Disappearing of controls from design view

Question

Hi All,
I'm developing a C# application and i've different controls placed in two tab pages.Once i got an error while running the application. From that time onwards i was unable to view the controls in the 2nd tab page but i can view those controls when application is running. But i'm not getting any error in while compiling.


Please tell me how can restore the controls in my design page/
