The WebBrowser control maintains a history list of all the Web pages visited during a browsing session. You can use the GoBack method to implement a Back button similar to the one in Internet Explorer, which will allow your users to return to a previous page in the navigation history.

Use the CanGoBack property to determine whether the navigation history is available and contains a previous page. Handle the CanGoBackChanged event to receive a notification when the CanGoBack property value changes. Handling this event is useful, for example, to change the enabled state of a Back button when the WebBrowser control navigates to or leaves the beginning of the navigation history.

The following code example demonstrates how to use the GoBack method to implement a Back button for the WebBrowser control similar to the one in Internet Explorer. This example requires that your form contains a WebBrowser control called webBrowser1 and a Button control called backButton.

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

' Navigates webBrowser1 to the previous page in the history.
Private Sub backButton_Click( _
    ByVal sender As Object, ByVal e As EventArgs) _
    Handles backButton.Click

    webBrowser1.GoBack()

End Sub

' Disables the Back button at the beginning of the navigation history.
Private Sub webBrowser1_CanGoBackChanged( _
    ByVal sender As Object, ByVal e As EventArgs) _
    Handles webBrowser1.CanGoBackChanged

    backButton.Enabled = webBrowser1.CanGoBack

End Sub

// Navigates webBrowser1 to the previous page in the history.
private void backButton_Click(object sender, EventArgs e)
{
    webBrowser1.GoBack();
}

// Disables the Back button at the beginning of the navigation history.
private void webBrowser1_CanGoBackChanged(object sender, EventArgs e)
{
    backButton.Enabled = webBrowser1.CanGoBack;
}

// Navigates WebBrowser1 to the previous page in the history.
void backButton_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   this->WebBrowser1->GoBack();
}

// Disables the Back button at the beginning of the navigation history.
void WebBrowser1_CanGoBackChanged( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   this->backButton->Enabled = this->WebBrowser1->CanGoBack;
}
