ASP.NET SiteMapPath（Web.sitemap）中的多个根节点

Question

I am implementing a Dashboard kind of web application, where users having different Roles. I have to show Site Map Path at the top pf the page, as user browse the different pages inside the dashboard. I am using asp.net SiteMapPath, how can i use it for Multiple root node. i need to implement multiple root node as per users roles.

Ex:- Admin->Directory1->Directory2->Page1.aspx

Teacher->Directory1->Page2.aspx

Student->Directory2->Page1.aspx and so on.

Where Admin, Teacher, and Student are root node of the path.

It shouldn't be like Admin->Teacher->Directory1->Page2.aspx

Any solution?

Thanks.

Answer 1

您可以使用admin作为根节点，并在asp:Menu定义所有内容，在您的情况下，请使用<asp:Menu ID="mainMenu" DataSourceId="siteMapDataSource" runat="server" StaticDisplayLevels="2" StaticSubMenuIndent="0" /> StaticDisplayLevels="2"将确保始终显示admin，教师和学生，并且缩进将防止其显示为缩进，这是默认情况下定义的。

• three site Map file (For Admin, Teacher, Student) We've placed these sitemap files into the App_Data folder, In the user control, we create a public enum, to represent the different menus available.

   public enum SiteMapMenus 

  { Admin, Teacher, Student , NotSet }

  • Then created a public property to set the menu type at design time.

 SiteMapMenus eMenuToLoad = SiteMapMenus.NotSet; public SiteMapMenus MenuToLoad { get { return eMenuToLoad; } set { eMenuToLoad = value; } } 

• Now, The GetMenuDataSource method reads the required sitemap file as an XML file, then creates and returns a data source that can be bound to the control.

   XmlDataSource GetMenuDataSource(SiteMapMenus menu, string serverMapPath) { XmlDataSource objData = new XmlDataSource(); objData.XPath = "siteMap/siteMapNode"; switch (menu) { case SiteMapMenus.Admin:objData.DataFile=serverMapPath + @"\\App_Data\\Admin.sitemap"; break; case SiteMapMenus.Teacher: objData.DataFile=serverMapPath+@"\\App_Data\\Teacher.sitemap"; break; case SiteMapMenus.Student: objData.DataFile=serverMapPath+@"\\App_Data\\Student.sitemap"; break; default: break; } objData.DataBind(); return objData; } 

• as the data source is now XML, and not in the format returned from the sitemap provider, we need to setup our databindings on the menu control itself.

  <asp:Menu ID="Menu1" runat="server"> <DataBindings> <asp:MenuItemBinding DataMember="siteMapNode" TextField="title" NavigateUrlField="url" /> </DataBindings> </asp:Menu> 

• We can now finally bind the source to the control, and this is all fired off in the Page_Load event handler of the User Control.

   protected void Page_Load(object sender, EventArgs e) { Menu1.DataSource = GetMenuDataSource(eMenuToLoad, Server.MapPath("~")); Menu1.DataBind(); } 

• Using our new menu is now as easy as registering the user control on the page, and specifying which menu to display by setting the MenuToLoad property.

    <DW:MyMenu ID="MyMenu1" runat="server" MenuToLoad="Secure" /> 

Now, You can use different different site map for different different users.....
