I want to show the result of a WebClient-Postback in an new Browser-Popup-Window. As the "Navigate" and "Popup" methods of HtmlPage only support Get-requests, I issued an POST-request to an REST-Service via WebClient. But now I want to show the result (e.g. application/ms-excel or application/pdf) in an new Browser-Window.
Therefore, can I open an new BrowserWindow and set its contents as well as some corresponding http-headers with on-board means of Silverlight 4? Or even better, is an easier way to trigger the browser to do the POST-request to the service?
Best Regards
I tried going this route but the WebBrowser control is not opened to the developer. What I did as a temporary workaround was to open my webpage http://www.xyz.com/default.aspx inside the WebControl and let the page drive the rest.
Mike Taulty had an example for somthing like this, how you can use javascript to communicate back to the silverlight app through InvokeScript:

I hope it helps!

I'd like to use the Notification API to create toast notifications for a Silverlight app designed to run both in and out of the browser, but the NotificationWindow class is only available OOB.
Does there exist anything that can replicate the behaviour inside the app? My idea is to have a container in the bottom right of the screen overlaying all other content. Then, create a wrapper which detects OOB-mode, passing params to the Notification API if possible, or populating and showing my own container if not. Is there anything that does this available?
It seems strange that MS chose not to implement something like this, as has been pointed out before.
Displaying a notification in browser is simple. You just need to use a popup and make it appear in the right place. See the following post as an example.
Now the difference with that approach is that the notification will show inside the browser. In OOB it shows outside the window and it's visible even if the windows is minimized. Due to security reasons it's not possible to directly do this.
Out of interest, Chrome Applications like Tweetdeck and Gmail, are able to display notifications outside of the browser. I think this might be a possiblity, but not exactly a Silverlight and cross browser solution.
This might not be possible but I thought I'd check with everyone.
Is it possible to load a WebBrowserTask on WP7 but to have the url entry box collapsed? I'd also like to set IsHitVisble to false?
The reason I want to do this is to load a url (through databinding) but ensure that the user can't browse to other links on the page. I also need to keep the phones share control in the tool bar so I can't just use a webbrowser control and set the source to the url.
Does anyone have any ideas?
Not possible. You can use a WebBrowserControl inside your own app, but it's not recommended.
Basically such odd/weird limitations as this, don't belong in any modern day craftsmanship. And thus why it isn't a possibility (thanks Microsoft!)
I'm developing a Windows Application in C sharp.using a Web Browser control to Login to the Https Site and Download the List of files. I'm able to login in to the Site and I'm able to Navigate to the Page where files are listed to be downloaded. When I try Downloading the file using the file URL and trying to Navigate using Web Browser Control a Pop - Up appears asking whether to Open or Save or cancel. How to handle this Pop up and I'm stuck here.
Any Answers are appreciated.
Thanks,
Vinay.
If all you are trying to do is download a file, you might be better off using webRequest.Create("Url") instead of the WebBrowser control. There are ways of handling authentication depending on the method the website uses.
It's best not to use the WebBrowser to download files (unless initiated by the user, who can click the save button). Instead, you can use a WebRequest to download the files from your application.
Since you said you have to log in to the website, I'm going to assume that it uses the popular method of using cookies (as opposed to HTTP Basic Auth). To get the cookies from the WebBrowser, you can use the Cookie property of the WebBrowser's Document property.
I'm looking for something similar to the VB6 / .Net Winforms "Browser Control", that let's you show a browser inside your application.
I don't want to just render a page, I want it to be a fully-functional browser, in which people can click links, will run Javascript, etc.
In essence, what I want is an IFrame, only that it runs inside a Flash app, or a Silverlight app.
The ultimate reason for this is that I want to defeat IFrame busters. I'm making a web app that lets you see other sites inside of it, and I'm running into a bunch of sites that have this code:
var t=top.location,w=window.location;if(t!=w) t.replace(w);
(that's from eBay BTW)
which essentially pops the user out of my site and into theirs.
My hope is that by using a "browser control" of some sort, inside a plugin sandbox, "top", will be top for that browser control, and not for my site.
Of course, if you have any other ideas to achieve the same, they'll be more than welcome.
Edit: I've tried the Component One control suggested by Bill, but it didn't work for these purposes, because it's creating an IFrame outside of the SilverLight control, so it executes in the same context as the page hosting Silverlight, which is what I'm trying to avoid.
Northcode SWF Studio allows you to add browser window on the stage in Flash. I personally use SWF Studio as a third party SWF2EXE tool to extend the power of Flash projectors. It's quite stable and powerful. As far as browser control is concerned here is the example you can download and test if it serves your purpose. Check the Browser APT here.
We've not built a component to enable folks to do this but we're open to suggestions here. That being said, easiest solution is an iFrame, but word of caution in that when you overlay an iFrame over the the top of Silverlight we've seen customers experience perf issues as a result (mostly due to alpha transparency of the iframe etc).
This isn't isolated to Silverlight, Flash suffers the same issue as it has to do with browsers and rendering within the given operating system.

I use the HTML control created by Component One. It has the limitation that the Silverlight object in the page should be set to windowless, but otherwise it works very well.
It's an old post but I'll add my tupence answer. I used the DivElements free control for Silverlight link text and it works quite nicely. It just positions the div accurately so that it looks like it's on top.
As for the other such controls, you've got to set the windowless property of the Silverlight container to true.
It works really well for me and I'm able to seemlessly have Google maps and the Acrobat plugin displayed side by side with my Silverlight application.
PS: because the component just adds a <div> to the page, you can't do stuff like having it load dynamically Javascript file like in the <header> tag.
PPS: when setting the HTML code "by hand", be sure to hook up on the DocumentReady or Loaded event before playing with the HTML DOM.
Hope that helps someone.
I'm making a silverlight app that when the user does a mouse-over some tab bars, he/she will see a preview of the page it will link to. The reason for this preview is that just having a visual miniature of the page is often enough to make the desicion for the user. How do I in Silverlight make a control that simply displays a webpage, preferably scaled down?
Cheers

As you are probably aware, there are some issues relating to crossing domain boundaries in Silverlight. Issues that have been discussed on stack overflow for example.
This is relevant because generally you can't request web resources in other domains which you'd need to do here.
One way I've seen to get around this is to use a web service that doesn't have the same limitation. So you can create a web service that exposes a byte[] of the image and have the web service do the calls to retrieve the image and send it back to Silverlight.
Once you've got the image byte[] you can read that in an asynchronous call, and set the image source like this.
BitmapImage thumb;
using (MemoryStream stream = new MemoryStream(imgArray))
{
thumb = new BitmapImage();
thumb.SetSource(stream);
}
The other issue is how to generate the thumbnail, for that you can google, there are some projects that show you how and some public web services that do it for you. Amazon's is one such example.
