            if ((bool)dataGridView2.Rows[index].Cells[0].Value == true)
            {
                //The data is true
                //Cells[0] is the checkbox control
                //dataGridView2.Rows[index].Cells[0].Value returns an object so you must cast it to a boll using (bool)
            }

in concise way i want to prevent the selection of already existing record .
Before adding first grid selected datarow as one of the rows of datatable to be bind with grid2 (probably it would be check box clicked event), you need to loop through new datatable and see if record already exists - If so, skip adding.

Thus, there would be a foreach loop on second grid datasource table. loop and match the unique rowid that already exists with the rowid of current selected item. If you find a match break the loop and return. If you dont find a match after whole foreach loop comes to an end, add the new record to table. Try!

If you were doing this in ASP.NET, you could have kept a copy of selected record id's on client side and handled the checkbox in Javascript.
