    I upgraded RadControls for WinForms from version Q2 2007 to Q1 2009 following the instructions in the documentation...

    0) Uninstall all old versions of Telerik controls for WinForms including the trial versions of our controls

    1) Remove all Telerik WinForms assemblies from the GAC

    2) Install the latest version of Telerik Controls for WinForms

    3) Remove all Telerik assembly references from the Solution Explorer of Visual Studio.

    4) Add them anew. Please make sure that all references are to the same version of Telerik Controls for WinForms.

    5) Restart Visual Studio. Please note that VS is keeping references in the memory so this step is essential

    6) Clean and Rebuild your project

    After doing this my tabstrips have lost their look they are just gray boxes with a black border and when clicked they are not shown as "highlighted".  Is there an easy way of fixing this or am I going to have to rebuild the screens that are using the tab control.

    Hi nbahl,

    Thank you for the question.

    From what you have described about the appearance of your RadTabStrips, it looks like you are using one of our predefined themes (different from the ControlDefault). If this is the case, please note that we have put our predefined themes into separate theme components. For additional information, please refer to this blog post. Since you do not have such component on your form, but the ThemeName is still set to a specific theme string (for example "Telerik"), the theme cannot be found and you end up with RadTabStrips with no style.

    I hope this helps. If you continue to experience the issue, please open a new support ticket and send me your project. This will allow me to investigate the case further and provide you with accurate assistance.

    Best wishes,

    the Telerik team
