Javascript error on RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("radalert('your text')")

[Ed Staffin]

Hi,
It was suggested to be by Vlad that I should be able to throw an alert from the server side with the following code:
    RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("radalert('your text')")

When I tried it, I got this error message.
      Microsoft JScript runtime error: 'undefined' is null or not an object

It was in the telerik.web.ui javascript on line 11869, basically, GetRadWindowManager returned 'undefined'

window.radalert=

function(_1,_2,_3,_4){

 

var

_5=GetRadWindowManager();

 

var

_6=_5._getStandardPopup("alert",_1);

Any help would be great.
BTW, I have both a window manager and a ajaxmanager on the page.
Thanks ... Ed

Hello Ed Staffin,

The correct syntax should be:

Telerik.Web.UI.RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("Sys.Application.add_load(function(){radalert('Welcome to RadWindow <b>Prometheus</b>!', 330, 210);})")

Please check the following KB article for additional information (note that you are using the ASP.NET AJAX version of the controls)
