Multiple RadGrids Produces Javascript Errors

[KobusVisagie]

I have multiple RadGrids on the same page, they all display different data and they all have different names. When the page loads, I get this error:

Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Parameter name: element

This leads to the filtering on the RadGrids not working properly, or it's very slow. Do you have a solution for this problem?

Any suggestions? Do you need more information from me before you can help me?

Hello Gregory,

I recommend that you try the solutions posted in the following threads:
Js Error Sys.ArgumentException: Value must not be null for Controls and Behaviors.
Radgrid inside radmultipage : Error: Sys.ArgumentException: Value must not be nul...
AJAX + Column Filtering problem

Let me know if the problem still persists.

Hello Daniel,

None of the above examples helped me, perhaps the way I have my website setup incorrectly. I have a Master Page and obviously a bunch of content pages. On my Master Page I have a RadScriptManager (which just replace the normal ScriptManager of ASP.NET), a normal ASP.NET UpdatePanel and a normal ASP.NET ContentPlaceHolder inside the UpdatePanel.

Look at it this way: My website has only had the standard ASP.NET control and wherever I had GridView controls, I replaced them with RadGrids. Maybe I'm doing it wrong? Am I leaving something out? Is something else required?

The content page that contains the various RadGrids are only separated by normal <div> tags, I'm not using anything like RadAjaxManagerProxy, RadTabStrip, RadMultiPage, RadPageView, Ajaxsettings etc as per the above posts.

Thanks
G

Hello Gregory,

This error can occur in various scenarios (not necessarily related to Telerik controls) however it is hard to guess the problem without having more information/code. Can you post (or attach) the contents of the problematic page so that we can examine it?

Kind regards,
