I have a textbox whose text should be of the format "W00000-0000"
i.e if the user enters 123456789 it should automatically show as W12345-6789. How do i achieve this in VB.NET? I tried to use the masked edit control but somehow its not working. Is there any equivalent for validator of ASP.NET? Or can i achieve this using code?

Sorry guys....I got the answer myself....Use a mask edit control and set the "mask" property. Use the "ctltext" property to get the text written in it.
