    Hi,

    I am getting below error while trying to xmldatasource with treeview. I gave sample xml and code.

    System.Web.UI.WebControls.XmlHierarchyData does not contain a property with the name 'Text'

    <telerik:RadTreeView ID="RadTreeView2" runat="server" DataSourceID="XmlDataSource1">
        <DataBindings>
            <telerik:RadTreeNodeBinding DataMember="Node" TextField="Text" ImageUrlField="ImageUrl" ExpandedField="Expanded" />
        </DataBindings>
    </telerik:RadTreeView>
    <asp:XmlDataSource runat="server" ID="XmlDataSource1" DataFile="TreeView.xml" XPath="/Tree/Node" />
     
    <?xml version="1.0" encoding="utf-8" ?>
    <Tree>
      <Node>
        <Node Text="Top Admin" Value="Top Admin" ImageUrl="sample.ico" >
        <Node>
         
            <Node Expanded="False"  Text="Second" Value="Second">
              <Node>
                <Node Text="Actual" NavigateUrl="~/Actual.aspx" Expanded="False" ></Node>
              </Node>
            </Node>
         
        </Node>
        </Node>
      </Node>
    </Tree>

    Hi Silver,

    The issue is caused because each node tag in the xml file should have a text property in it and you should not have tag like "<Node>" one with no properties. You can review the TreeView.xml file shown in the Populating from XML on-line demo.

    Hope this will explain the issue.
