The following code sample shows how to prohibit end users from activating an editor using the mouse:
| Xaml |
<dxg:GridControl AutoGenerateColumns="AddNew" EnableSmartColumnsGeneration="True" ItemsSource="{Binding Items}" SelectionMode="Cell">
<dxg:GridColumn FieldName="Country"/>
<dxg:GridColumn FieldName="City">
<dxg:GridColumn.CellTemplate>
<DataTemplate>
<dxe:ListBoxEdit x:Name="PART_Editor" ItemsSource="{Binding RowData.Row.Cities}" />
</DataTemplate>
</dxg:GridColumn.CellTemplate>
</dxg:GridColumn>
<dxg:GridControl.View>
<dxg:TableView GetIsEditorActivationAction="GetIsEditorActivationAction" />
</dxg:GridControl.View>
</dxg:GridControl>
|
| C# |
private void GetIsEditorActivationAction(object sender, DevExpress.Xpf.Grid.GetIsEditorActivationActionEventArgs e) {
if (e.ActivationAction == ActivationAction.MouseLeftButtonDown)
e.IsActivationAction = false;
}
|
| VB |
Private Sub GetIsEditorActivationAction(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.GetIsEditorActivationActionEventArgs)
If e.ActivationAction = ActivationAction.MouseLeftButton Then e.IsActivationAction = False
End Sub
|
The GridControl provides the following events to process end user actions:
| Event |
