I have added 3 columns with checkboxes.
The first is using OnGetCellClass to generate it.
The second is using AddCheckBoxColumn.
The third is using AddDataCheckBoxColumn.
The method I used previously in my project was option 3. Now I can’t select the checkbox and if I click in the whitespace in the cell, I get an exception.
None of these columns allows me to select the checkbox.
Hope this helps!
