JavaScript IntelliSense issue with Q1 2010 release

[Telerik Admin]

We discovered a few issues with the JavaScript IntelliSense of RadControls for ASP.NET AJAX in the Q1 2010 release.

1. The JavaScript IntelliSense breaks when you include script references to the embedded jQuery:

<asp:ScriptManager ID="ScriptManager1" runat="server">
   <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
    </Scripts>
</asp:ScriptManager>

One solution would be to reference the jQuery scripts from an external location, for example placing them in the root of your web site/web application:

        <asp:ScriptManager runat="server" ID="ScriptManager1">
            <Scripts>
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
                <asp:ScriptReference Path="~/jquery-1.4.2.js" />
            </Scripts>
        </asp:ScriptManager>

2. The to<ControlName> JavaScript IntelliSense helper method causes run time error for the following controls: AsyncUpload, TabStrip, ToolBar, Upload, Scheduler, TreeView, ListBox, ComboBox, PanelBar.
As a workaround you can use the find<ControlName> method instead:

function itemClicked(sender, args) {
   //the normal approach which is broken in Q1 2010 official release
   //var listBox = $telerik.toListBox(sender);

   var listBox = $telerik.findListBox(sender.get_id());
}

The problems have been addressed in the latest internal build of RadControls (upgrade instructions are available here). The issues will be fixed officially in the Q1 2010 SP1 release of the suite, expected in mid April.
