Hello Ashley Roach,
Thank you for the question.
Visual Style Builder saves its layout in a file named docklayout.cfg. If you start the VSB from Start >> Programs >> Telerik >> RadControls for WinForms [version] >> Tools >> Visual Style Builder,
the docklayout.cfg will be saved in a directory similar to this:
C:\Documents and Settings\All Users\Application Data\TelerikCorporation\Telerik.VisualStyleBuilder\2009.3.9.1103
The above directory depends on your Operating System version and RadControls for WinForms version, so in your case it could be slightly different.
If you open Visual Style Builder from Visual Studio and change its layout, the docklayout.cfg file will be saved in a directory similar to this:
C:\Documents and Settings\All Users\Application Data\Microsoft Corporation\Microsoft® Visual Studio® 2005\8.0.50727.762
This path depends on your Operating System and Visual Studio version.
In your case you need to delete the docklayout.cfg file from the Visual Studio application data directory. This will reset the layout of RadDock.
I hope this helps. If you have additional questions, feel free to contact me.
