How to open a link in webBrowser control in external browser?

Question

I have a textBox and a webBrowser control in my Windows Forms application. Whenever a user enters a HTML code in textBox, the webBrowser control shows its compiled form. The code for this:

private void textBox2_TextChanged(object sender, EventArgs e)
{
    webBrowser1.DocumentText = textBox2.Text;
}

But whenever I click a link in the webBrowser control, it opens it in the same webBrowser control. What I want is that it should open in default web browser of the system. So is there any event for this webBrowser control that handles link clicking?

Answer 1

The easiest way to do this would be to intercept the Navigating event.

public void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    //cancel the current event
    e.Cancel = true;

    //this opens the URL in the user's default browser
    Process.Start(e.Url.ToString());
}

Answer 2

I would like to add something more to this answer,

Coz webBrowser1_Navigating method is executed everytime when the content of the webBrowser is changed.

In your case whenever you set the values to DocumentText this method is called and when there is no url and its default value is about:blank. So we should also check this for otherwise it won't load any content.

    private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
    {
        if (!(e.Url.ToString().Equals("about:blank", StringComparison.InvariantCultureIgnoreCase)))
        {
            System.Diagnostics.Process.Start(e.Url.ToString());
            e.Cancel = true;
        }
    }
