Displaying the HTML content
The HTML tags can be displayed in the DataGrid header and content by enabling the DisableHtmlEncode property.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" Height="315">
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="<span> Order ID </span>" DisableHtmlEncode="false" TextAlign="TextAlign.Right" Width="140"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="<span> Customer ID </span>" DisableHtmlEncode="true" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText="Order Date" Format="d" Type="ColumnType.Date" Width="100"></GridColumn>
<GridColumn Field=@nameof(Order.ShipCity) HeaderText="Ship City" Width="100"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "<span>ANANTR</span>", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCity = (new string[] { "Seattle", "Tacoma", "Redmond", "Kirkland", "London" })[new Random().Next(5)],
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public string ShipCity { get; set; }
}
}The following screenshot represents a DataGrid displaying the HTML content.
Customize cell styles
The appearance of cells can be customized by using the QueryCellInfo event. The QueryCellInfo event triggers for every cell. In that event handler, you can get QueryCellInfoEventArgs that contains the details of the cell.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" AllowSelection="false" EnableHover="false" Height="315">
<GridEvents QueryCellInfo="CustomizeCell" TValue="Order"></GridEvents>
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="140"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer ID" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText="Order Date" Format="d" Type="ColumnType.Date" Width="140"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" Width="100"></GridColumn>
<GridColumn Field=@nameof(Order.ShipCity) HeaderText="Ship City" Width="100"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCity = (new string[] { "Seattle", "Tacoma", "Redmond", "Kirkland", "London" })[new Random().Next(5)],
OrderDate = DateTime.Now.AddDays(-x),
Freight = 6.2 * x,
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
public string ShipCity { get; set; }
}
public void CustomizeCell(QueryCellInfoEventArgs<Order> 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>
.below-30 {
background-color: orangered;
}
.below-80 {
background-color: yellow;
}
.above-80 {
background-color: greenyellow
}
</style>The following screenshot represents a DataGrid with customized cell styles.
Auto wrap
The auto wrap allows the cell content of the DataGrid to wrap to the next line when it exceeds the boundary of the cell width. The Cell Content wrapping works based on the position of white space between words. To enable auto wrap, set the AllowTextWrap property to true. You can configure the auto wrap mode by setting the TextWrapSettings.WrapMode property.
There are three types of WrapMode. They are:
- Both: Both value is set by default. Auto wrap will be enabled for both the content and the header.
- Header: Auto wrap will be enabled only for the header.
- Content: Auto wrap will be enabled only for the content.
NOTE
When a column width is not specified, then auto wrap of columns will be adjusted with respect to the DataGrid’s width.
In the following example, the TextWrapSettings.WrapMode is set to Content.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" GridLines="GridLine.Default" AllowTextWrap="true" Height="315">
<GridTextWrapSettings WrapMode="WrapMode.Content"></GridTextWrapSettings>
<GridColumns>
<GridColumn Field=@nameof(Order.RollNo) HeaderText="Roll No" Width="140"></GridColumn>
<GridColumn Field=@nameof(Order.Name) HeaderText="Name of the inventor" Width="70"></GridColumn>
<GridColumn Field=@nameof(Order.PatentFamilies) HeaderText="No of patentfamilies" Width="80"></GridColumn>
<GridColumn Field=@nameof(Order.Country) HeaderText="Country" Width="100"></GridColumn>
<GridColumn Field=@nameof(Order.MainFields) HeaderText="Main fields of Invention" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
RollNo = 1000 + x,
Name = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
PatentFamilies = 1000 + x * 5,
Country = (new string[] { "Australia", "Japan", "Canada", "India", "USA" })[new Random().Next(5)],
MainFields = (new string[] { "Printing, Digital paper, Internet, Electronics,Lab-on-a-chip, MEMS, Mechanical, VLSI", "Various", "Printing, Digital paper, Internet, Electronics, CGI, VLSI", "Automotive, Stainless steel products", "Gaming machines" })[new Random().Next(5)],
}).ToList();
}
public class Order
{
public int? RollNo { get; set; }
public string Name { get; set; }
public int? PatentFamilies { get; set; }
public string Country { get; set; }
public string MainFields { get; set; }
}
}The following screenshot represents a DataGrid with auto wrap.
Custom attributes
You can customize the DataGrid cells by adding a CSS class to the CustomAttributes property of the column.
In the following example, the cells of the OrderID and ShipCity columns are customized.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" Height="315">
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" CustomAttributes="@(new Dictionary<string, object>(){ { "class", "e-attr" }})" TextAlign="TextAlign.Right" Width="140"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer ID" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.ShipCity) HeaderText="Ship City" CustomAttributes="@(new Dictionary<string, object>(){ { "class", "e-attr" }})" Width="100"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText="Order Date" Format="d" Type="ColumnType.Date" Width="100"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCity = (new string[] { "Seattle", "Tacoma", "Redmond", "Kirkland", "London" })[new Random().Next(5)],
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public string ShipCity { get; set; }
}
}
<style>
.e-attr {
background: #d7f0f4;
}
</style>DataGrid lines
The GridLines have option to display cell border and it can be defined by the GridLines property.
The available modes of DataGrid lines are:
| 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. |

{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCity = (new string[] { "Seattle", "Tacoma", "Redmond", "Kirkland", "London" })[new Random().Next(5)],
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public string ShipCity { get; set; }
public DateTime? OrderDate { get; set; }
}
}NOTE
By default, the DataGrid renders with Default mode.
Clip mode
The clip mode provides options to display its overflow cell content and it can be defined by the Columns.ClipMode property.
There are three types of ClipMode. They are:
- 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.
NOTE
By default, Columns.ClipMode value is Ellipsis.
