rahulDer 18-Feb-14 2:58am

yes , i got value in role as super admin and so it passes IF condition but inside if condition,that respose.redirect not works and directly go to catch part.

Rahul, please check the error details in exception which you are trapping in catch block. Let us know the error details that you could see in the exception

rahulDer 18-Feb-14 3:05am

EXCEPTION ERROR :Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.

/*it dosnt display any error,directly go to catch part*/
In your question: "it suddenly goes to Catch part and give error message "

:confused: Debug your code to get error details

Response.Redirect Method[^] when called with just one parameter would throw ThreadAbortException. You should pass false as the second parameter and then complete the request. Quoting from the link mentioned above:

MSDN HttpResponse.Redirect Method :
When you use this method in a page handler to terminate a request for one page and start a new request for another page, set endResponse to false and then call the CompleteRequest method. If you specify true for the endResponse parameter, this method calls the End method for the original request, which throws a ThreadAbortException exception when it completes. This exception has a detrimental effect on Web application performance, which is why passing false for the endResponse parameter is recommended

That's the best way to handle it. You may also handle ThreadAbortException specifically in your code.

C#

try
{
    Response.Redirect("AdminDashboard.aspx");
}
catch (ThreadAbortException te)
{
    //do nothing or handle as required
}

Hope that helps!

              }
              else
              {
                  Response.Redirect("ClientDashBoard.aspx",false);
              }
