How can I embed a demonstration applet written in Silverlight within a blog post? Is it possible to do so using any hosted blog engines, or only using a blog engine that I host myself?
I assume that I will need to use the same tags and .js as in a regular (X)HTML page with a SL control. Are there any hosted blog engines that will permit me to enter this? (Is it possible with blogger?)
Does the SL security model mean that the XAP file need to be hosted on the same site as the blog pages itself?
You can host a Silverlight app in HTML using the <object> tag, there is no need for the blog host to understand any of this. There is no server side element to hosting a Silverlight app its a purely client side thing.
<object id="SL" data="data:application/x-silverlight-2," type="application/x-silverlight-2" style="width:400px; height:300px">
<param name="source" value="MySLApp.xap" />
<param name="minRuntimeVersion" value="3.0.40624.0 />
<param name="initParams" value="someParam=value" />
<a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;">
<img src="http://go.microsoft.com/fwlink/?LinkId=108181" style="border-style: none" alt="Get Microsoft Silverlight" />
</a>
</object>
In this case the Silverlight app "MySLApp.xap" is placed in the same folder as the HTML page using it. However it could be on a different server if you like. However access to the HTML Bridge will be blocked but then if your app is self contained and does not need to communicate with the host page then there is no problem.
I created a Silverlight xap to host hero images OR video in my wordpress theme - I pass the content to it using initparams and custom fields per post.
That way I can use the same xap to host videos with media controls if appropriate or images with cool fade ins/click effects
example image post:

example video post (click vid for controls):
http://www.blackspike.com/site/wpf/hanselmans-babysmash
Both using the same xap!
An easy solution that worked for me is just to use an iFrame. So I published the regular TestPage.html generated by Visual Studio to my web site (along with the .XAP file of course) and then embedded it:
<iframe src="http://www.lostbearlabs.com/sl/Spring001/TestPage.html" frameborder="0" width="400" height="400" scrolling="no" ></iframe>
Using blogger, I discovered this gotcha: Any attempt to make the HTML pretty (e.g. by splitting it into separate lines) causes blogger to insert spurious <br> tags into the output, even if I do my edits using the "Edit HTML" view. So the iFrame tag must all be on a single line!!
You might want to check your host has the required MIME types mapped:
http://learn.iis.net/page.aspx/262/configuring-iis-for-silverlight-applications/
according to this Server 2008 IIS7 should work out of the box but IIS6 may require MIME types adding...
The solution marked as answer above works well if the HTML page and the Silverlight xap file are hosted on the same server.
As this is not possible in most of the cases, as most of the bloggers use either blogger/WordPress. We do not have any way of setting the mime type on these hosting providers.
Here is a good link which explains in detail regarding hosting an Silverlight application in blogger.

html:
<div id=“file”>
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2">
...
</object>
</div>
I've manage to click the silverlight button using following code:
f = Browser.div(:id => "file")
Browser.driver.action.move_to(f.wd).click.perform
However, when the file upload dialog opens, how can I set the file?
I'm using ChromeDriver.
According to the documentation, watir-webdriver cannot interact with silverlight objects:
Watir will drive web applications that are served up as HTML pages in a web browser. Watir will not work with ActiveX plugin components, Java Applets, Macromedia Flash, or other plugin applications. To determine whether Watir can be used to automate a part of a web application, right click on the object and see if the View Source menu option is available. If you can view the HTML source, that object can be automated using Watir.
Having clients over the globe, we encountered some serious loading delays for initially retrieving the XAP from various locations. The hope was that we could host the compiled XAP in the cloud, offering a closer download depending on the end-user's location.
We are using RIA services, but the service endpoints need to remain on our local server, because of data connections, connections to internal services, etc.
How do we distribute the XAP using cloud-based services, while having it continue to function the same as it does currently?
EDIT: Since I worked through this and found the answer myself, I've moved the steps that I had accomplished before out of my question and into the answer to better facilitate a good Q&A format and for anyone else approaching the problem from step zero.
After hammering away at this, I found the solution to get it almost completely working.
Update RIA service endpoints with absolute URIs to refer back to the hosting page rather than relative to the XAP location itself.
Ensure all image (etc.) content is loaded from either resources in the XAP or else ensure they are uploaded as well to the Azure Storage Blob. Any relative paths will try to resolve to the XAP location.
Generate the XAP file and upload to the Azure Storage Blob. You will need to ensure that the XAP has Content-Type of application/x-silverlight-app. I accomplished this using Azure Storage Explorer. You can set Content-Type by opening the properties of the item via double-click, but, and even better, you can click the Settings gear to 'Edit Content Types' and add a rule that .xap is application/x-silverlight-app so that it will be automatically set any time you upload.
Ensure you have a proper cross domain policy in place.
Update your hosting page to supply the new source. Additionally, you will need to add the enablehtmlaccess param if not already set, since this value is false by default for cross domain.
For item #1, I accomplished using code such as the following:
var u = HtmlPage.Document.DocumentUri;
Site = u.AbsoluteUri.Substring(0, u.AbsoluteUri.LastIndexOf('/'));
MyServiceUri = new Uri(Site + "/ClientBin/My-Namespace-MyService.svc", UriKind.Absolute);
For item #4, my code looked like:
<param name="source" value="<%= Request.Url.Scheme %>://mytest.blob.core.windows.net/my-container/MySilverlightApp.xap"/>
<param name="enablehtmlaccess" value="true" />
One last thing to note: If using a custom splash screen, then figure out how to get this to work. I don't know how. What I have found out is that if you set splashscreensource as the location of a .xaml file, then it simply does not load. It will just show the basic silverlight load percent screen, which does at least seem to report load % correctly. In order to get the custom splash screen to load, it seems to only work when included inline. You can do this via:
<script id="xamlSplash" type="text/xaml">
<%= System.IO.File.ReadAllText(Context.Server.MapPath("~/Loading.xaml")) %>
</script>
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<param name="splashscreensource" value="#xamlSplash" />
However, while this will show the custom splash screen, it will not work if you have any progress report on the splash screen. The javascript function referenced by onsourcedownloadprogresschanged will never fire. I could not find why this was the case, nor a way around it. You'll just have to have a spinning animation or the like in place of an actual % progress indicator.
Good Morning,
I am new to sharepoint but I am pretty salty as far as silverlight goes. I know on a standard silverlight application hosted inside an ASP.NET app you can simply append .xap? here to make sure the xap files does not cache each time. In SharePoint I found only one article that even came close to exphttp://techblog.m-dd.com/index.php/2013/01/25/resolve-sharepoint-silverlight-webpart-caching-problem/. When I trying to Edit the WebPart and Under Application, provide path to .xap I click Configure. I then appent something like this to the end of the xap file: .xap?ver=1.1.1.0002 and recieve the following error in sharepoint: Cannot save all of the property settings for the Web Part. One or more errors have occured.
Any help would be greatly appricated.
Thanks
In my experience I've had a lot more luck by using a Content Editor Web Part and then embedding the tag which then links to the .xap file from there. Essentially you can edit the HTML source of the page by adding such a web part.
In the Content Editor Web Part, select "Edit Source" and paste something similar to this:
<object width="300" height="300"
data="data:application/x-silverlight-2,"
type="application/x-silverlight-2" >
<param name="source" value="/Library/YourSilverlight.xap?v=1"/>
</object>
See embedding Silverlight here: http://tz.nu/1o9pkSk
See more about adding the Content Editor Web Part here: http://tz.nu/1tSCOnJ
Using this approach, you can simply modify the page and edit the CEWP (Content Editor Web Part) and append the querystring behind the .xap to something unique (in my case, perhaps increment it to YourSilverlight.xap?v=2).
As an alternative to all of the above;
I've oftentimes developed my own base web part which hosts Silverlight .xap files, then I'll deploy and add that Web Part instead. I've often built-in the functionality for updated versions into the code so you never have to do that manually, but that's another story.
I am experimenting with Silverlight (4.0) Navigation and deep linking. The problem I'm facing now is that my Silverlight application is hosted inside a MVC view page (.cshtml) as shown below, which is fairly standard.
<object id="SilverlightAdvanceAdminObject" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<!-- omitted for brevity -->
</object>
At this stage, my URI is routed by MVC, so I would have a Admin controller which has a Advanced action which in turn returns the above view.
eg. http://localhost/Admin/Advanced
From here on out, I would like MVC to allow me to perform a Silverlight Navigation to 'deep link' into a view inside my SL app.
eg. http://localhost/Admin/Advanced#/Users
Uri Mapper:
<sdk:Frame region:RegionManager.RegionName="MainRegion">
<sdk:Frame.ContentLoader>
<prism:FrameContentLoader RegionName="MainRegion" />
</sdk:Frame.ContentLoader>
<sdk:Frame.UriMapper>
<sdk:UriMapper>
<sdk:UriMapping Uri="" MappedUri="/UserAdminView" />
<sdk:UriMapping Uri="/{viewName}" MappedUri="/{viewName}" />
</sdk:UriMapper>
</sdk:Frame.UriMapper>
</sdk:Frame>
The above example is something I would like to achieve, where the Users component of the URI is a view inside my SL application which is managed by a UriMapper. At the moment, this doesn't seem to work.
Any thoughts?
I would usually wait for an answer, but I found this problem to be a bit of a lemon. For the Silverlight applicaiton to receive the URI routes, you need to a an iframe with a specific id into the page hosting the SL.
<iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe>
I have no idea why this is not mentioned anywhere that can be easily seen, but apparently missed because if you use the Silveright Navigation project template, this would have been added for you automatically.
Good one MS! =.=
How do I add a XAML file to an ASP.NET web page?
Use the Silverlight control:-
<object type="application/x-silverlight" width="100%" height="100%" id="slc">
<param name="source" value="/myfolder/myfile.xaml"/>
</object>
Depends on what you want to do with that XAML file. :-)
If you want to use it with Silverlight, you need to learn how to write SL applications.
If you want to generate a static picture from the XAML to send to the client, you can look at this blog post.
