    Hello!

    I´m trying to upgrade my code to the RadControls for ASP.NET AJAX. but get the error Unable to create type 'rad:RadSplitter'. Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

    The error fires at the row declaring radsplitter.

    I´m working in a web solution and the only extern dll I´ve included into reference is Telerik.Web.UI.

    I´ve installed net3.5, but the code worked before with the old radcontrols.

    <%

    @ Register TagPrefix="rad" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
    <rad:RadSplitter id="rs_Content" runat="server" width="100%" Height="1000px" Orientation="Vertical" Skin="Default">

    Hello Per Russberg,

    You said you are using .NET 3.5 and the error message says that the AJAX extensions for .NET 2.0 could not be find - this makes me assume that you have included the Telerik.Web.UI.dll for .NET 2.0 instead of the one for .NET 3.5. Please, note that in order to use the RadControls for .NET 3.5 you should copy the dll from the Bin35 instead of the Bin folder of the controls package.

    I recommend to examine the following online help articles which explains this in details:
    http://www.telerik.com/help/aspnet-ajax/installaddingtovs2008.html
    http://www.telerik.com/help/aspnet-ajax/using-radcontrols-net20-30-35-projects-vs2008.html

    Hi Hagai,

    The above mentioned assembly is a part of the ASP.NET AJAX framework which is available for download in the Microsoft's Download Center.

    Kind regards,
