Remove from SiteMapDataSource ShowStartingNode="false" it throw this exception.

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />

It should work now.

Can you post your definition of <asp:menu> and <asp:SiteMapDataSource> controls and also your web.sitemap file.

Oh I just thought of something..... Could the fact that I'm using the ASP.NET CSS Friendly Control Adapters 1.0 have anything to do with this??

Well thank you for all your help but I'm at my whits end here. I've copied and pasted the code directly and I still get that same error. I'm gonna fiddle with it a bit more though.

HI sebastien

Check your mail.

Re: Omit Items From Menu Using Web.sitemap

sebastiencouture — Thu, 19 Jul 2007 11:48:20 GMT

I've followed the steps exactly and I still get a NullReferenceException on e.Item.Parent.ChildItems.Remove(e.Item).

Could you perhaps email me your pages in VB please at sebastien.couture@gmail.com

Thank you

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.

I hope this will help you.

Regards

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

Dave Sussman — Wed, 18 Jul 2007 14:24:15 GMT

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

Re: Omit Items From Menu Using Web.sitemap

sebastiencouture — Wed, 18 Jul 2007 14:06:20 GMT

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

Re: Omit Items From Menu Using Web.sitemap

Biser — Wed, 18 Jul 2007 12:45:00 GMT

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