There's lots of people here, but you have to actually describe the problem before anyone can help you.

Use the "Improve question" button to update your question. Include a description of what you're trying to do, what you've tried, and what's not working. If you're getting an exception, include the full exception details and the code that throws the exception. Remember to indicate which line in your code the exception is thrown from.

Is it okay now.

So you're getting an unhandled exception? You need to post the full details of the exception, and include the code that throws the exception.

If you can't get the details from the YSOD, then they'll be logged in the Application event log on the server.

getting exception for username already exists at catch. but not able to display that on view.. Exception is "Value cannot be null parameter source"

Then you need to show us the code that's throwing that exception. Include the full exception details, and don't forget to indicate which line of code the exception is thrown from.
