How to remove a MenuItem base on condition
There may be an easier solution, which is to use the MenuItemDataBound event. I use this to hide menu nodes from the Menu Controller . Keeping them in the siteMap allows them to appear in the Menu Controller, but I don't want them in the Menu Controller based on the Roles attribute . Here's my code:
The SiteMap File
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="" title="" description="">
<siteMapNode url="#" title="Home" roles="*" description="This is Homepage" />
<siteMapNode url="" title="About" roles="*" description="This About Page" />
<siteMapNode url="_#" title="Product" roles="ADMIN" description="This is Product Page, Only Role Admin Can access" />
</siteMapNode>
</siteMap>
The ASPX Page
<br />
<asp:Menu ID="NavigationMenu" runat="server" BackColor="#F7F6F3" DataSourceID="SiteMapDataSource1"
DynamicHorizontalOffset="2" Font-Names="Verdana" Font-Size="0.8em" ForeColor="#7C6F57"
StaticSubMenuIndent="10px">
<DynamicHoverStyle BackColor="#7C6F57" ForeColor="White" />
<DynamicMenuItemStyle HorizontalPadding="5px" VerticalPadding="2px" />
<DynamicMenuStyle BackColor="#F7F6F3" />
<DynamicSelectedStyle BackColor="#5D7B9D" />
<StaticHoverStyle BackColor="#7C6F57" ForeColor="White" />
<StaticMenuItemStyle HorizontalPadding="5px" VerticalPadding="2px" />
<StaticSelectedStyle BackColor="#5D7B9D" />
</asp:Menu>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" SiteMapProvider="SitemapSys" />
<br />
The Code Behind
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
NavigationMenu.MenuItemDataBound += new MenuEventHandler(NavigationMenu_MenuItemDataBound);
}
}
void NavigationMenu_MenuItemDataBound(object sender, MenuEventArgs e)
{
SiteMapNode node = (SiteMapNode)e.Item.DataItem;
if (node.Roles.Count > 0)
{
string accessLvl = node.Roles[0].ToString();
string userLogInRoles = "ANONYMOUS";
if ((userLogInRoles .Trim().ToUpper() != accessLvl.Trim().ToUpper()) &&
accessLvl != "*" )
{
e.Item.Parent.ChildItems.Remove(e.Item);
}
}
}
Web.Config
<siteMap>
<providers>
<add name="SitemapSys" type="System.Web.XmlSiteMapProvider" siteMapFile="~/Web.sitemap" />
</providers>
</siteMap>
