The XmlDataSource control is a data source control that represents XML data to data-bound controls.

Because the XmlDataSource control extends the HierarchicalDataSourceControl class, and implements the IDataSource interface as well, the control can be used by data-bound controls to display both hierarchical and tabular, or list-style, data.

The XmlDataSource control is typically used to display data in read-only scenarios.

The following example demonstrates how to bind a TreeView control to an XmlDataSource control with XML data that is defined using the Data property.

<asp:treeview id="booktreeview" datasourceid="books" runat="server">
   <databindings>
      <asp:treenodebinding datamember = "book" textfield = "title" />
      <asp:treenodebinding datamember = "chapter" textfield = "heading" />
      <asp:treenodebinding datamember = "section" textfield = "heading" />
   </databindings>
</asp:treeview>

<asp:xmldatasource id="books" runat="server">
   <data>
      <book title = "book title">
         <chapter heading = "Chapter 1">
            <section heading = "Section 1" />
            <section heading = "Section 2" />
         </chapter>
         <chapter heading = "Chapter 2">
            <section heading = "Section 1" />
         </chapter>
      </book>
   </data>
</asp:xmldatasource>
