Error.jpg

AppScreen.jpg

ScriptError.jpg

Hi,

I was developing application using Telerik ASP.Net controls (Version: 2011.1.315.40). My Page have hierarchical grid with export functionality. Export functionality was working properly before. As we added more features it stop working.
Even After going through forums and knowledge base article I am not able to resolve this error. Here I am sending you few pages of application. Please help me to figure out problem why export is not working.

Details of Application:

Application contains master page with RadAjaxManager & ScriptManager. Each control contains RadAjaxManagerProxy to overcome limitation of multiple RadAjaxManager not allowed on same page.

- -MyDashboard Page is container page with various control hosted within page.

- - MyIssueControl hosted within MyDashboard Page. This control contains hierarchical grid. I am just exporting Top Grid (IssueGrid) with default export functionality.

- - MyIssueControl hosts other controls as well.

- -After clicking on default export functionality it doesn’t do anything. It throws scripting error(ScriptError.jpg).

- -After going through forums which advise to register RadAjaxManager events in Control to execute client side code which is not possible using RadAjaxManagerProxy.

- After registering RadAjaxManager event in MyIssueControl to execute function OnRequestStart which will disable Ajax for exporting functionality (as it required for export explain in help documents) its now throwing new error (Error.jpg)

Note: Application will not work as it requires data from db. This application pages are just for reference to figure out issue. Please check attach zip file for error screen shot as well as application pages.

This is very critical project issue. Please help me to resolve ASAP. Thanks for your help.

Thanks,
Atman

Hello Atman,

I replied to your support ticket on the same matter. Please, put your follow up posts in the formal support thread, so that we avoid duplicate ones. Thank you for your understanding.

For others who may see this, here is the reply from the other thread:

I created a small web site containing a RadGrid with a NestedViewTemplate containing a RadTabStrip. In the tabstrip there are two tabs displaying one and the same user control which contains a RadGrid. When I tried to export this to excel, there was no problem and no exception thrown.

Generally, because you have set IgnorePaging to true, the NestedViewTemplate will always be collapsed when exporting, so the problem may be related to some other part of your logic, not exactly the export procedure. Additionally, the Object reference exception is a very general one and without having runnable code to debug, we will not be able to track it down.

All the best,
Tsvetina
