AjaxManager works only one time

[Stan]

I need to call page method from JavaScript:

protected void OnAjaxRequest(object sender, AjaxRequestEventArgs e)
 {
     //TODO:
 }

I added AjaxManager:

<telerik:RadAjaxManager id="AjaxManager" runat="server" OnAjaxRequest="OnAjaxRequest" />

and JavaScript function which is being called when checkbox is clicked:

function OnRowChecked(id, checkBox){
    var ajaxManager = $find("<%= AjaxManager.ClientID %>");
    if (ajaxManager != null)
        ajaxManager.ajaxRequest(id);
    else
        alert("No ajaxManager");
}

This works great - checkbox is clicked, JavaScript is called, page method is called. The only problem is that it works only one time. When second checkbox is clicked  AjaxManager is not found.  I could not add AjaxManager on Page_Init because of another weird javascript error.  This user control is deployed to SharePoint...

Hi Stan,

Could you please ensure that you are using the latest version of RadControls for ASP .Net Ajax. In the latest version we apply a fix namely for such issue cause by incorrect event creating of the RadAjaxManager. If you are up to date please try using regular asp UpdatePanel or RadAjaxPanel and verify of this makes any difference.

Maria:

No, the version it is not the latest - 2010.2.713.35. Is there a hotfix I can apply?

Hello Stan,

The fix is available in the latest official release Q2 2011 of RadControls. So I would suggest you to upgrade your application and verify of this works for you.
