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,
-Tom
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.

Taking it a bit further than hosting WinForms user controls in my WPF application, I am actually hosting Delphi forms, i.e. top level windows. I am doing so through the voodoo in blog post How To Host Top-Level HWNDs In WPF.
Nearly everything works perfectly. I send a COM server, built in Delphi, a menu path string, and it sends back a window handle, which I pass to the host control described in the blog. The Delphi window receives nearly all events (rather, Windows Messages) correctly, without any intervention on my part.
The only problem is the buttons. They receive a click event/message fine, and work, but now the Delphi guys have added new icons to the buttons, and each button has an active icon, a hover icon, and a click icon. They receive none of the messages they should to change these icons. Why do nearly all messages work except these? What can I read and or do to try and correct this?
In MouseOver event, send some user message and catch it.

HWNDs inside WPF > Notable Differences in Input behavior
While the mouse is over the HwndHost, your application does not receive WPF mouse events, and the value of the WPF property IsMouseOver will be false.
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!
My WPF app has a window with various text boxes and a WebBrowser control.
The WebBrower control is used to show a web site (I doesn't own) and then a Login button in the WPF window fills the fields in the site from the text boxes.
The problem is that the web site calls focus() method on one of its input fields on load, and that still the focus from the text box in my WPF window. I want the focus to be on the WPF window field and not in the web page within the WebBrowser control.
I tryed calling MyTextBox.Focus() in the WebBrowser's LoadCompleted event, but to no avail. Setting the WebBrowser's IsEnabled or even Visibility properties didn't help either.
Does anyone have an idea how I can overcome this and move the focus to the WPF control instead of the web page input field?
Don't think you can extend the control site to add IProtectFocus to the site. Try interop the Windows Forms version of the webbrowser control and override the CreateWebBrowserSiteBase method to provide your own control site.
I have the following desired workflow: on HTML button click a Silverlight modal popup (dialog) must be displayed. No Silverlight content is displayed before HTML button click and no Silverlight content must be displayed after exiting from modal SL popup.
According to our customer inclination we couldn't use another technology for such popups.
Any thoughts on how to accomplish mentioned workflow?
I'm quite new to Silverlight so all the ideas are highly appreciated.
The requirement is a little unusual, but here goes...
I am assuming you have a Silverlight test project and know enough HTML/JScript to popup a window, as you tagged this question as Silverlight only.
Think of Silverlight as just another component you can put on a web page. Any web page. It can be a small control, or fill a HTML window.
In your case you want to simply put your Silverlight startup code into a html page that a popup window can show. The popup window will be triggered by JScript attached to a button.
The Silverlight startup code is usually generated for you in a HTML test webpage in your Silverlight Webproject. Copy it from there.
If you need more detailed instructions for a specific example, please provide more detail.
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
