Examples

The following code example demonstrates how to implement an address bar for use with the WebBrowser control. This example requires that you have a form that contains a WebBrowser control called webBrowser1, a TextBox control called TextBoxAddress, and a Button control called ButtonGo. When you type a URL into the text box and press Enter or click the Go button, the WebBrowser control navigates to the URL specified. When you navigate by clicking a hyperlink, the text box automatically updates to display the current URL.

For the complete code example, see How to: Add Web Browser Capabilities to a Windows Forms Application.

// Navigates to the URL in the address text box when 
// the ENTER key is pressed while the text box has focus.
void TextBoxAddress_KeyDown( Object^ /*sender*/, System::Windows::Forms::KeyEventArgs^ e )
{
   if ( e->KeyCode == System::Windows::Forms::Keys::Enter &&  !this->TextBoxAddress->Text->Equals( "" ) )
   {
      this->WebBrowser1->Navigate( this->TextBoxAddress->Text );
   }
}

// Navigates to the URL in the address text box when 
// the Go button is clicked.
void ButtonGo_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   if (  !this->TextBoxAddress->Text->Equals( "" ) )
   {
      this->WebBrowser1->Navigate( this->TextBoxAddress->Text );
   }
}

// Updates the URL in TextBoxAddress upon navigation.
void WebBrowser1_Navigated( Object^ /*sender*/, System::Windows::Forms::WebBrowserNavigatedEventArgs^ /*e*/ )
{
   this->TextBoxAddress->Text = this->WebBrowser1->Url->ToString();
}

// Navigates to the URL in the address box when 
// the ENTER key is pressed while the ToolStripTextBox has focus.
private void toolStripTextBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        Navigate(toolStripTextBox1.Text);
    }
}

// Navigates to the URL in the address box when 
// the Go button is clicked.
private void goButton_Click(object sender, EventArgs e)
{
    Navigate(toolStripTextBox1.Text);
}

// Navigates to the given URL if it is valid.
private void Navigate(String address)
{
    if (String.IsNullOrEmpty(address)) return;
    if (address.Equals("about:blank")) return;
    if (!address.StartsWith("http://") &&
        !address.StartsWith("https://"))
    {
        address = "http://" + address;
    }
    try
    {
        webBrowser1.Navigate(new Uri(address));
    }
    catch (System.UriFormatException)
    {
        return;
    }
}

// Updates the URL in TextBoxAddress upon navigation.
private void webBrowser1_Navigated(object sender,
    WebBrowserNavigatedEventArgs e)
{
    toolStripTextBox1.Text = webBrowser1.Url.ToString();
}

        Not address.StartsWith("https://") Then
        address = "http://" & address
    End If

    Try

Remarks

Note

For new Windows Forms projects, we recommend using the Microsoft Edge WebView2 control instead of the WebBrowser control.

The WebBrowser control lets you host Web pages and other browser-enabled documents in your Windows Forms applications. You can use the WebBrowser control, for example, to provide integrated HTML-based user assistance or Web browsing capabilities in your application. Additionally, you can use the WebBrowser control to add your existing Web-based controls to your Windows Forms client applications.

Important

The WebBrowser control is resource-intensive. To ensure that all resources are released in a timely fashion, call the Dispose() method when you're finished using the control. You must call the Dispose() method on the same thread that attached the events, which should always be the message or user-interface (UI) thread.

The WebBrowser control cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

The WebBrowser control has several properties, methods, and events related to navigation. The following members let you navigate the control to a specific URL, move backward and forward through the navigation history list, and load the home page and search page of the current user:

• Url
• Navigate
• GoBack
• GoForward
• GoHome
• GoSearch

If the navigation is unsuccessful, a page indicating the problem is displayed. Navigation with any of these members causes the Navigating, Navigated, and DocumentCompleted events to occur at different stages of navigation.

These and other members, such as the Stop and Refresh methods, let you implement user interface controls in your application similar to those in Internet Explorer. Some members are useful even when you don't want to display the WebBrowser control on your form. For example, you can use the Print method to print the latest version of a Web page without displaying the page to the user.

The WebBrowser control also lets you display content that you create in your application or you retrieve from a database or resource file. Use the DocumentText or DocumentStream property to get or set the contents of the current document as a string or data stream.

You can also manipulate the contents of a Web page through the Document property, which contains an HtmlDocument object that provides managed access to the HTML document object model (DOM) for the current page. This property is useful, when used in combination with the ObjectForScripting property, to implement two-way communication between your application code and dynamic HTML (DHTML) code in a Web page, letting you combine Web-based controls and Windows Forms controls in a single user interface. You can use the Document property to call scripting code methods from your application. Your scripting code can access your application through the window.external object, which is a built-in DOM object provided for host access, and which maps to the object that you specify for the ObjectForScripting property.

The WebBrowser control is a managed wrapper for the ActiveX WebBrowser control, and uses whichever version of the control is installed on the user's computer.

Note

• This class makes security demands at the class level. A SecurityException is thrown when a derived class or any caller in the call stack does not have full trust permission. For details about security demands, see Link Demands and Inheritance Demands.
• The WebBrowser class can only be used in threads set to single thread apartment (STA) mode. To use this class, ensure that your Main method is marked with the STAThreadAttribute attribute.
• For accessibility purposes, the TabStop property should be set to false when there is no content to display in the WebBrowser control. Change the value to true to enable users to navigate via keyboard into the contents of the control.
