Navigates the System.Windows.Forms.WebBrowser control to the previous page in the navigation history, if one is available.
true if the navigation succeeds; false if a previous page in the navigation history is not available.
The System.Windows.Forms.WebBrowser control maintains a history list of all the Web pages visited during a browsing session. You can use the WebBrowser.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 WebBrowser.CanGoBack property to determine whether the navigation history is available and contains a previous page. Handle the WebBrowser.CanGoBackChanged event to receive a notification when the WebBrowser.CanGoBack property value changes. Handling this event is useful, for example, to change the enabled state of a Back button when the System.Windows.Forms.WebBrowser control navigates to or leaves the beginning of the navigation history.
