Hi

In my VB.net I have a TabControl on a TaskPane as shown in the image.

When I click page three and go back to another page, part of page three still shows

on the right. When I then click the page I have gone to, it dissapears and looks as it should.

What might cause this? Is there a way to simulate the click with code?

Its to do with your custom painting I think.

Hi.

Even if I remove the paint code it still happens. The code on each page looks like the following code. I also use Me.Invalidate behind the click event but it only did once while I was changing the code around. How about if I simulate the Mouse Click event somewhere

   Private Sub TabPage1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles TabPage1.Paint

        Try
            Dim graphics As Graphics = e.Graphics()

            Dim rectBrush As New System.Drawing.Rectangle(0, 0, 450, 600)
            Dim brush As LinearGradientBrush
            brush = New LinearGradientBrush(rectBrush, Color.FromArgb(46, 100, 160), _
                            Color.White, LinearGradientMode.Horizontal)
            graphics.FillRectangle(brush, rectBrush)
        Catch ex As Exception

        End Try
    End Sub
