Conditionally hide or show Aspx Menu Control Item

Question

如何根据后端条件隐藏或显示菜单项？

Answer 1

Found a few links. Basically it looks like this will do the trick...

MyMenu.Items(1).Visible = False

Any of those should give you what you need to hide menu items.

Answer 2

I think you need to remove it from the Menu:

protected void MyMenu_MenuItemDataBound(object sender, MenuEventArgs e)
    {
        if (e.Item.Text == "Menu Item To Remove")
        {
             MyMenu.Items.Remove(e.Item);
        }
    }

Answer 3

Try this:

Public Boolean Condition
{
   get { ... }
}


<asp:Menu ID="..." runat="server">
  <Items>
    <asp:MenuItem Text="..." Value="..." Visible="<%# this.Condition %>" />

    .....
  </Items>
</asp:Menu>

Answer 4

You can remove that particular menu item as follows:

MenuItem mnuItem = mnu.FindItem(""); // Find particular item
mnu.Items.Remove(mnuItem);
