I want to draw some marks over UltraProgressBar. I inherited from UltraProgressBar and overrided OnPaint method like this:
protected override void OnPaint(PaintEventArgs pe) { base.OnPaint(pe); using (Graphics gr = this.CreateGraphics()) { gr.FillRectangle(Brushes.Red, new Rectangle(10, 10, 10, 10)); } }
It's Ok when SupportThemes is true, but...! But when i want to switch SupportThemes to false it's broke at one stroke. No one of my marks is drawn.
What you will advise?
I don't think that OnPaint is the right place to do this. Your best bet is likely to use a DrawFilter, examples of which can be found in the KB, as well as shipping with the NetAdvantage SDK. You might also find the UIElementViewer handy.

tnx. I'll try
It's work!
below will be for myself :)
