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 want to display HTML in my forms. The problem is I have to use a Boxlayout to place my components. So when I put a WebBrowser I'll have some height and scroll issues. I get the HTML I want to display from a webservice. The length of the content is variable. I just want to display a part of this response. Here is what I already have:
The webBrowser is below the edit button and ends near the LBL_LIB_NOM label.
As you can see the webBrowser is way too high and I can't scroll the Form when I click over the WebBrowser. In this example I would like to reduce the size of the WebBrowser so we can only see the Title. I also would like if possible to scroll my form when I click on the WebBrowser since I don't want the WebBrowser to scroll.
I have tried a few things to solve my issue:
I tried to override the calcPreferredSize method.
I revalidate my form and my webbrowser.
I resized it's container using the deprecated setPreferedSize method.
In that case the container is well sized but the the WebBrowser displays
above the other components.
The usual answer I have seen in other posts is to put the WebBrowser in a BorderLayout but I can't do that.
So here is my question: Is there any other component I can use to display one HTML line ? Or is there a way to make a webBrowser work properly in a boxLayout ? Do I have to write my own HTML renderer ?
I'm guessing you want box layout so you can scroll... This is problematic.
Web views generally expect to scroll themselves and this is common in native widgets which handle their own events and thus scrolling. It's hard for our code to know when your swipe is intended for us or to the underlying native widget and it's harder still to do this in a consistently portable way.
There are 3 options:
Use only Codename One code
Use a border layout or similar layout
Use the web browser for the entire UI of this form
If you want to take the first option this article might be useful as a starting point.
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 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.
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.
Is this possible?
I used a Frame control and:
show(ex:showwindow.xaml)
But I get this error:
root element is not valid for navigation
sure you can navigate (show) a window by using:
YourFrame.Navigate(YourWindow);
However I don't like much this multi-window approach, better create some user controls for segmenting your application.
It is more common to use the Page class with the Frame control. Windows, in WPF are the top level items, with their own titlebar, chrome etc. Also, the Page can tap into the NavigationService provide by the framework.
