How can I modify a control in the selected tab - C#

Question

I have a tabcontrol named tabControl1, which includes tabs. Button1 adds a tab to it when clicked and adds a browser and then navigate it to google.com. Button2 should be able to navigate the browser in the selected tab to the text inside Text1.

I could do this easily if C# had pointers like this:

WebBrowser* thebrowser;

Button1_Click(object sender, EventArgs e){
  TabPage newtab = new TabPage();
  WebBrowser newbrowser = new WebBrowser();
  newtab.Controls.Add(newbrowser);
  newbrowser.Navigate("google.com");
  newtab.Click+=delegate {thebrowser = &newbrowser;};
  tabControl1.TabPages.Add(newtab);
}

Button2_Click(object sender, EventArgs e){
  thebrowser->Navigate(Text1.Text);
}

That if C# had pointers. Now how can I achieve this with proper C# code? I hope you understood my question and sorry for any errors.

Thanks in advance :)

Answer 1

For what I understand you need to have more than one tab, so more than one browser open at the same time, so a lobal variable will not work.

One way of doing it would be to search the browser on the selected tab.

Button2_Click(object sender, EventArgs e)
{
    foreach (Control item in page.Controls)
    {
        if (item is WebBrowser)
        {
            ((WebBrowser)item).Navigate(Text1.Text);
            break;
        }
    }
}

Well, i'd probably go the Dictionary<int,Webbrowser> way. Something like:

Dictionary<int, WebBrowser> browsers = new Dictionary<int, WebBrowser>();

Button1_Click(object sender, EventArgs e){
     TabPage newtab = new TabPage();
     WebBrowser newbrowser = new WebBrowser();
     newtab.Controls.Add(newbrowser);
     newbrowser.Navigate("google.com");
     tabControl1.TabPages.Add(newtab);
     browsers.Add(tabControl1.TabCount-1, newbrowser);
}

Button2_Click(object sender, EventArgs e){
     browsers[tabControl1.SelectedIndex].Navigate(Text1.Text);
}
