There are items in my Web.sitemap that I don't want to see on my Menu control. Is there an attribute I can add to the item in the sitemap to make it invisible or something?

thanks

HI

You can use role management to hide this Items.

HI

Well I don't really want to block the content, the item in question just isnt relevant to that menu and I'm going to have a link to it somewhere else on the site. I just need a few specific items not to show up on the menu. It would be great if I could just add an attribute to the sitemapnodes to hide them.

Hi,

You can use the remove method of the menu to remove the items that you do not want to see from the menu's items. In fact, if you use the remove method, the items just only do not show in the menu control, but the sitemap file will not be changed.

hope it helps.

Amanda is right; this is exactly what I do for pages I don't want on the menu, but that I want to appear in my siteMapPath. I first add a custom attribute to my siteMapnode:

  <siteMapNode title="foo" url="foo.aspx" showInMenu="false" />

You can add any custom attribute you like; in this case I've used 'showInMenu'. Next I handle the MenuItemDataBound event for the menu control, where I check for the attribute and if it is set to false, I remove the node from the menu:

protected void Menu2_MenuItemDataBound(object sender, MenuEventArgs e)
{
    SiteMapNode node = e.Item.DataItem as SiteMapNode;

    // check for the showInMenu attribute and if false
    // remove the node from the parent
    // this allows nodes to appear in the SiteMapPath but not show on the menu
    if (!string.IsNullOrEmpty(node["showInMenu"]))
    {
        bool isVisible;
        if (bool.TryParse(node["showInMenu"], out isVisible))
        {
            if (!isVisible)
            {
                e.Item.Parent.ChildItems.Remove(e.Item);
            }
        }
    }
}

Let me know if you need this in VB.

What language is that in? I need it in VB for asp.net

Hi,

The above code is C# code, you can transfer it to the VB Code by tools:

Protected Sub Menu2_MenuItemDataBound(ByVal sender As Object, ByVal e As MenuEventArgs)
Dim node As SiteMapNode = TryCast(e.Item.DataItem, SiteMapNode)

' check for the showInMenu attribute and if false
' remove the node from the parent
' this allows nodes to appear in the SiteMapPath but not show on the menu
If Not String.IsNullOrEmpty(node("showInMenu")) Then
Dim isVisible As Boolean
If Boolean.TryParse(node("showInMenu"), isVisible) Then
If Not isVisible Then
e.Item.Parent.ChildItems.Remove(e.Item)
End If
End If
End If
End Sub

hope it helps.

thanks,

So i put this code in App_code/hidemenu.vb like this and it doesnt seem to work. am I doing something  wrong?

Imports Microsoft.VisualBasic

Public Class showinmenu
    Protected Sub Menu2_MenuItemDataBound(ByVal sender As Object, ByVal e As MenuEventArgs)
        Dim node As SiteMapNode = TryCast(e.Item.DataItem, SiteMapNode)
        ' check for the showInMenu attribute and if false
        ' remove the node from the parent
        ' this allows nodes to appear in the SiteMapPath but not show on the menu
        If Not String.IsNullOrEmpty(node("showInMenu")) Then
            Dim isVisible As Boolean
            If Boolean.TryParse(node("showInMenu"), isVisible) Then
                If Not isVisible Then
                    e.Item.Parent.ChildItems.Remove(e.Item)
                End If
            End If
        End If
    End Sub
End Class

You need to place the code in the same page as the Menu control (same page if using inline code, or the code-behind page is using code-behind). This is usually the master page, but could be the code file for a user control if that's where your menu is.

HI

You should put it into  Page code behind code where you declare your Menu2. Because this is event handler.

Yeah thats what I did after and it still wont hide the item when I put showInMenu="false" in the sitemap. However, my menu control is not Menu2 its simply Menu so I changed that and still nothing. I know theres nothing wrong with my Master.page.vb because I have other code being executed in it just fine.

thanks

I suspect you need to hook this event into the Menu. Change the event declaration to add the Handles bit, like so:

Protected Sub Menu2_MenuItemDataBound(ByVal sender As Object, ByVal e As MenuEventArgs) Handles Menu.MenuItemDataBound

d

Now I get a NullReferenceException on

 e.Item.Parent.ChildItems.Remove(e.Item)

 HI sebastiencouture

I tried and everything work just fine. I will try to summaries steps:

 
First check your <asp:menu> control for OnMenuItemDataBound:

<asp:Menu ID="Menu1" runat="server" OnMenuItemDataBound="Menu1_MenuItemDataBound" .... />

Second add event handler Menu1_MenuItemDataBound into code behind code.

protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
{

} 

 Third edit your web.sitemap and mark menu items which you don't want to be visible.

<siteMapNode url="~/Test.aspx"      title="Test" showInMenu="false"/> 

I hope this will help you.
