Use of PointToRowCol method

To retrieve the row and column index from the mouse position, the PointToRowCol method can be used. In the example below, the row and 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);
}

AddHandler 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 = New System.Drawing.Point(e.X, e.Y)
    Dim row As Integer, col As Integer
    Me.gridGroupingControl1.TableControl.PointToRowCol(_Ponto, row, col)
    MessageBox.Show("Row :" & row & vbCrLf & "Col   :" & col)
End Sub
