Here Is A different way to get the source <Long Version>. This method will explain a small amount of what we can do with the .Net language, it will show you a simple way to use an interface. <Please Note: If You are familiar with how to do so please do not downvote the tip/trick as there are people who don't, but I do encourage anyone to build onto or post a better method of doing such> First we have our WebData Class which will return the source of the page, inside this class is where our interface and SourceCode class which implements our Source interface. Here is what the class looks like
 
internal abstract class WebData
        {
            internal static Source HtmlSource { get; set; }
            private static String webSource(String url)
            {
                return Encoding.ASCII.GetString(new WebClient().DownloadData(url));
            }
            internal interface Source
            {
                String Get(String url);
            }
            internal class SourceCode : Source
            {
                public String Get(String url)
                {
                    try
                    {
                        if (HtmlSource == null)
                            return String.Empty;
                        else
                            return webSource(url);
                    }
                    catch { return String.Empty; }
                }
            }
        }
 
Now outside of you code block to call this class just add this line of code.
 
private WebData.Source source = new WebData.SourceCode();
 
I have my WebBrowser which is webBrowser1 set within a tabpage in a tabControl. this TabPage is the only tabPage in the TabControl and I have a a custom TabPage Control. the code for this custom TabPage Looks like this
 
internal class SourcePage : TabPage
        {
            private WebBrowser sourceBrowser = new WebBrowser();
            internal SourcePage(string source)
            {
                this.Controls.Add(sourceBrowser);
                sourceBrowser.Dock = DockStyle.Fill;
                sourceBrowser.DocumentText = source;                
                sourceBrowser.IsWebBrowserContextMenuEnabled = false;
                sourceBrowser.WebBrowserShortcutsEnabled = false;
            }
            //This method is for Demonstration purposes, it will remove the tab page from the TabControl automatically
            // when leaving this tabpage. Ex when you go back to Tapbage holding the default webpage
            protected override void OnLeave(EventArgs e)
            {
                base.OnLeave(e);
                base.Dispose();
            }
        }
 
Now To call this method you can place with a buttonClick event, menuClick and so forth. Here is how to call the new tabpage with the source to display in the the tabcontrol.
 
private void getSourceMenuItem_Click(object sender, EventArgs e)
        {
            WebData.HtmlSource = source;
            string SourceData = WebUtility.HtmlEncode(source.Get(webBrowser1.Url.ToString()));           
            tabControl1.TabPages.Add(new SourcePage(SourceData));
        }
 
Here is a complete copy and paste to check how it works below
