Hello, administrator

    In the past, I used the DataGridView control, but now I use the RadGridView control, but I can't find the EditingControlShowing event, I need this event now,

please tell me what event should I use instead of it

    Please reply me as soon as possible. Thank you

Hello, Ricardo,      

RadGridView provides a very convenient API for editing the cells. The CellBeginEdit is fired when the cell is about to enter edit mode. You can cancel edit mode at this stage by setting the Cancel property to true. In the EditorRequired event you can specify what editor exactly to be shown. You can either leave the default editor or replace it with a custom one. Then, the CellEditorInitialized event is fired when the editor is initialized and visible. This is the appropriate place to introduce final changes to the editor.

I would recommend you to have a look at the following help article demonstrating how handle the editing process in RadGridView:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
