You need to set datagridview's SelectionMode to FullRowMode .

@ma ouml try this make your SelectedRow as FullRowSelected in datagridview Property private void grid_CellMouseClick(object sender DataGridViewCellMouseEventArgs e) { //Select The Row After you click the Link in the Selected Row. if (e.RowIndex != -1 && e.ColumnIndex == 0) { int index = grid.RowIndex ; num_att = grid.Rows[0].Cell[0].Value.ToString(); etat_att_marche etm = new etat_att_marche(textBox1.Text num_att); etm.Show(); //MessageBox.Show(num_att); } }
