Use of PointToRowCol method

To retrieve the row and column index from the mouse position, the PointToRowCol() method can be used. In the below example, the row, column indices are taken from the mouse down point.

this.gridGroupingControl1.TableControl.MouseDown += TableControl_MouseDown;
 
void TableControl_MouseDown(object sender, MouseEventArgs e)
{
   System.Drawing.Point _Ponto;
   _Ponto = new System.Drawing.Point(e.X, e.Y);
   int row, col;
   gridGroupingControl1.TableControl.PointToRowCol(_Ponto, out row, out col);
   MessageBox.Show("Row :" + row + "\n" + "Col   :" + col);
}

Private Me.gridGroupingControl1.TableControl.MouseDown += AddressOf TableControl_MouseDown
 
Private Sub TableControl_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
   Dim _Ponto As System.Drawing.Point
   _Ponto = New System.Drawing.Point(e.X, e.Y)
   Dim row, col As Integer
   gridGroupingControl1.TableControl.PointToRowCol(_Ponto, row, col)
   MessageBox.Show("Row :" & row + Constants.vbLf & "Col   :" & col)
End Sub
