Blazor Grid - Detail View

Use Blazor Bootstrap grid component to display tabular data from the data source. And it supports client-side and server-side filtering, paging, and sorting.

Example#

To enable detail view, set the AllowDetailView parameter to true. In the following example, existing <GridColumn> tags are nested under <GridColumns> tag to distinguish them from <GridDetailView>.
Razor
<Grid TItem="Product"
      Class="table table-hover border-top"
      Data="products"
      AllowDetailView="true">

    <GridColumns>
        <GridColumn TItem="Product" HeaderText="Id" PropertyName="Id">
            @context.Id
        </GridColumn>
        <GridColumn TItem="Product" HeaderText="Employee Name" PropertyName="Name">
            @context.Name
        </GridColumn>
        <GridColumn TItem="Product" HeaderText="Active" PropertyName="IsActive">
            @context.IsActive
        </GridColumn>
    </GridColumns>

    <GridDetailView TItem="Product">

        <Grid TItem="Ingredient"
              Class="table table-hover border-top"
