Treading and Paint

[Jim Lewis]

I have a simple worker thread that does "BeginInvoke(UpdateUI)". In
UpdateUI I have "panel.Refresh ()" which the debugger shows is
executed. Yet a breakpoint in the panel's Paint handler never gets
called. And the panel is never painted. Can someone clue me in why
Refresh does not cause a Paint?

Jim,

You say "paint handler". Are you overriding the OnPaint method, or
attaching to the Paint event?

Perhaps you could try InvokePaint from your worker thread too.
