[DXCategory("Editor")] public event EventHandler ShownEditor
<DXCategory("Editor")> Public Event ShownEditor As EventHandler
The ShownEditor event's data class is EventArgs.
Write a ShownEditor event handler to perform specific actions after a cell editor has been invoked. This can be used to set a specific selection within the current editor, for instance. You can access the currently active editor and its value via the TreeList.ActiveEditor and TreeList.EditingValue properties respectively.
Use the TreeList.ShowingEditor event to perform specific actions before an editor is activated.
