Hello CPs,

I have created tabs dynamically inside a TabControl using the following code.

C#

string title = "TabPage " + (tabControl1.TabCount + 1).ToString();
TabPage myTabPage = new TabPage(title);
tabControl1.TabPages.Add(new BrowserTab());

where BrowserTab is a class created using

C#

public class BrowserTab : TabPage
    {
        WebBrowser wb = new WebBrowser();
        public BrowserTab()
        {
            wb.Dock = DockStyle.Fill;
            this.Controls.Add(wb);
        }
    }

How can I access the newly created webbrowser control inside the dynamically created tab?

Solution 1

for the TabControl use this:

C#

TabPage myTabPage = new TabPage(title);
myTabPage.Name = "tab" + tabControl1.TabCount;
tabControl1.TabPages.Add(new BrowserTab());

While inside the BrowserTab class you can use:

C#

public class BrowserTab : TabPage
{
    public WebBrowser Browser { get; private set; }
    public BrowserTab()
    {
        Browser = new WebBrowser();
        Browser.Dock = DockStyle.Fill;
        this.Controls.Add(Browser);
    }
}

So you can just do:

C#

var tab = tabControl1.TabPages.OfType<browsertab>().FirstOrDefault(t => t.Name == "tab5");
if(tab != null)
    tab.Browser.Refresh();

Another sub question: after creating that method how to call Browser.DocumentCompleted for that tab;
Can something like this be done?
tab.Browser.DocumentCompleted() {
MessageBox.Show("Content Loaded");
}

I prefer the solution you have proposed, but you can also expose the event like this:
<pre lang="c#">
public class BrowserTab : TabPage
{
public event WebBrowserDocumentCompletedEventHandler DocumentCompleted;
public WebBrowser Browser { get; private set; }
public BrowserTab()
{
Browser = new WebBrowser();
Browser.DocumentCompleted += (snd, evt) => { if (DocumentCompleted != null) DocumentCompleted(snd, evt); };
Browser.Dock = DockStyle.Fill;
this.Controls.Add(Browser);
}
}
</pre>
