public function GoBack() : boolean
Return Value
Type:
System..::.Boolean
true if the navigation succeeds; false if a previous page in the navigation history is not available.
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;
}
