Application_Error Not Invoked From Global.asax

Hi ,

If you have implemented Application_Error event in Global.asax and its not invoked, after all the hard work, You need to make sure to do the following

1. Sometimes in the web.config the CustomError property is set to Off. In this case set it to On.

2. Make sure your Global.asax's bin file (app_global.dll) exists and the modified date is same as your Global.asax file.

3. If you have implemented RadCompression, It will not invoke the Application_Error event until you add the following in your web.config file

<telerik.web.ui>  

    <radCompression>   

        <excludeHandlers>

            <add handlerPath="Global.asax" matchExact="true"/>

        </excludeHandlers>

    </radCompression>

</telerik.web.ui>

4. Still if you are not able to implement it, Use HttpModule to trap an error.

These are some of the common causes of not invoking the error event.

Thanks
