Public Property EditFormTemplate As DataTemplate

Property Value

Type	Description
DataTemplate	The template that defines the appearance of a data editor.

Remarks

The template specified by the EditFormTemplate property is applied to the editor displayed in the edit form.

The EditFormEditor objects defined in the TableView.EditFormTemplate use the EditFormTemplate to display the column’s editor.

Specify Custom Editors

You can use the EditFormTemplate property to specify a custom editor for the column:

• Add a BaseEdit descendant editor.
• Set the editor’s Name property to PART_Editor.

The following example demonstrates a GridControl that displays the inline edit form. The SpinEdit editor is used for the Quantity field.

XAML

<dxg:GridControl ItemsSource="{Binding Source}">
    <dxg:GridControl.View>
        <dxg:TableView EditFormShowMode="Inline"/>
    </dxg:GridControl.View>
    <!-- ... -->
    <dxg:GridColumn FieldName="Quantity">
        <dxg:GridColumn.EditFormTemplate>
            <DataTemplate>
                <dxe:SpinEdit Name="PART_Editor" IsFloatValue="False"/>
            </DataTemplate>
        </dxg:GridColumn.EditFormTemplate>
    </dxg:GridColumn>
</dxg:GridControl>

Data Binding

The template’s data context is a DevExpress.Xpf.Grid.EditForm.EditFormCellData object. Use the following binding paths to access cell values, columns, and ViewModel properties:

• Value - Access the current cell value.
• EditorViewInfo - Access the current column.

• RowData.Source.Row.[YourPropertyName] - Access a property of an object from the ItemsSource collection.

  This property is updated when a user clicks the Edit Form‘s Update button. The following help topic describes how to update the Edit Form‘s editor based on another editor’s value: Process Editor Value Changes.

• RowData.Source.DataContext.[FieldName] - Access unbound column values.
• RowData.Source.View.DataContext.[YourPropertyName] - Access a property in a grid’s ViewModel.
