I have a very busy data entry form that uses a number of themed controls (e.g. panel, container, toolstrip, etc.) that "paints" very slowly.  When displayed it paints (almost scrolls) from the bottom up. When a childdialog is popped up over this screen and then closed, the underlying portion of the screen that needs to be "repainted" is very slow.  Again, repainting from bottom to top.

Any ideas as to why or how to speed up the screen painting?  All controls that have a ThemeSupport property are set to Full.

I changed my ThemedGroupBoxes and ThemedPanel to render with a solid background but I several ThemedContainer controls which contain ThemedGroupBox controls.  I don't see any properties to render the ThemedContainer with a solid background or turn off gradient rendering.  Right now I have gradient ThemedContainers and a ThemePanel and ThemedGroupBoxex that have a solid background.  Not to attrative. 

How do I make the ThemedContainer have a solid background?

Well, at the moment, you don't.  I will have to add this to my "to-do" list as this control doesn't yet have that functionality.  Sorry. 

Frank,

I was already having to work on that control so I added two properties to it that will be included in the next build: TransparentBackground and RenderBodyAsSolidColor.  This will help improve performance like the other controls.
