public event EditorEventHandler ShownEditor
Public Event ShownEditor As EditorEventHandler
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. |
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:
private void TableView_ShownEditor(object sender, DevExpress.Xpf.Grid.EditorEventArgs e) {
Dispatcher.BeginInvoke(new Action(() => {
e.Editor.SelectAll();
}));
}
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
