How do I change the appearance of the check box of a particular node.
I have a handle on the UltaTreeNode where can I set the the background color of the check box area only and /or the check mark itself?
For example, it is curently defaulted to green
What version of the controls are you using?
Actually, I don't think the Custom Style UltraCheckEditor will work here because UltraWinTree doesn't use editors for the CheckBoxes you are showing in your screen shot here.
So that leaves either Glyphs or a DrawFilter. If you are using v8.2 or higher, you can use the new GlyphInfo property.
If not, then you will need to use a DrawFilter. If you are not familiar with DrawFilters, search the Infragistics Knowledge Base and you will find lots of articles and samples. Also, get the Infragistics UIElementViewer Utility. It's a huge help when working with UIElements.
