I have a page that has a Grid on it. It also has a UserControl that contains a button. How do I add an AjaxSetting to the AjaxManager so that when the Button is clicked, the grid will be updated?
In case of WebUserControls or Master/ContentPages, one should place RadAjaxManager instance on the main/master page and add a proxy control to the user control/content page. Check the following help documentation for more. RadAjaxManagerProxy
