DxDataGridColumn.DisplayTemplate Property

Specifies a display template for column cells.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v22.1.dll


public RenderFragment<object> DisplayTemplate { get; set; }

Property Value

Type Description

The template content.



The Data Grid was moved to maintenance support mode. No new features/capabilities will be added to this component. We recommend that you migrate to the Grid component.

The DisplayTemplate property allows you to specify custom content for column cells. Use the template’s context parameter to access a data object and its fields (for instance, you can get a data field value).

Use the EditTemplate property to define a template for a column editor. If you do not specify the edit template, the column uses a standard editor based on the column type.

The code below demonstrates how to use these properties for the Details column. The display template shows the More Info… links. Users can click these links to view details about data rows in a pop-up window. The edit template embeds a Memo into the edit form.
