no page design in right, but use this method then error

A page can have only one server-side Form tag.

Then it is working fine. It is wrong with your page design. Your page contains multiple form tags. A page can have only one Form tag.

use this method HttpContext.Current.ApplicationInstance.CompleteRequest()
show this error

Instead of Response.End();

Use HttpContext.Current.Response.End();

or

use HttpContext.Current.ApplicationInstance.CompleteRequest()
