I have RadTabStrip on my page. The problem I try to solve is not allow to pass to other tab if validation is failed.
For that I have next controls:
1. Validation controls connected to the specific control such as:
It is just example. As you see this control validation control is part of the some group
3. Tab Client Event
Once windows is closed in usual situation postback occurs and page is refreshed according to data returned from the windows.
Does anyone know what it might be the reason?
