells with horizontal and vertical lines for better readability. You can enable the grid lines by setting the GridLines property to one of the following values:
| Modes | Actions |
|---|---|
| Both | Displays both the horizontal and vertical DataGrid lines. |
| None | No DataGrid lines are displayed. |
| Horizontal | Displays the horizontal DataGrid lines only. |
| Vertical | Displays the vertical DataGrid lines only. |
| Default | Displays DataGrid lines based on the theme. |
The following example demonstrates how to set the GridLines property based on changing the dropdown value using the ValueChange event of the DropDownList component.
