error when selecting Cancel on Even_Edit.aspx

May 04, 2008 08:41 PM|rrrodz|LINK

I'm gettign the following error when selecting the cancel button

Server Error in '/ClubWebSite1' Application.

Input string was not in a correct format.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: Input string was not in a correct format.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:



1. Add a "Debug=true" directive at the top of the file that generated the error. Example:



  <%@ Page Language="C#" Debug="true" %>



or:



2) Add the following section to the configuration file of your application:



<configuration>

   <system.web>

       <compilation debug="true"/>

   </system.web>

</configuration>



Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.



Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
