<asp:Login runat="server" BackColor="#DEDEDE" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="10pt"> <TitleTextStyle BackColor="Black" Font-Bold="True" Font-Names="Verdana" Font-Size="10pt" ForeColor="White" /> </asp:Login> Each type of control in Web Forms has different options you can set in a skin file, allowing you to set the appearance of each control in many ways. By making the site theme-enabled, you can easily change the appearance of the site later by creating a new theme directory and similar theme files, and setting the theme property in web.config to use the new theme.

The header region of the page is the title area across the top. It contains a single Label control named PageTitle. This control displays the title of the current content page, based on the Title property set for that page. The following code is included in MasterPage.master to load this value: protected void Page_Load(object sender, EventArgs e) { PageTitle.Text = Page.Title; } As each content page loads, not only does the Load event for the content page run, but so does the Load event for the master page. This means that code can be placed in the master page to run when any content page is loaded in this case, to set the title at the top of the page.

The navigation region displays the navigation links down the left side of each page. To do this, a web.sitemap file and associated SiteMapDataSource control are used to load the overall structure of the site into memory. This data is then data bound to a TreeView control for display to the user. The web.sitemap file is an XML file that contains a node for each page to be displayed in the navigation region: < xml version="1.0" encoding="utf-8" > <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" > <siteMapNode url="" title="" description=""> <siteMapNode url="~/Default.aspx" title="Home" description="Main page" /> <siteMapNode url="~/ProjectList.aspx" title="Project list" description="Project list" /> <siteMapNode url="~/ResourceList.aspx" title="Resource list" description="Resource list" /> <siteMapNode url="~/RolesEdit.aspx" title="Project roles" description="Project roles" /> </siteMapNode> </siteMap> The site map concept can be used to define hierarchical website structures, but in this case, I m using it to define a flat structure. Notice how each <siteMapNode> element defines a page except the first one. That root node is required in the file, but since I m defining a flat structure, it really doesn t represent a page and is just a placeholder. If you were to define a hierarchical page structure, that node would typically point to Default.aspx.

Notice that MasterPage.master includes a SiteMapDataSource control: <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" /> This special data control automatically reads the data from the web.sitemap file and makes it available to controls on the page. The ShowStartingNode property is set to False, indicating that the root node in web.sitemap is to be ignored. That s perfect, because that node is empty and shouldn t be displayed. In this case, a TreeView control in the navigation region is bound to the SiteMapDataSource, so it displays the items listed in web.sitemap to the user.

In the subnavigation region of MasterPage.master, you ll see a LoginStatus control: <asp:LoginStatus ID="LoginStatus1" runat="server" OnLoggingOut="LoginStatus1_LoggingOut" /> This is one of the login controls provided with ASP.NET 2.0, and its purpose is to allow the user to log into and out of the site. The control automatically displays the word Login if the user is logged out, and Logout if the user is logged in. When clicked, it also automatically redirects the user to a login web page defined in web.config. I ll cover the web.config options later. Because the control automatically directs the user to the appropriate login page to be logged in, no code is required for that process. However, code is required to handle the case in which the user clicks the control to be logged out. This code goes in the master page: protected void LoginStatus1_LoggingOut( object sender, LoginCancelEventArgs e) { ProjectTracker.Library.Security.PTPrincipal.Logout(); Session["CslaPrincipal"] = Csla.ApplicationContext.User; System.Web.Security.FormsAuthentication.SignOut(); } This code covers a lot of ground. First, the Logout() method of PTPrincipal is called, which sets the current principal on the current Thread object to an unauthenticated PTPrincipal object. This was discussed in 8 and used in PTWin in 9. However, when the user is logged in, their principal object is stored in a Session field so it can be easily reloaded on every page request. The details on how this works are discussed later in the chapter. When the user logs out, that Session field is updated to reference the new principal object.

s Note If you want to avoid Session, you can choose to reload the user s identity and roles from the security database on every page request. While that avoids the use of Session, it can put a substantial workload on your security database server. In PTWeb, I have opted to use Session to minimize the load on the database.
The final step is to tell ASP .NET itself that the user is no longer authenticated. This is done by calling FormsAuthentication.SignOut(). This method invalidates the security cookie used by ASP .NET to indicate that the user has been authenticated. The result is that ASP .NET sees the user as unauthenticated on all subsequent page requests. This covers the logout process, but the login process requires some more work. While the Login Status control handles the details of directing the user to a login page, that page must be created.
