                Microsoft ASP.NET 3.5 Extensions: Managing Browser History with Client Script</h2>
            <p />
            <div id="Div1" class="new">
                <p>
                    This sample shows:</p>
                <ol>
                    <li>The <code>Sys.Application</code> object and the <code>navigate</code> event and <code>addHistoryPoint</code> method.</li>
                    <li>The <code>addHistoryPoint</code> method demonstrates addition of titles.</li>
                </ol>
            </div>
            <p>
            </p>
            <h2>Example 1: Managing browser history in client script</h2>
            <p>This example includes three buttons. The handler for each button's <code>click</code> event sets
            navigation history points using the <code>Sys.Application</code> object. The script used here, makes use of the 
            <code>Sys.Debug</code> class to dump trace information to the TEXTAREA at the bottom of the page. 
            </p>
            <p>When you click the buttons, and history points are added, you will be able to see the list of history entries and their titles in the 
            "Recent Pages" drop-down in Internet Explorer, for example.
            </P>
            <p>To see history in action, perform the following steps:</p>

            <ol>
                <li>Press <b>1</b>. See the trace output.</li>
                <li>Press <b>3</b>. See the trace output.</li>
                <li>Press <b>2</b>. See the trace output.</li>
                <li>Press the browser's Back button. Notice that the page is refreshed with previous data and 
                that trace information shows this.</li>
            </ol>
            <div id="div2" class="box">0</div><p></p>
                <input type="button" id="clientButton1" value="1" />
                <input type="button" id="clientButton2" value="2" />
                <input type="button" id="clientButton3" value="3" />
            <br /><br />
            <textarea id="TraceConsole" cols="40" rows="5"></textarea>
        </div>
    </form>
