        {

            SemisterUpgradeMaster r = new SemisterUpgradeMaster();

            DataGridViewRow row = new DataGridViewRow();

            row = DataGridView3.Rows[e.RowIndex];

            // Will put the value of the first column of the selected row into the textbox

            r.label2.Text = row.Cells[0].Value.ToString();

            r.txtsn.Text = row.Cells[1].Value.ToString();
