Hi I have this grid using custom checkbox, where only thing is that I put the rowselect even inside a cellbeginedit. But now I the checkbox header does not work select all or unselect all.
It is not correct to “rowselect event inside a cellbeginedit” it can cause many errors.
You should use flag or some another approach that recognize if some editing is started or to know exactly which one row is selected and so on.
