Does anybody know how to change the foreground color of a WPF-Progressbar. It always seems to be merged with green.
just try with this
<ProgressBar Height="25" IsIndeterminate="True" Width="150" Foreground="Red" ></ProgressBar>
If it is not working as you required you have to modify the Style or ControlTemplate of Progressbar.
To do that you can use Expression Blend from Microsoft or you can get a copy the existing template and modify it.
