Hi, first off thanks for reading.
I am trying to create my own various controls that will have shape effects etc etc. and have stumbled on the first hurdle.

I can successfully paint the border of the control and fill its inner area with the required background color however, when in design mode, when I resize my control, it leaves the previous border behind and does not update.

The painting itself is orking fine, because when I run it in a test app, it appears exactly as it is supposed to - its only during design time that it wont.

Not sure if any1 will be able to help, but heres my code so far: (The part in red is the main part I am having the issue with!)

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

e.Graphics.Clear(
Me.BackColor)

With e.Graphics

Select Case Me.Shape

Case LabelStyle.Normal

Select Case Me.DrawStyle

Case PaintStyle.Solid

Dim GP As New GraphicsPath(FillMode.Alternate)

GP.StartFigure()

GP.AddRectangle(
New Rectangle(BorderSize, BorderSize, Me.Width - BorderSize, Me.Height - BorderSize))

GP.CloseFigure()

Me.Region = New Region(GP)

.DrawRectangle(
New Pen(BorderColor, BorderSize), e.ClipRectangle)

GP.Dispose()

e.Dispose()

Case PaintStyle.Gradient

Case PaintStyle.Texture

End Select

'<<<<<<<<<<<<<<<>>>>>>>>>>>>

Case LabelStyle.RoundedSides

Select Case Me.DrawStyle

Case PaintStyle.Solid

Case PaintStyle.Gradient

Case PaintStyle.Texture

End Select

'<<<<<<<<<<<<<<<>>>>>>>>>>>>

Case LabelStyle.SmoothCornerCut

Select Case Me.DrawStyle

Case PaintStyle.Solid

Case PaintStyle.Gradient

Case PaintStyle.Texture

End Select

End Select

End With

End Sub

Thanks in advance for any support - it is much appreciated since I am new to GDI+ and control authoring.
 
Hi you could try this.

Open the collapsed region tha is written by the designer and just after the ' Add any initialization' statement input this code.

setstyle(resize/redraw,true)

That should solve your problem however like you, i'm quite new to all this aswell.
