I have a RadColorCombo Picker (Doesnt matter WHAT rad object i use)
and it is updating a RadMenu (also doesnt matter what I update)
I set up ajax manager to update radmenu when colorcombopicker is used.
I get an error as follows:
Microsoft JScript runtime error: Object doesn't support this property or method
Section of code from Telerik.Web.UI.WebResource2_axd is the source  that has the error and the code it highlights is

if

 

 

(f.show(e)){var n={Panel:f,ControlID:e};

 

 

 

if(!Array.contains(this._loadingPanelsToHide,n)){this._loadingPanelsToHide[this._loadingPanelsToHide.length]=n;

 

 

}}}}}}},_initializeRequest:

 

function(e,c){Telerik.Web.UI.RadAjaxManager.callBaseMethod(this,"_initializeRequest",[e,c]);

 

if

 

(!this._isRequestInProgress){return;

}

 

var a=c.get_postBackElement();

if(f.show(e)) is highlighted in the debugger


As an example here is the aspx

 

<telerik:RadColorPicker ID="RadColorPicker1" Runat="server" AutoPostBack="True"

 

 

oncolorchanged="RadColorPicker1_ColorChanged" ShowIcon="True"

 

 

 

SelectedColor="" style="z-index: 4000;" Height="21px">

 

 

 

 

</telerik:RadColorPicker>

 

<

 

 

telerik:RadMenu ID="RadMenu1" Runat="server">

 

 

<Items>

 

 

<telerik:RadMenuItem runat="server" Text="1">

 

</telerik:RadMenuItem>

 

<telerik:RadMenuItem runat="server" Text="2">

 

 

</telerik:RadMenuItem>

 

 

</Items>

 

 

 

 

</telerik:RadMenu>

 

<telerik:RadAjaxManager runat="server"

 

onajaxrequest="RadAjaxManager1_AjaxRequest">

 

 

<AjaxSettings>

 

<telerik:AjaxSetting AjaxControlID="RadColorPicker1">

 

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="RadMenu1" />

 

 

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

</AjaxSettings>

 

 

</telerik:RadAjaxManager>

 

 

Hello Mike ,

Could you please let me know whether the problem persists if the ajax is disabled on the page. Also please let me know what is the result if a regular asp UpdatePanel is used.

Sincerely yours,
