VB

I have the following line of codes in the system.

Private Sub DataGridView1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseClick

rcdraw = DataGridView1.GetCellDisplayRectangle(DataGridView1.CurrentCell.ColumnIndex, DataGridView1.CurrentCell.RowIndex, False)
       If DataGridView1.CurrentCell.Selected = True Then
           selection = True
       Else
           selection = False
       End If
   End Sub

Private Sub DataGridView1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles DataGridView1.Paint
     
        If selection = True Then
            DrawEllipseRectangle(e)
        Else
         
        End If
    End Sub

    Private Sub DrawEllipseRectangle(ByVal e As PaintEventArgs)
  
        Dim redPen As New Pen(Color.Red, 3)
        Dim rect As New Rectangle(0, 0, 200, 100)
        e.Graphics.DrawEllipse(redPen, rcdraw)
    End Sub

My intention is to whenever I click on the cell draw an ellipse on the selected cell.

The problem is it draws ellipse only after I click on another cell. It doesn't draw the ellipse whenever I click the cell.

Any ideas please help
