I want to display a error message in a Message box in C#. So i tried the following :
-Sometimes the alert message is popping out and sometimes its not popping.
-Sometimes after it popps out, after i close the browser window, it gives me the following error:
"Microsoft Jscript Runtime Error:
Handler was not added through the SYS.UI.DOMEVENT.ADDHANDLER method."
-can anyone explain what went wrong?
