We recently upgraded to Q2 2009 SP1 AJAX.Net Controls and after doing so are experiencing an error in IE7/IE8 when refreshing one of our grids. The following is a line of code (generated by the grid control itself) that's causing the problem:

if(j.href.indexOf("&ie7CacheFix")>=0){j.href=j.href.replace("&ie7CacheFix","")

(from line 512 of the Telerik.Web.UI.WebResource auto-generated file -- Telerik.Web.UI.WebResource_#.axd -- where # is a random number).

This does not occur when running in Firefox and did not occur prior to installing Q2 2009 SP1.

Has anyone else come across this error and, if so, what did you do to fix it? Telerik -- do you know whether this is a known issue?

(I searched the web for a solution and think this may be related to IE reloading background images on the page in question. Since this doesn't occur in Firefox, it may be related, but I'm not positive.)

Hmm... its a strange issue. My scenario is slightly different than yours in that I don't have an AjaxPanel. I have a RadGrid, with a RadComboBox nested inside as the Grid EditTemplate. When I try to put the grid into Edit mode, I randomly receive an error from line 512 of the Telerik.Web.UI.WebResource file:
if(j.href.indexOf("&ie7CacheFix")>=0){j.href=j.href.replace("&ie7CacheFix","")

When the error occurs, the RadComboBox does not have a skin and it says "select" where the drop down arrow should be. Sometimes the user could use the application for 10 minutes without error (and the skin displays correctly), and other times the error occurs immediately.

I'm stumped on this one.

It seems to have something to do with the RadAjaxPanel. If EnableAJAX=false on my wrapper panel, the error goes away.

AHA!

I have discovered (and I should have guessed from the start considering the script error displayed) that this error is in relation to Custom Skins within our project.

Once I remove the Theme property from the Page element in the web.config, which removes the theme containing all custom skins, the problem goes away.

The code seems to want to alter the autogenerated LINK elements in the style class Telerik_stylesheet. removing &ie7CacheFix portion and replacing it with string.empty, which is apparently an unwelcome value.

Any insight from Telerik?

answered on 30 Oct 2009, 04:09 PM

Indeed I have eliminated the exception.

We implemented a Theme with a single skin file. Within the skin file was defined (initially) each RadControl we made use of, EmbeddedSkins where set to false and a Skin was assigned from the App_Themes folder.

It appears, unfortunately, that our list of used RadControls in the application grew (specifically causing the problem I think the RadDateTimePicker), but our skin file did not define some of the additional controls we had begun to make use of. I went through and specifically defined each and every Rad Control in the skin file and the problem disappeared.

I believe this is just a minor bug in the Telerik JS. I am having the issue if I disable ajax in the onRequestStart event of the RadAjaxManager.If I then use a tabstrip afterwards, it produces the error in the subject.

But I believe this is the solution

The value of href is

"/WebResource.axd?d=91oH34zN0iY_rhxsy9FTx3hDCktY3-dsyyLE3G_Ogwb6NJkU0PpAbW18Wbds2HZa0&t=633894727840000000&ie7CacheFix"

The original line fails with the error we all know and love, that is the subject of the message

(j.href.indexOf("&ie7CacheFix")>=0){j.href=j.href.replace("&ie7CacheFix","")

The solution would be if the line said (correction in bold)

if(j.href.indexOf("&ie7CacheFix")>=0){j.href.value=j.href.replace("&ie7CacheFix","")

That sets href to equal

"/WebResource.axd?d=91oH34zN0iY_rhxsy9FTx3hDCktY3-dsyyLE3G_Ogwb6NJkU0PpAbW18Wbds2HZa0&t=633894727840000000"

Which is what I believe the intent of the line was in the first place.

Any chance this solution can make it in Q3 (assuming it passes your internal testing)?

Thanks in advance.
