Transcript:
00:06 We need to create a WPF solution, reference the DotNetBrowser library using NuGet and add the license file. You can find detailed instructions in our previous tutorials.
00:16 MainWindow markup
00:19 Add the DockPanel and set the LastChildFill property value to ‘true’.
00:23 Add the StackPanel with horizontal orientation into the DockPanel and set its ‘DockPanel.Dock’ property value to ‘Top’.
Inside the StackPanel, create a TextBox named ‘RequestTextBox’ and set its width.
00:54 Next to the TextBox, create a button, set its name and text and create its ‘Click’ event handler.
01:16 Finally, add the WPFBrowserView to the DockPanel, set its name and the initial URL.
01:30 Implementing the MainWindow behaviour. Create the ‘CustomProtocolHandler’ class inherited from the ‘IProtocolHandler’ interface and generate the method stubs.
01:47 Go to the ‘Handle’ method. In this sample we will simply return the URL of the request as the response body. Return the new instance of the ‘UrlResponse’ class. Initialize this instance with the ‘request.Url’ property value transformed to a byte array.
The ‘UrlResponse’ class represents the response data which will be displayed by the Browser. The response data should be provided as a byte array.
02:12 Go to the main window constructor.
02:15 After calling the ‘InitializeComponent’ method, register the new instance of the ‘CustomProtocolHandler’ class as the protocol handler using the ‘Register’ method of the ‘ProtocolService’ class. This method requires the protocol name and the instance of the handler which will be associated with the specified protocol.
02:32 Finally, call the ‘LoadUrl’ method of the browser instance using the text from the ‘RequestTextBox’.
02:42 Now you can build and launch your application. As you can see, the http protocol of the initial URL is handled as usual - the browser instance loads the specified website. But if we specify the registered protocol, the registered handler is called and the browser displays the requested URL.
