I have attached a sitemap datasource with treeview to display menu.
how to write code in the treeview .
for example
the menu in treeview is
as follows.
Home
- View books
- login
- Registration.

Who ever wants to view book first need to login first they cannot directly go and click the view books.
so i need to write a code as follows.
if session[user] != null
{
--> then proceed (which means logged in)
}
else
{
go to login page.
}

Create a XML like this and save it in App_Data folder with name BookMenu.xml


<?xml version="1.0" encoding="utf-8" ?>

<BookMenu>

  <Menus>

    <Menu title="Books" NavUrl="Books.aspx" description="Books"/>

    <Menu title="Login" NavUrl="Login.aspx" description="Login"/>

	<Menu title="Registration" NavUrl="Registration.aspx" description="Registration"/>

  </Menus>

</BookMenu>

Then in Page/MasterPage (where Treeview need to be added) add XmlDataSource and a TreeView


<asp:XmlDataSource ID="BookTree" runat="server" XPath="/*/*"></asp:XmlDataSource>

<asp:TreeView ID="TreeView1" runat="server" DataSourceID="BookTree" SelectedNodeStyle-ForeColor="Black"

SelectedNodeStyle-Font-Bold="true" SelectedNodeStyle-Font-Size="13px">

<DataBindings>

    <asp:TreeNodeBinding DataMember="Menu" NavigateUrlField="NavUrl" TextField="title"

    ToolTipField="description" />

    </DataBindings>

</asp:TreeView>

In the Code behind of Page/MasterPage OnLoad just read the xml and assign the datasource


protected override void OnLoad(EventArgs e)

{

	XElement xml = XElement.Load(MapPath("~/App_Data/BookMenu.xml"));

    var _data = from s in xml.Elements("Admin") select s;

	

	BookTree.Data = Convert.ToString(_data.FirstOrDefault());

	TreeView1.DataBind();

}

Thanks,
