Hi Sharma,
Thank you for the question.
You can find the answer to your question in your support ticket. I would like to post the answer here as well. Your scenario is possible with RadGridView and I am attaching a sample project to demonstrate this. In order to have a RadGridView with a complex editor (RadComboBoxEditor and RadButton), I am creating a custom cell where I am arranging the RadComboBoxEditor and the RadButton (RadHostItem). Then, on BeginCellEdit I am adding the RadButton with the help of a RadHostItem. When the editor is closed, the RadHostItem is removed.
I hope this helps. If you need additional questions, feel free to contact me.
Sincerely yours,
Nikolay
