Hello,

I have created a DNN module that has a Radgrid inside the dotnetnuke module. When accessing the module I am noticing that I am getting JavaScript errors on the page. The error is:

_2e2 is null

? in ScriptResource.axd?d=0wQxqRcJ1CXPf2LGdlit_6M6aNYNbDGF6evk1hpRXbSo9OUUX0qqpy8D9ziLGtzeZSRxUNZNyuw1&t=633537003434687500@4343()ScriptRe...434687500 (line 4367)

The grid looks like:

                                              </ClientSettings> 
        
                    </telerik:RadGrid>

I am not sure why this is hapening as this is a pretty basic RadGrid. Any help or suggestions would be greatly apperciated.

I debugged the Javascript code and isolated the exact lines where the error is occuring:

var _2a8=Sys.WebForms.PageRequestManager.getInstance();

this._initializeRequestHandler=Function.createDelegate(this,this._initializeRequest);

_2a8.add_initializeRequest(this._initializeRequestHandler);

}

With the error message:

_2a8 is null

_2a8.add_initializeRequest(this._initializeRequestHandler);

Does the RadAjaxManger needed to be added to the page? Is Ajax not turned on? Does the Rad grid need to be placed in a RadAjaxPanel?

Please help
