| Type.registerNamespace("Telerik.Web.UI"); |
| Type.registerNamespace("Telerik.Web.UI.WindowManager"); |
| function GetRadWindowManager(){ |
| return Telerik.Web.UI.WindowManager.Manager; |
| } |
| window.radalert=function(_1,_2,_3,_4){ |
| var _5=GetRadWindowManager(); |
| var _6=_5._getStandardPopup("alert",_1); |
| if(typeof (_4)!="undefined"){ |
The error is in the bold line, and the msg is:"Microsoft JScript runtime error: 'undefined' is null or not an object"
It is related to popUpRadMsg. I call it on this way:
| <body onload="msgAlert()"> </html> |
.script goes under the </html>:
.
...
| <script language="javascript" type="text/javascript"> |
| // This code must be in the master and cannot be moved to external js file. |
| // We use String comparsion instead of boolean, to keep the code valid. |
| // if (Convert.ToString(divDisplayMsg.Visible)).ToLower() is accidently empty, no harm is done and the code is still valid. |
| function msgAlert() { |
| var toPopup = "<%=(Convert.ToString(divIsDisplayMsgVisible.Visible)).ToLower() %>"; |
| if (toPopup == "true") { |
| var displayMsgDiv = document.getElementById("<%=divDisplayMsg.ClientID %>"); |
| if (displayMsgDiv) { |
| var msg = displayMsgDiv.innerHTML; |
| //alert(msg); |
| popupRadMsg(msg); |
| } |
| //popupDisplayMsg(); |
| } |
| } |
| </script> |
and on an attached JS file:
| function popupRadMsg(msg){ |
| return radalert(msg, 500, 500); |
| } |
This alert is invoked depending on the visibility of divDisplayMsg. this is set on the server side and allow me to control the popup msg (I can send text and info from server side to it).
Maybe you can tell why is this javascript error occurs?

In ASP.NET AJAX environment, the ASP.NET AJAX controls (including RadControls for ASP.NET AJAX) are created after the page has been loaded. I assume that the problem here is that when you initially try to get a reference to the RadWindowManager, the control is still not fully rendered on the page and that is why getting the error. Try the pageLoad() function to call the msgAlert() function instead of attaching with onload of page body. The function pageLoad() is fired automatically by the MS AJAX client framework when the page is rendered completely. Try the code below and see whether it is working for you.
JavaScript:
| <script language="javascript" type="text/javascript"> |
| function pageLoad() |
| { |
| msgAlert(); |
| } |
| </script> |

I have the same javascript error message. I am tryign to open a new radwindow after postback from server side inside a user control.
protected
void btnAdd_Click(object sender, EventArgs e)
{
if
(!Page.ClientScript.IsStartupScriptRegistered("OpenCheckPopup"))
{
//Some code that needs to be run before calling script.
Page.ClientScript.RegisterStartupScript(Page.GetType(),
"OpenCheckPopup",
"<script type=\"text/javascript\">showcheck(" + ApplicationID + ");</script>");
}
}
In .aspx
function showcheck(applicationId) {
var param = 'addCheck.aspx?ApplicationID=' + applicationId;
showOtherWindow(param, 400, 400);
return false;
}
function showOtherWindow(url, height, width) {
if (window.radopen) {
var oWnd = window.radopen(null, "DialogWindow");
if (oWnd != null && url != null) {
oWnd.set_width(width);
oWnd.set_height(height);
oWnd.setUrl(url);
oWnd.reloadOnShow =
true;
oWnd.center();
oWnd.show();
}
}
}
I have defined the radwindowmanager in .aspx.
I think the page is not fully loaded at this time so it fails to get the reference to radwidnowmanager.
How can I solve this issue?
Thanks,
