I have just upgraded my applicaiton to use version 2008.1.415.35 (I was previously using Prometheus) then the column filters stop working anymore if you specify the DataSourceID attribute of the RadGrid to the id of a XmlDataSource. It just always display all items in the datasource.
Also, the selected filter option is not highlighted in the two new skins. (Sunset and Hay)

I tried implementing Filtering with the RadGrid and it is working as expected. Have you set the AllowFilteringByColumn property to true?

The AllowFilteringByColumn property is set to true, (the grid works fine in previous version) I have created a test page to demonstrate this problem, below is the code.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="RadGridTest.aspx.cs" Inherits="AJAXEnabledWebApplication1.RadGridTest" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

Here is the Xml file

<Item name="Item 1" description="some description"/>
<Item name="Item 2" description="testing"/>
<Item name="Item 3" description="testing 2"/>
