RadAjaxManager: Javascript problem (c.startsWith is not a function)

[Ferdinand]

Hi,
I got a really weird problem. I implemented a RadTabStrip, a RadToolBar and a RadAjaxManager (and some standard ASP.NET controls) on some page. With the TabStrip I navigate between the pages.
On some (NOT all) of them I get a Javascript error with this Firebug message:
c.startsWith is not a function
Type.registerNamespace("Sys.WebForms");S...s.UI._UpdateProgress",Sys.UI.Control);\r\n                      Telerik....:58366029 (Zeile 15)

Following the link of this error leads me to the following code: if(c.startsWith(b[a]+"_")) in an enless line of Javascript code. Here is the line:

I tried to reproduce the error to attach a little project but that is somehow impossible. I only get it in my project.
If I remove the RadAjaxManager from my pages the error does not occur any more. But this is impossible because I need it to reload data on AjaxRequests.

Did anyone have this problem before? If you need any further information let me know.
I would be really glad for any help on this issue.

Best regards
Ferdinand

Hi Ferdinand,

I suggest that you send us the simple project you prepared as well as the problematic page code. Thus we could get better idea of your scenario and what you are trying to achieve and try finding what could be the reason for the real project page not to work as expected.

Looking forward your reply,

Hi Iana and thanks for the answer.
I will try to prepare something and send it over to you but I am afraid I will not make it before Monday.

Best regards
Ferdinand

Did you ever resolve this issue?  I am getting the same error on my RadTabStrip.

Hi,
sorry I never resolved it. I wasn't even able to prepare a (not) running test project. I removed the RadAjaxManger from the pages where the error appeared, but never found a solution for the problem itself. If you are lucky to get a test project to telerik perhaps you could post the answer here.

[Blop]

I get the exact same problem....

Any idea to solve it?

[Maria Ilieva]

Hello Blop,

We were not able to replicate the described error locally and no runnable projects which show the issue
have been submitted to us.
In case you can prepare runnable version of your project which demonstrates the error, please open a regular support ticket and send it to us. Thus we will be able to debug it locally and do our best to provide proper solution.

All the best,
Maria Ilieva
