How do I select row's header in radgridview

Dear All,

I have a problem.

Due to customer requirements, I set the SelectionMode attribute of radgridvbiew to CellSelect.

But I find that I can't select the whole row, because the row's header can't be selected

But I can't change the SelectionMode to FullRowSelect.

What should I do?

Who can help me?

Best wishes
