[Solved] radgrid with GridAttachment Column throws Script Manager error: c00ce514 when using IE 9; no error in Firefox

[Alan Jackson]

I have a radgrid with the grid tied to one datasource and a grid attachment column tied to another one.  The purpose is to just click on the link for the column and have it open the appropriate web plug-in for that attachment.

When I debug the grid in IE 9, I get an exception thrown out of the RadScript Manager.  Line: 6
Error: Could not complete the operation due to error c00ce514. 

From what I can tell, it doesn't even hit the database for the second datasource to retrieve the image when running in IE.

When I run the same code in Firefox, everything behaves as expected.  When I have googled the error, it talks about temporarily turning off Ajax.  My gut feeling is that the Javascript code I have in place is being ignored in IE.  I have set breakpoints in that Javascript code just to make sure it is getting executed and the objects are not null / nothing. 

Any idea what could be going on?  Here is a snippet of the code...

	}, 20000);
	}
}

Hi Alan,

In order to verify that the issue is only replicates in one browser you need to ensure that the option for script debugging is enabled for all browsers.

Sample scenario with an attachment column is illustrated in this online demo.

If you are using Ajax you could try to disable it with the help of the EnableAjax property of RadAjaxPanel and RadAjaxManager and check whether the issue still replicates.
