[quote="NineRays"]Yes, you can create or override from GradientStylist to override filter mark drawing.
Do you have any examples of this? I'd rather not impliment the GradientStyleList as it does a lot of other style items I don't want, I just want to override the FilterMarks for each column type
[quote="NineRays"]Or you can inherit your column class from any of available column classes and override
Column.PaintHeader or
Column.DrawFilterMark to implement your own drawing of header or filter mark.
I did this, but it only overrides columns where I use that custom column type, Consequently I cannot then use any of the standard columns and allow filtering..
