Hi Tan,

Thank you for writing.

I guess by "I don't work" you mean that the columns are added but are not always displayed in the correct column. If so, this is caused by the fact that the editors in RadGridView are being reused. For this reason, the CellBeginEdit  event is not convenient for this scenario. You can safely use the CellEditorInitialized to add the desired customization.

I hope this helps. Let us know if we can be of further assistance.
