hi,
If you are using vb.net then its very simple, declare a column with its id or name and then do the following. You can put this code in the body tag of your page where you define your datagrid and i have implemented checkboxes in every row by this code, different people may use different other techniques. However this works!!
If you have any problems let me know. I hope this helps,
Vikram
