When working with an asp:menu control it is nice to have control over what MenuItems get displayed based on user privileges or the state of the application rather than maintaining multiple menu's. ASP.NET makes this very simple by hooking into the MenuItemDataBound event. This event allows you to iterate through all the MenuItems - both parent and child.
Here is a diagram of what I mean by parent child menu items
Hopefully this can save you some head scratching and time when working with your next asp menu.
protected void TitleMenu_MenuItemDataBound(object sender, EventArgs e)
{
MenuEventArgs eventArgs = e as MenuEventArgs;
Menu menu = sender as Menu;
//user not logged in, remove both
if (Membership.GetUser() == null && (eventArgs.Item.Text.Equals("Admin") || eventArgs.Item.Text.Equals("Registered User Pages")))
{
menu.Items.Remove(eventArgs.Item);
}
//user logged in not admin, remove admin
else if (Membership.GetUser() != null && (eventArgs.Item.Text.Equals("Admin") && !Roles.IsUserInRole(Membership.GetUser().UserName, "Admin")))
{
menu.Items.Remove(eventArgs.Item);
}
//user logged in as admin remove user pages
else if (Membership.GetUser() != null && (eventArgs.Item.Text.Equals("Registered User Pages") && Roles.IsUserInRole(Membership.GetUser().UserName, "Admin")))
{
menu.Items.Remove(eventArgs.Item);
}
//user hasn't created a facility remove well link
if (Membership.GetUser() != null && Roles.IsUserInRole(Membership.GetUser().UserName, "User") && eventArgs.Item.Text.Equals("Create New Well"))
{
ProfileCommon p = new ProfileCommon();
p = p.GetProfile(Membership.GetUser().UserName);
Guid guid = new Guid(p.UserId);
UICDataContext db = new UICDataContext();
var facilityQuery = from value in db.UICFACILITYTOCONTACTs
where value.ContactGUID == guid
select value.FacilityGUID;
if (facilityQuery.Count() < 1)
{
eventArgs.Item.Parent.ChildItems.Remove(eventArgs.Item);
}
}
}
