So just looking at the picture I think I can understand my problem. Using AppStylist UltraButton select by pressing "C"and put the properties UseFlatMode to "True" and UseOSThemes to "False. " Selecting the same UltraButton pressing the "1" I put the UltraButton with the edges of the color I want. THE BIG PROBLEM IS THAT WHEN THE BUTTON BLACK EDGE IS IN FOCUS. ANYONE KNOW WHAT TO DO TO TAKE THIS BLACK EDGE?
I don't see any other way to do this. You should Submit a feature request to Infragistics
If I put the Alpha on the Border to Transparent I lose the whole edge, missing the darker blue border. What I could do and that is not ideal is the image below. Putting ShowFocusRect property to false.
I do not know why it happens only with me because I've seen buttons on other issues without this black border.
Try setting the Alpha on the Border to Transparent.
