when I set EnableHeaderContextMenu="true" for radgrd , I use UseStaticHeaders="True" and try to hide some of the column using ContextFilterMenu, I got extra line behind the hiding column -- see attached image, I think this is caused by multiline header how can I get rid of it or make this look better?
how can I make the visible column expand to full grid with instead of leaving empty space for the hidden column?
I tried to remove UseStaticHeaders="True", but still having empty space for hidden column.
Not sure what I missed, I feel I did the same as the demo. But just can not get rid of the ending white space.
