How to cancel editing a cell? Missing event property
posted

Hello,
in my WebDataGrid I want to let the user add new records. The first column is the key column and the values entered into this field have to be unique. So I wanted to use the CellEditing_ExitedEditMode event.

Here I want to validate the entered value and if the entered value is already in that grid I tried to use "eventArgs.set_cancel(true)". I know this property is available in eventArgs of the CellEditing_EnteringEditMode event and also the method to set that value.

see screenshot2

Unfortunately a similar property and the method are not available in the CellEditing_ExitedEditMode as you can see in screenshot 2

Why is that property and method not available? Has this a special reason? If I can prohibit editing a cell I think it should also be possible to cancel editing. How can I do that now?
