Hi,
I wanted put the code here... but as Network was down.. I couldn't post anything... But after scratching head for 8 hrs , it got resolved.
The resolution was: The DataPropertyName Property of DatagridviewChekbox column was not getting set properly. the actual column to which the checkboxes are going to be bound, was "Column1" and the DataPropertyName was getting set to "Column1 ". (the space was getting added). So just applied trim function and the problem got resolved...
Thanks. :)
