Migration from RadWindow for ASP.NET (Classic) to RadWindow for ASP.NET AJAX

You can find below the list of steps to migrate your web applications from the classic RadWindow to RadWindow"Prometheus":

1. To add RadWindow "Prometheus" to an existing ASP.NET web application 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 (check 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 are going to add any controls from the Telerik® UI for ASP.NET AJAX suite. <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 you can check http://ajax.asp.net/docs/overview/ScriptManagerOverview.aspx.

2. Drag and drop a control from the Telerik® UI for ASP.NET AJAX package or manually copy the Telerik.Web.UI.dll in the Bin folder.

3. Replace the classic RadWindow's directive <%@ Register Assembly="RadWindow.NET2" Namespace="Telerik.WebControls" TagPrefix="radW" %> with the new one of RadWindow for ASP.NET AJAX: <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

4. Replace the classic RadWindow's declaration: <radW:RadWindow id="RadWindow1" Runat="server">Sample Content</radW:RadWindow> with the new RadWindow for ASP.NET AJAX one: <telerik:RadWindow RenderMode="Lightweight" ID="RadWindow1" runat="server"></telerik:RadWindow>
