TabControl Background dosen't change with theme

[Ivan]

Hello, i have a problem with background color of RadTabControl.
My project is using WPF. I have used RadTabControl and have some Tabs. For example i have a tab with a Grid. In the Grid i have some RadTextBox, RadComboBox  and RadExpander. When i change the theme to Expression_Black in runtime, the themes of RadTextBox and RadComboBox will be changed automatically. But the Background colors of RadExpander and TabItems will not be changed.
Do i need to do something special for TabItems and RadExpander?
Thanks!

I have located the problem. It is because Grid. Which not changed is Grid's Background. I bind the Background on one of Telerik Control, then Grid will use the same color. But i am not sure, whether it is the best solution.

Hi Ivan,

Unfortunately I wasn't able to reproduce the issue you described. Also I am not sure which control you mean when you say RadTextBox, that's why I used RadMaskedTextInput in my test project.

I attached the project I used when trying to reproduce the issue. Please examine it and let me know if I have missed something.

Regards,

i have resolved the problem. Because i have defined a style for telerik control in MergedDictionary. That makes the control unchanged with themes.
btw. i cannot open ur attach in VS.

but thanks anyway
