<script runat="server">

  void NavigationMenu_MenuItemDataBound(Object sender, MenuEventArgs e)
  {
    // Get the menu item being bound to data.
    MenuItem item = e.Item;

    // Use the Selected property to select the Home 
    // menu item when the page is first loaded.
    if (item.Text == "Home")
    {
      item.Selected = true;
    }
  }
    
</script>

Remarks

Use the Selected property to specify or determine whether the current menu item is selected.

Note

Although the property can be used to determine whether a menu item is selected, it is more common to use the SelectedItem property.

Only one menu item can be selected at a time in the Menu control.
