Filter error converting from aspnet to ajax aspnet

[Sheepdog]

I have a website that I am in the Process of converting from telerik aspnet controls to telerik ajax aspnet controls. Notice I said IN PROCESS, some of the pages still contain the old telerik controls.
Also the website uses one master page, which I have converted completely over to ajax aspnet control.

Now I have one page with a radtoolbar, and a radgrid with filters on certain columns. The filters were working properly when the old telerik aspnet radgrid and radtoolbar controls were on the page. now that I have switched them to ajax aspnet controls, the filter has stopped working, and now when i click on the filter icon i get the following java error.

Hi Sheepdog,

I already responded in the support thread you opened with regards to this subject. Here is a quote of my reply for further reference:

From the stack trace of the error you receive it seems that the grid client object is not fully initialized due to some unknown reason. Does removing the RadScriptManager instance from your master page and using regular asp ScriptManager eliminates the exception? Do you get any javascript errors on initial load which might conflict with the proper client grid object initialization?

Additionally, consider moving the RadAjaxManager to your master page and use RadAjaxManagerProxy inside the content page as illustrated on this example:

http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/usercontrol/defaultvb.aspx

Let me know how it goes.

Kind regards,
Sebastian
