Migrating From RadPanelBar ASP.NET to ASP.NET AJAX

To migrate a Web application from RadPanelBar "Classic" to RadPanelBar for ASP.NET Ajax you need to follow these steps:

  1. Make sure you have installed ASP.NET AJAX. Info can be found at http://ajax.asp.net/docs/InstallingASPNETAJAX.aspx

  2. If your web application is not using ASP.NET AJAX you need to configure it to do so. Detailed instructions can be found at http://ajax.asp.net/docs/ConfiguringASPNETAJAX.aspx (Look for the topic called "Adding ASP.NET AJAX Configuration Elements to an Existing Web Site".)

  3. Add a ScriptManager control to the page (or user control) in which you want to add any RadControls "for ASP.NET Ajax": <asp:ScriptManager ID="ScriptManager1" runat="server" /> If your page is a content page you can add the ScriptManager control in your master page. For further details about the ScriptManager control, see http://ajax.asp.net/docs/overview/ScriptManagerOverview.aspx.

  4. Drag and drop a control from the RadControls for ASP.NET Ajax package or manually copy the Telerik.Web.UI.dll in the Bin folder.

  5. Replace the classic RadPanelBar directive <%@ Register TagPrefix="rad" Namespace="Telerik.WebControls" Assembly="RadPanelbar.NET2" %> with the new one of RadPanelBar "for ASP.NET Ajax": <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
