Using Custom CSS Classes

Start the Project Designer. In the Project Explorer, double-click on the Employees page node. Assign the following value:

Property Value
Custom Style Tall Wide HomePage

On the toolbar, press Browse. Class Tall hides the menu bar at the top of the page, class Wide hides the side bar and class HomePage replaces the yellow background with the standard home page background. These classes can be used in any combination.

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Maximizer.ascx.cs" Inherits="Controls_Maximizer" %>
<script type="text/C#" runat="server">
    protected void Page_Init(object sender, EventArgs e)
        Page.Header.Controls.Add(new LiteralControl(
            "<style type=\"text/css\">" +
            "body {padding:0px!important;}" +
            // hide the membership bar
            "div.MembershipBar, div.MembershipBarPlaceholder {display:none!important;}" +
            // hide the page header and logo
            "div#PageHeader{display:none!important;}" +
            // hide the page title
            "#PageHeaderLeftSide,#PageHeaderContent," +
            "#PageHeaderRightSide{background-image:none!important}" +
            "#PageHeaderContent div.Title {display:none!important;}" +
            // hide the page path
           "#PageHeaderContent .SiteMapPath {display:none!important;}" +

Visual Basic:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="Maximizer.ascx.vb" Inherits="Controls_Maximizer" %>
<script type="text/VB" runat="server">
    Protected Shadows Sub OnInit(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
        Page.Header.Controls.Add(New LiteralControl(
            "<style type=""text/css"">" +
            "body {padding:0px!important;}" +
            "div.MembershipBar, div.MembershipBarPlaceholder {display:none!important;}" +
            "div#PageHeader{display:none!important;}" +
            "#PageHeaderLeftSide,#PageHeaderContent," +
            "#PageHeaderRightSide{background-image:none!important}" +
            "#PageHeaderContent div.Title {display:none!important;}" +
           "#PageHeaderContent .SiteMapPath {display:none!important;}" +
    End Sub

The ideal method of understanding the stylesheets is through tools such as IE 8 Developer Toolbar or debugging tools in Chrome.
