Im trying to make a nested repeater with 3 levels. I've successfully created
a nested repeater with 2 levels, but when adding the 3rd level I get an
InvalidCastException. What am I doing wrong?

Here is my code:

<asp:Repeater id="level1Repeater" runat="server">
     <itemtemplate>
        <a href="#"><%# DataBinder.Eval(Container.DataItem, "Title") %></a>
        <br>
        <asp:repeater id="level2Repeater" runat="server" datasource='<%#
((DataRowView)Container.DataItem).Row.GetChildRows("L1L2") %>' >
            <itemtemplate>
                &nbsp;<a href="#"><%# DataBinder.Eval(Container.DataItem,
"[\"Title\"]")%></a>
                <br>
                <asp:repeater id="level3Repeater" runat="server"
datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("L2L3")
%>' >
                    <itemtemplate>
                        &nbsp;&nbsp;<a href="#"><%#
DataBinder.Eval(Container.DataItem, "[\"Title\"]")%><br></a>
                    </itemtemplate>
                </asp:Repeater>
            </itemtemplate>
        </asp:Repeater>
    </itemtemplate>
</asp:Repeater>

Code Behind:

private void BindWebsites()
{
     level1Repeater.DataSource = Websites.GetAll();
     Page.DataBind();
}

public static DataTable GetAll()
{
    .......
    ds.Relations.Add("L1L2", ds.Tables["WebsitesL1"].Columns["ID"],
ds.Tables["WebsitesL2"].Columns["ParentID"]);
    ds.Relations.Add("L2L3", ds.Tables["WebsitesL2"].Columns["ID"],
ds.Tables["WebsitesL3"].Columns["ParentID"]);

    return ds.Tables["WebsitesL1"];
}
