In the constructor of a form, after the InitializeComponent, I add a ToolStripButton to a ToolStrip. When the form opens the new buttons isn't shown, until I manually move it. I've tried .Update, .Refresh, .Invalidate + .Refresh. I've tried these in the constructor, in form load, in form activate. Nada. How do you get a ToolStrip to repaint after changing the Items collection?

You know... I'm not sure.  Calling Invalidate() will always cause the control to redraw itself.  However, in my test, it worked fine... the button was visible as soon as the form displayed.

Public Sub New()

' This call is required by the Windows Form Designer.

InitializeComponent()

' Add any initialization after the InitializeComponent() call.

Me.ThemedToolStrip1.Items.Add(New ToolStripMenuItem("Howdy"))

End Sub

huh. Well, what I finally got to work was to move it slightly, the call refresh...



' Move it bit to left, then back to original place, then it redraws

me.myToolStrip.Location = New System.Drawing.Point(me.myToolStrip.Location.X +1,me.myToolStrip.Location.Y)

me.myToolStrip.Location = New System.Drawing.Point(me.myToolStrip.Location.X -1,me.myToolStrip.Location.Y)

me.myToolStrip.Refresh()

Good to hear
