Question

I want to recreate a simple browser with tab capability. A new tab has to be created every time the user clicks on “button_addTab” or when the selected web site tries to open a new window.

Here is my code:

Add a new tab by pressing the dedicated button:

private void button_addTab_Click(object sender, EventArgs e)
{
    TabPage addedTabPage = new TabPage("tab title"); //create the new tab
    tabControl_webBrowsers.TabPages.Add(addedTabPage); //add the tab to the TabControl

    WebBrowser addedWebBrowser = new WebBrowser()
    {
        Parent = addedTabPage, //add the new webBrowser to the new tab
        Dock = DockStyle.Fill
    }
    addedWebBrowser.Navigate("www.google.com");

Prevent a site from opening new windows (if you know every webBrowsers name) :

private void specificWebBrowser_NewWindow(object sender, CancelEventArgs e)
{
    WebBrowser thisWebBrowser = (WebBrowser)sender;
    e.Cancel = true;    
    TabPage addedTabPage = new TabPage("tab title");
    tabControl_webBrowsers.TabPages.Add(addedTabPage);
    WebBrowser addedWebBrowser = new WebBrowser()
    {
         Parent = addedTabPage,
         Dock = DockStyle.Fill
    } 
    addedWebBrowser.Navigate(thisWebBrowser.StatusText.ToString());
 }

Now my question is:
How can I modify the second branch of code in order to match all the web browsers created with no names when the first code is called (at one time)?

Answer 1

Try to modify the first function to attach an event handler to newly created browser:

private void button_addTab_Click(object sender, EventArgs e)
        {
            TabPage addedTabPage = new TabPage("tab title"); //create the new tab
            tabControl_webBrowsers.TabPages.Add(addedTabPage); //add the tab to the TabControl

            WebBrowser addedWebBrowser = new WebBrowser()
            {
                Parent = addedTabPage, //add the new webBrowser to the new tab
                Dock = DockStyle.Fill
            };
            addedWebBrowser.NewWindow += specificWebBrowser_NewWindow;
            addedWebBrowser.Navigate("www.google.com");
        }
