hi tony,

i have tried the fix that you provided but i didnt make any change in my problem.Please help me with another solution. or else pls let me know if i can delete the rows using my custom checkbox column ‘closed’.

and please note even i cant select each row of the grid.every time i click any row in the grid only the same row will remain selected.it will not change the selection.

please remind me if i am missing reference to something.
