Hi  Try writing Javascript code which will disselect the other checkbox on selection of one checkbox.. This way user is mandatory to select only one checkbox. Let me know if that helps. Thanks

I think I said in your other thread that you should use radio buttons. If radio buttons won't work either then you need to explain better what you need. Don't blame Amit for misunderstanding what you need; your description of what you need is not clear.

hi friend another way of doing it is you can disable rest of the check boxes on CheckBox selection change event. Here is the sample code: for (int i = 0; i { CheckBox chk = (CheckBox)GridView1.Rows[i].FindControl(cbRows); if (chk.Checked != true) { chk.Enable=false; GridView1.DataBind(); } } Please mark as answer if it helps you.
