Question

After applying background color to columnheaders, the sort arrow is missing. How to add it back?

Answer 1

I think you're gonna have to re-template the DataGridColumnHeader and add it from there. Here's an example. You're gonna have to add a reference to PresentationFramework.Aero

xmlns:Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"
