<asp:HyperLink ID="HyperLink1"
runat="server" NavigateUrl='<%# Eval("Url") %>'><%# Eval("Title") %></
asp:HyperLink>

<asp:Repeater ID="Repeater1"

SiteMapNode).ChildNodes %>'>
<HeaderTemplate>
<ul>
</HeaderTemplate>

<ItemTemplate>
<li>

</siteMapNode>
</siteMap>

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.

Hi
I tried this code for the above problem

Protected Sub menu_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.RepeaterItemEventArgs) Handles
menu.ItemDataBound
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType =
ListItemType.AlternatingItem Then
Dim flLink1 As HyperLink = e.Item.FindControl("~/
IRF.aspx")
flLink1.Visible = False
End If
End Sub

but giving Error {"Object reference not set to an instance of an
object."}
 
FindControl finds by id. Use

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