Changing ListView Column Headers color.

Recommended Posts

JAFN

I feel like I am missing the obvious (again - sigh) but I can't find how to change the color of a ListView Column Header.

I'm trying to change the whole header not just one cell, although that would be fine too.

Thanks

Not sure if this is possible but a simple code to play with might be nice.

Not as straightforward as the usual custom drawing.

The ListView must be subclassed to get at the NM_CUSTOMDRAW notification sent to the ListView

from the child SysHeader32 control.

The ListViews header control Theme/Visual Style must be turned off in order to paint the columns.

With all the things you can do to the header you'd think a basic color setting would be a built in feature. Maybe in a future version.

I find I am understanding more and more but this is well beyond me.

I think I'll chock this one up to to convoluted for the non-importance to the project.

Thank you for your time.
