RadAjaxManager & MultiPageView not working

[Prashanthi]

I get the following Javascript error:
Error: Unable to set value of the property 'control': object is null or undefined
When I add a MultiPageView control to the <UpdatedControls> list in RadAjaxManager.

<telerik:AjaxSetting AjaxControlID="RadGridUser" >
<UpdatedControls>  

<telerik:AjaxUpdatedControl ControlID="RadMultiPage1"/>

</UpdatedControls>

</telerik:AjaxSetting>

On ItemSelected event of RadGridUser, I want to be able to refresh (content and selected page index) of the RadMultiPage control.

Prashanthi:

Take a look at the Microsoft JScript runtime error: Unable to set value of the property 'control': object is null or undefined  forum thread for some potential causes of the error (i.e. controls not fully loaded prior to attempting to access them).

Hope this helps!

I could not find a solution to this in the other thread.
How can I delay the javascript execution so that it executed after all the controls are loaded?

Thanks.

I have not been able to find a solution to this yet.
Getting an error when I add RadMultiPage1 to the <UpdatedControls> collection here:

                   <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                   <telerik:AjaxUpdatedControl ControlID="RadMenu1" />
                   <telerik:AjaxUpdatedControl ControlID="RadGridPermission" />

Hi,

Please note that there are some specifics in adding the RadMultiPage and RadTabStrip controls into the RadAjaxManager settings. Please follow the approach provided in this help topic and verify if this makes any difference.
