DxTagBox<TData, TValue>.ColumnCellDisplayTemplate Property

Specifies a template used to display column cells in the TagBox.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public RenderFragment<TagBoxColumnCellDisplayTemplateContext<TData>> ColumnCellDisplayTemplate { get; set; }

Property Value

Type	Description
RenderFragment<TagBoxColumnCellDisplayTemplateContext<TData>>	The template for column cells.

Remarks

The ColumnCellDisplayTemplate property allows you to customize the appearance of every cell in the TagBox control. The template accepts a TagBoxColumnCellDisplayTemplateContext<TData> object as the context parameter. You can use the parameter’s members to:

• Fetch the associated data item.
• Get information about a cell.
• Access the current column object.

Note

The ColumnCellDisplayTemplate property can be used alongside the CellDisplayTemplate property. If both templates are defined, the column-specific CellDisplayTemplate overrides the global ColumnCellDisplayTemplate for cells within that particular column.

The following code snippet customizes the appearance of all cells in a TagBox control.

Razor

<DxComboBox Data="Accounting.Profits"
            @bind-Value="AnnualProfit"
            EditFormat="{0} ({5:C})">

        <DxListEditorColumn FieldName="Year">
            <CellDisplayTemplate>
                <div style="text-align: left;">
