Problem when using radAjaxmanager in Umbraco..

[Kevin]

I have problems using the RadAjaxManager in a CMS called "Umbraco".

when I want to add ajaxsetting in umbraco page dynamically, I got some error .
 
[ArgumentNullException: Value cannot be null. Parameter name: page] Telerik.Web.UI.RadAjaxManager.GetCurrent(Page page) +170 Telerik.Web.UI.AjaxSettingsCollection.AddAjaxSetting(Control ajaxifiedControl, Control updatedControl, RadAjaxLoadingPanel loadingPanel) +294 

here is my simple code

public partial class ProductListSetting :   UmbracoEnsuredPage
    {
    protected void Page_Load(object sender, EventArgs e)
        {

            RadAjaxManager1.AjaxSettings.AddAjaxSetting(save, rgProductList,null);
        }
}

Thanks.

Hello Kevin,

Change your AddAjaxSetting line to this:

RadAjaxManager1.AjaxSettings.AddAjaxSetting(save, rgProductList);

I removed the "null" value that was passed to the LoadinPanel parameter.

I hope that helps.

Hi Kevin,

Please elaborate a bit more on your application. Are you using MasterPages or UserControls in it? If yes, in which page the RadAjaxManager is placed and how you get reference to it? More information on your scenario and the RadAjax settings you have added will help us further research on the issue.

For our situation, the fix was to put the RadAjaxManager.AjaxSettings.AddAjaxSetting after adding the panel to the Controls (Controls.Add(panel)).
