I got a radgridView with an autogeneratingColumn to false
This radGidview show some line with some column Checkbox (not fix column count, depend on data), see attached file. My goal is when user double click header row, all row checkbox will be checked, and the best of the best would be I could put a row checkbox in the header row but I don't think it's possible.
I also tried to put some command line like a button column but I can't get the right selected row when button is first clicked.
See below for the autogenerating column event :
So how Can I got a double click on header row or insert a checkbox into header row ?
