Alternative HTML with Silverlight.CreateObject

Alexander Makarov — Wed, 25 Nov 2009 07:17:32 GMT

Hi!

When I use Silverlight.CreateObject function I don't want show usual "Get Microsoft Silverlight" image link to download Silverlight.

Instead of it I need to show my custom html, which is contained in parent element e.g.

    <div id="silverlightControlHost">
        <h1>Hello, world</h1>       
                <script type="text/javascript">
                    Silverlight.createObjectEx(
                    {
                        source: "ClientBin/Shell.xap",
                        parentElement: document.getElementById('silverlightControlHost'),
                        id: "sl4",
                        properties:
                        {
                            width: "100%",
                            height: "100%",
                            background: "white",
                            version: "3.0.40624.0",
                            enableHtmlAccess: "true",
                            isWindowless: "true",
                            inplaceInstallPrompt: false
                        },
                        events:
                        {
                            onError: onSilverlightError,
                            onLoad: null
                        }
                    });
                </script>       
    </div>

In this case I want to see "Hello, world" string.

I have loaded a silverlight control inside the below div. When i am trying to load a Pop-up (it is HTML pop-up), not of the Javascript. The pop-up is getting loaded, but behind this div.

Silverlight app z-index on html page

AlbireoYellow — Mon, 23 Nov 2009 09:47:15 GMT

Hi there!

I have to make a kind of banner from silverlight app. I'm trying to put a DIV (with a link in it) with high value of Z-Index to cover the app, so when user will click on app he or she will actually click on the div. But it's not working, because the app is always on top of the div...

Can I manage Z-Index of silverlight app, or can the problem ( adding a "redirect on click" to silverlight) be solved another way?

C# 4 and the 'dynamic' keyword

dcstraw — Thu, 28 May 2009 22:12:20 GMT

With the release of Visual Studio 2010 beta, has anyone heard about when we can expect support for C# 4 with Silverlight? Honestly the only thing that has me really interested in the 'dynamic' keyword of C# 4 is the possibility of trivial integration between Silverlight and javascript. I'm hoping this will come with a later release of SL3, presumably when the core CLR 4 is ready.

FWIW right now if I try to call a function dynamically in SL3, I get the error:
One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?

Silverlight and Scanning (Via TWAIN using Java Applet?)

kd100 — Fri, 06 Nov 2009 00:34:15 GMT

I am creating a Silverlight application that needs to communicate with a scanner (using TWAIN drivers). I know Silverlight cannot do this directly, and I will need to use Java to interact with the scanner. I don't want to use ActiveX because I need it to run on Macs and Linux machines.

So my question is, can I get a java applet to pass a scanned file to a Silverlight application? Is this done using web services? javascript? Can anyone confirm that this is is possible and maybe point me at some information regarding how it could be done?

Closing the Session via javascript ??

aviad.dror — Wed, 11 Nov 2009 07:36:49 GMT

I'm writing a Silverlight application that is hosted in a virtual directory on the IIS server. The application contains an aspx page that loads the Silverlight object when surfing to the aspx page. My problem is that although I set the virtual directory authentication to Basic mode, I have a strange scenario where the logon form does not pop up whe browsing to my web site. The scenario is the following:

1. I open my IE on its home page.

2. I browse to my Silverlight application

3. The logon of ISS is pop up, I type in my user and password (I’m in a domain)

4. I’m in the application web site.

5. Now I browse out of the web site to another web site, for example, yahoo.com

6. Now I retype my Silverlight web site application address at the http line

7. I got no logon process and I’m in with the previous credential even though I didn’t actually logged on.

I think that the problem is that the application session is not ended in the right way and the credencials are saved as some cockies and therefore then is no logon in the second time. How can I solve it?

Thanks,

Aviad

determine when silverlight plug-in loses/gets focus

owlex17 — Tue, 10 Nov 2009 19:09:44 GMT

Is there any way to know when the plug in does not have the browser's focus? I noticed that even if you click outside of the plug-in, the same element still has the silverlight focus.

example: we have an override on the browser's right click event that pops up a custom context menu. When clicking a certain function in the menu, I need to know whether a certain field in the plug-in has focus, or if this function is being invoked from outside of the plug-in.

Calling a js function that is not in testpage.aspx from silverlight

something relevant — Wed, 11 Nov 2009 12:08:33 GMT

Hi,

Could someone tell me how to call a javascript function(defined in an aspx page that is NOT testpage.aspx or testpage.html) from silverlight code-behind. When I use HtmlPage.Window.Invoke("LoadFromSilverlight", "Hello world");

I get an exception saying "Failed to invoke LoadFromSilverlight".

The aspx page that contains the js func has a uri like

http://localhost:54487/folder1/folder2/Form.aspx.

How do I specify this Uri?

Any help would be appreciated.

lblTest is a Label on my page. I want to change the text of that label as shown in GetCallbackResult() method. But if I change it, it will not display.
I know it can do from javascript. But I wont to do it in code behind. Is there any way to do it.

Best way to hide Silverlight control

Erick T — Sat, 31 Oct 2009 22:26:20 GMT

I have a situation where there is a div that will contain either a Silverlight control or some HTML. The Silverlight control is the navigation, and the HTML contains the details. For background, the application is a ASP.NET MVC application.

My first thought is to have two child divs, one with the HTML content, one with the Silverlight content, then write a little JS to hide/show the correct one. This works fine, but I am wondering if it is the best way. What should I do to the Silverlight control before _hiding_ it so that it won't use any more resources than needed? What should I do before showing the Silverlight again so that the user is up and running quickly?

If this example doesn't make sense, I can put together a simple repo.

Thanks!

Erick

User Authentication

silverlightmonster — Sat, 31 Oct 2009 21:50:52 GMT

Hi,

I am creating a silverlight application. I selected a Business Application from the silverlight menu when creating the project and am using the built in login features.

Now, what I wish to do is the following:

I have certain pages which are reserved only to logged in members. However, at the moment I can access them even when I am not logged in. Can anyone tell me how I can redirect the user to the login page if he is not logged in when trying to access such pages?

Please help. I am using VB.Net as code behind an am relatively newbie in these things..

Thanks

Visibility animation

johndd — Thu, 20 Dec 2007 17:23:19 GMT

Is there (or please could there be in future versions) a way to animate the visibility of an element?

Setting visibility to collapsed is recommended practice for improving performance of silverlight applications. As a work around at the moment I'm getting the event for the end of the storyboard and using this to set Visibility = Collapsed on critical items that have had opacity set to 0, and setting Visibility=Visible before the storyboard that makes them visible again. The ability to set visibility in a storyboard would improve separation between the design and the code.

Thanks,
John.

Where is AudioStreamIndex set???

sensamecca — Tue, 18 Dec 2007 21:52:37 GMT

I'm working with some Silverlight examples and we've got it displaying an encoding session just fine. I was curious where we would set the AudioStreamIndex property. It seems to reference a MediaElement object, but I don't see one specifically in the code. We have a player, etc.

We want bi-lingual support in our player and that means referencing either AudioStreamIndex 1 or AudioStreamIndex 2 in our .js (or XML?) files. This code we are using is a sample that's been slightly modified. Does anyone have a JS example of how and where to use this AudioStreamIndex value?
