Here's a simple example example of using XmlDataSource and GridView:

the xml file:

<?xml version="1.0" encoding="utf-8" ?>

<root>
  <item>
    <id>1</id>
    <content>content 1</content>
    <author>author 1</author>
</item>
  <item>
    <id>2</id>
    <content>content 2</content>
    <author>author 2</author>
</item>
  <item>
    <id>3</id>
    <content>content 3</content>
    <author>author 3</author>
</item>
</root>

in the aspx page:

<asp:GridView ID="_itemsGV" runat="server"
    DataSourceID="_itemsDS"
    DataFile="~/App_Data/your_file.xml"
    GridLines="None"
    AutoGenerateColumns="false">
 <Columns>
   <asp:TemplateField>
     <ItemTemplate>
       <%#XPath("content") %>
     </ItemTemplate>
    </asp:TemplateField>
 </Columns>
</asp:GridView>

<asp:XmlDataSource ID="_itemsDS" runat="server" XPath="root/item"></asp:XmlDataSource>

That's all. I hope it'll be useful for breshing up your asp.net knowledge everytime you need to write XmlDataSource + GridView :)
