Event Data

The ShownEditor event's data class is EditorEventArgs. The following properties provide information specific to this event:

Property	Description
Column	Gets or sets a grid column, for which an event has been raised. Inherited from EditorEventArgsBase.
Editor	Gets or sets an editor, for which an event has been raised.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Row	Gets the data row for which an event has been raised.
RowHandle	Gets or sets the row handle, for which an event has been raised. Inherited from EditorEventArgsBase.
Source	Gets the View that raised the event. Inherited from EditorEventArgsBase.
Value	Gets the edit value stored in the editor, for which an event has been raised. Inherited from EditorEventArgsBase.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.

Remarks

If you set the EditorShowMode property to MouseUp, the editor’s text is automatically selected when the editor is activated. Otherwise, you can handle the ShownEditor event as follows to automatically select text in the opened editor:

C#

 private void TableView_ShownEditor(object sender, DevExpress.Xpf.Grid.EditorEventArgs e) {
    Dispatcher.BeginInvoke(new Action(() => {
        e.Editor.SelectAll();
    }));            
}

VB.NET

 Private Sub TableView_ShownEditor(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.EditorEventArgs)
    Dispatcher.BeginInvoke(New Action(Sub()
        e.Editor.SelectAll()
    End Sub))
End Sub
