DxGrid.DetailRowTemplate Property

Specifies a template used to display a detail row.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v21.2.dll

Declaration

[Parameter]
public RenderFragment<GridDetailRowTemplateContext> DetailRowTemplate { get; set; }

Property Value

Type Description
RenderFragment<GridDetailRowTemplateContext>

The detail row template.

Remarks

The Grid component allows you to create master-detail layouts of any complexity. To implement the layout with a nested grid, do the following:

  1. Add a master grid to your application.
  2. Bind the master grid to data and add columns to its Columns collection.
  3. Add the DetailRowTemplate to the grid’s markup to create a detail view.
  4. Optional. We recommend that you allocate the detail grid to a separate component. Separation improves the application structure and prevents excessive component redraw operations.
  5. Add a second data grid to the template. Bind this grid to a detail data source that uses the template’s context object as a filter criteria.
  6. Optional. To collapse an expanded detail row when a new detail row is displayed, set the AutoCollapseDetailRow property to true.
@inject NwindDataService NwindDataService

<DxGrid @ref="Grid" Data="MasterGridData" AutoCollapseDetailRow="true">
    <Columns>
        <DxGridDataColumn FieldName="ContactName" SortIndex="0" />
        <DxGridDataColumn FieldName="CompanyName" />
        <DxGridDataColumn FieldName="Country" />
        <DxGridDataColumn FieldName="City" />
    </Columns>
    <DetailRowTemplate>
        <Grid_MasterDetail_NestedGrid_DetailContent Customer="(Customer)context.DataItem" />
    </DetailRowTemplate>
</DxGrid>

@code {
    IGrid Grid { get; set; }
    object MasterGridData { get; set; }

    protected override async Task OnInitializedAsync() {
        MasterGridData = await NwindDataService.GetCustomersAsync();
    }
    protected override void OnAfterRender(bool firstRender) {
        if(firstRender) {
            Grid.ExpandDetailRow(0);
        }
    }
}
