    I have a Repeater to which a sitemap is bound, i want to remove or
    hide any node while form load

    <asp:Repeater runat="server" ID="menu"
    DataSourceID="S iteMapDataSourc e1" EnableViewState ="False">
    <ItemTemplate >
    <li>
    <asp:HyperLin k ID="HyperLink1 "
    runat="server" NavigateUrl='<% # Eval("Url") %>'><%# Eval("Title") %></
    asp:HyperLink>

    <asp:Repeater ID="Repeater1"
    runat="server" DataSource='<%# CType(Container .DataItem,
    SiteMapNode).Ch ildNodes %>'>
    <HeaderTemplate >
    <ul>
    </HeaderTemplate>

    <ItemTemplate >
    <li>
    <asp:HyperLin k
    ID="HyperLink2 " runat="server" NavigateUrl='<% # Eval("Url") %>'><%#
    Eval("Title") %></asp:HyperLink>

      Re: Repeater Problem

      To change the number of shown items, it is usually better to operate on the
      datasource than on the bound control.

      If you insist on doing that on the repeater, handle the ItemDataBound event,
      use FindControl method to locate the hyperlink inside the item and set the
      hyperlink's Visible property to false.

              FindControl finds by id. Use

              Dim flLink1 As HyperLink = e.Item.FindCont rol("HyperLink2 ")
