WOW.NET is the most complete WebBrowser implementation available on the market. Now you can have all of the features of the original ActiveX WOW control you know and love but in a pure .NET assembly and a HUGE number of new features. Of course, we still have the original window.external.RaiseEvent functions, and you can set your own [ComVisible] .NET objects to be the window.external object so you can call your object's methods and properties directly from your webpage. The download includes examples.

WOW.NET is a C# .NET 2.0 control that creates, hosts and sinks the events of the original Webbrowser control (Not .NET or any other wrapper). Advanced customization and total control over the Webbrowser control are achieved via implementation of a number of interfaces, along with the addition of many methods, properties and events. The control has no dependencies on MSHTML interop. All of the interfaces, enums and structs are defined within the project.

Here are some of the features of this control:

Can easily be extended by adding other interfaces and methods, unlike .NET or any other Webbrowser wrapper
All the basics expected from a Webbrowser wrapper are implemented. Setting/getting UI, and DL control flags. Handling of context menus, keyboard, registry, security manager, script errors, popups, authentication, security problems, font size, message boxes
Stop dialogs launched using showModelessDialog() and showModalDialog() jаvascript methods
Monitor all HTTP and HTTPS request and response headers with the opportunity to add your own headers. This includes images, sounds, scripts, etc.
Built in HTMLDocument and HTMLWindow events
Frameset aware. All the relevant routines check for frames
Full drag and drop support
Refresh begin and end events
Create and resolve Internet shortcuts using IShellLink interface
Load HTML content specifying BaseURL
Added functionality to use the control as an MSHTML editor
MSHTML as a UI-less HTML parser helper class

Control

This is a basic class derived from Control class. It overrides a number of Control methods in order to create, host and dispose the Webbrowser control. In addition, it handles resize events and forwards keyboard, focus, refresh and visibility events to the hosted Webbrowser control.
Interfaces

Each interface mentioned below plays a role in either the hosting or customization process. I decided not to go through a detailed explanation of how to implement and use the interfaces. One can easily find all of the information regarding implementation and functionalities offered by these interfaces from MSDN, or right here on this site.

IOleClientSite - required as part of Webbrowser control hosting interfaces
IOleInPlaceSite - required as part of Webbrowser control hosting interfaces
IDocHostShowUI - to handle ::ShowMessage
IDocHostUIHandler - to handle ::ShowContextMenu, ::TranslateAccelerator, ::GetOptionKeyPath, ::GetDropTarget and ::GetHostInfo
DWebBrowserEvents2 - to handle Webbrowser events
IDropTarget - to handle full drag drop internally
IServiceProvider - to handle ::QueryService
IHttpSecurity - to handle HTTP-related security problems
IWindowForBindingUI - returns a handle via ::GetWindow that is used by MSHTML to display information in client UI
INewWindowManager - WinX sp2 and up, to handle popups
IAuthenticate - to handle basic and NTLM authentication
IOleCommandTarget - to intercept script errors via the ::Exec method
IinternetSecurityManager - to handle ::ProcessUrlAction
IHTMLEventCallBack - A callback mechanism to pass HTMLDocument and HTMLWindow events to the control and, in turn, to the client
IProtectFocus - IE7 + Vista - Queries for permission to grab the focus when loading the page or when a script attempts to focus an element
IHTMLOMWindowServices - XP sp2 - Enables applications that are hosting the WebBrowser Control to intercept the window object calls for manipulating the host window coordinates from Dynamic HTML (DHTML) script
