HtmlWindow.Navigate Method (String)
Displays or downloads the new content located at the specified URL.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
If the url parameter points to an HTML page, the page currently displayed in the window will be destroyed and replaced with the new page; any references your application holds to managed DOM objects in the old page will not be valid. If url points to a resource that cannot be displayed by Internet Explorer, the user will be presented with a dialog box asking whether to open the resource outside of the application, save it to disk, or cancel the download operation.
