I wouldlike to embed a webbrowser in a WPF application. The browser should look like a normal browser, with address bar, back and forward button and status bar. Is there a way how that could easily written in XAML, with a direct databinding of the address to a textbox, with a direct routing of events from the buttons to the webbrowser object, and the enabling back?
Why not?
Here and here are uploaded some screenshots from our application which has WebModule inside and is able to work like browser.
In our implementation we used Windows Forms WebBrowser control as browser engine and MVVM as communication pattern. Model has navigation commands (forward, back, ...) that raise proper events. View is handling this events and delegate requested actions to inner WebBrowser component. Additionally view is handling WebBrowser's events (NewWindow, DocumentCompleted, Navigating, Navigated) and setting up model's state.
Model and view together contain about 500 lines of code (I don't think it's very much, do you?).
Of course, I should mention, that due to using IE engine this browser could have some problems on complicated web-sites.
P.S. We didn't use System.Windows.Controls.WebBrowser because it does not provide access to NewWindow event.
P.P.S. I've posted this answer from browser in our WPF application. Good luck!

I am really new to Silverlight. I am working through some of the sample codes I found online.
I notices sometimes a new "Page" is added, and sometimes a new "User Control" is added.What are the differences between those 2?
Btw, when I tried specifying the URL for a hyperlink as "www.apple.com", there is an error saying "www.apple.com" can not be found. Are there anyway of specifying an URL for a website for a HyperlinkButton?
Thanks :)
In SL3 and up; a Page correlates to the Navigation framework whereas a UserControl is a control providing a defined set of functionality using multiple controls which can then be used within a Page.
User Control:
When you build your project , any user control that you created will appear in the toolbox also. You can drag and drop it like any other control (like a button or a grid).User controls are used for enhanced flexibility. You can customize your controls, set as many properties you want , and it really simplifies things without going for creating custom controls.
Page:
However, when you come to a Page, you can use it mostly for Navigation . It can contain other controls , but it is mainly intended for Navigation within Frames.
I see methods for GoBack, GoForward, Refresh, and Navigate, but no "Stop" or "Cancel". How do I do it?
Use can use the InvokeScript method over WebBrowser control to stop page navigation.
yourWebBrowser.InvokeScript("eval", "document.execCommand('Stop');");
Looks like it is a bit tricky you should get IWebBrowser2 interface from the WPF WebBrowser control, after that you may get access to some methods that not publicly exposed in this control.

I have a hopefully trivial question. Currently, my company works with a rather obscure language (SyngergyDE) and we need to call a SilverLight application inside our product. Unfortunately, this obscure 3rd party language only (currently) supports the opening of WPF screens. So with that said, I thought I'd develop a small WPF user control that contains a "WebBrowser" control and navigate to the silverlight application's URI. This works fine, and I'm able to see the SL application. Here is my question - we have a "Close" button on the SL application, and when users "Click" that button, we want the window to close.
Does anyone have any suggestions on how we can communicate the "Closing of the SL App" to the WPF user control, so that the entire WPF user control closes as well?
Thanks everyone,

Attach an event handler to the WebBrowser.Navigated event.
Have the close button in the Silverlight application use:-
HtmlPage.Window.Navigate(new Uri("about:blank", UriKind.Absolute));
When the Navigated event fires in WPF with the url "about:blank" then its time to close the control.
Use Javascript and the HTML DOM as the glue here.
For example, when the SL app close button is clicked, have Silverlight trigger some Javascript code that sets a flag, or alternately, raises some HTML document event.
The WPF control could poll that flag in the HTML + Javascript, or alternately listen for that HTML document event, then close the user control.
I would like place a silverlight contol on an HTML page --- something about the size of a typical calendar control. However when the user selects a day on the control a bigger canvas opens up on top of the containing page --- something like a modal dialog box that you might find with the AJAX.
I'm wondering if this is even possible with Silverlight, or is the silverlight content limited in size to the DIV element on the host page?
UPDATE: after doing some poking around, I think the answer will involve using the ChildWindow control introduced with Silverlight 3. However I'm still at a loss how to have the ChildWindow display ontop of the existing content
I know one way, you will need javascript event on the page itself to expand a silverlight object to fit the whole page then build you silverlight event accordingly.
I have a WPF application which contains a WebBrowser control.
Currently, the user can select something within the WebBrowser and can copy the content by dragging it out to another application and dropping it there.
I'd like to be able to stop the user doing this. I'd assumed that there would be a "DragStart" event that I could capture and cancel - but I haven't been able to find something so simple.
Is it possible to capture the start of drag event and cancel it?
Is there a better way to achieve this?
You can implement IDocHostUIHandler::FilterDataObject and filter out common clipboard formats
You don't get access the WPF browser's native interface until the document is ready. Not sure if it would work with the WPF browser class. There is also a bug in Windows Forms to prevent you from customizing its implementation of IDocHostUIHandler.
You can try some wrapper class of the webbrowser ActiveX, such as the one described at http://www.codeproject.com/KB/miscctrl/csEXWB.aspx
