    We have a grid and before I modified the Item and InstanceItem template, the header font was white when using the Expression_Dark theme. Now it is black. If you look at your example:, the text changes to white to provide contrast with the dark background.

    However, the back text remains present.

    Hi Paul,

     It is hard to say what may cause such unwanted behaviour as what I see on our online Theming demo looks as expected with Expression_Dark theme. Could you please elaborate a bit more on your concrete scenario? It would be best if you can send us a small runnable sample which demonstrates your writings. Contrary, you may provide us with the exact steps that we should follow to reproduce the unwanted behaviour.

    Hi Evgenia,

    I'm actually running into a similar problem.

    Before the problem occurred, I was previously using RadControls for WPF Q2 2012 SP1. I had a radTimeline control that was using the Dark Expression theme. The group header text was white. And the background of the timeline was black. This allowed the group header text to be easily read.

    The problem occurs after I upgraded to Q1 2013. The group header text changes to black. This causes the group header text to be difficult to read because it is a dark color on the dark background.

    Hello Paul,

    Please note that this has been fixed long time ago and the correct Foreground can be observed in our latest official release version from this online demo (make sure you choose Expression_Dark RadioButton).
    We highly recommend our clients to always download and use the latest version of our controls. The reason behind this is they get all latest bug fixes, new features and full support for our controls.

    On a side note - you might still achieve the same look with your current binaries version with the Timeline control if you use our implicit styles mechanism and NoXAML binaries. Then just change the Foreground of the groups like this:

    <Style TargetType="telerik:TimelineGroupPeriodControl" BasedOn="{StaticResource TimelineGroupPeriodControlStyle}">
        <Setter Property="Foreground" Value="White" />

    If you are not familiar with our implicit styles you can get to know them from our documentation (here).

    Check out Telerik Analytics, the service which allows developers to discover app usage patterns, analyze user data, log exceptions, solve problems and profile application performance at run time. Watch the videos and start improving your app based on facts, not hunches.
