Question

ASP.NET newbie here. When on a page I’d like to set the corresponding menu item to selected. My approach is this:
On Home.aspx.cs:

Menu menu = (Menu)Master.FindControl("Menu1");

if (menu.Items.Count > 0)
{
    menu.FindItem("Home").Selected = true;
}

Trouble is, menu.item.count == 0 .
My menu is bound to a sitemap, if that matters.

I think you must set the selected item on MenuItemDataBound event (adapt your code):

protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
{
    if (SiteMap.CurrentNode != null)
    {
        if (e.Item.Text == SiteMap.CurrentNode.Title)
        {
            e.Item.Selected = true;
        }
    }
}

To have a menu link built from web.sitemap open in new window…

In asp.net page add OnMenuItemDataBound event:

<asp:Menu ID="mnuFooter" runat="server"
DataSourceID="SiteMapDataSource1"
OnMenuItemDataBound="mnuFooter_MenuItemDataBound">
</asp:Menu>

In web.sitemap, add a ? character to the url:

In code behind, capture the MenuItemDataBound event:

protected void mnuFooter_MenuItemDataBound(Object sender, MenuEventArgs e)
{
    if (e.Item.NavigateUrl.Contains("?"))
    {
        e.Item.Target = "_blank";
    }
}

Any url in the web.sitemap that contains a ? will open in a new window. Note, use any other valid url character in place of the ? if necessary.
