Silverlight 6 Hosting Romania - :: How to Create Storyboard Animation using Expression Blend in Silverlight

clock June 30, 2015 06:11 by author Rebecca

There are two ways to animate in Silverlight, through storyboards and through code. Expression Blend offers extensive help in creating storyboard animations. Silverlight animation is time based not frame based, this means that your animation will benefit from running at the maximum frame rate that the users machine will allow. Multiple storyboards can be created and run at the same time, but for the purpose of this basic tutorial, you'll be shown how to create a single storyboard.

Follow these simple steps to create storyboard animation using expression blend in Silverlight:

Step 1

To create a new storyboard, go to the Objects and Timeline tab then click on the ‘plus’ icon.

If you are using the default UI layout in Blend, you may want to hit the ‘F6‘ key to switch the layout from design mode to animation mode, this will give you a better layout for working with storyboards.

Notice that after adding a storyboard a red circle will be displayed in the top right of the screen, this indicates that you are in record mode. When in record mode, every change you make is treated as an animation and will be tied to a Keyframe. To turn record mode on or off click on the red circle in the top right of the screen, it should toggle from red to grey.

Step 2

For the purpose of this tutorial I have created a ball graphic and a shadow graphic as shown below. You can use any objects thay you like to make your own animation project.  I have placed them off the page to the left so that they start out of site.

Step 3

Storyboard animation is based on Keyframes set to specific times. To add a Keyframe, go back to the ‘Objects and Timeline‘ tab, select the objects that you want to animate and click the Record Keyframe button as highlighted below. You will see that a new Keyframe is added by each object at zero seconds.

Step 4

To add a Keyframe at a specific point along your timeline, drag the yellow time bar to the required point and then hit the Record Keyframe button. To make our ball graphic animate I have selected a time stamp of 0.5 seconds and moved the ball to the position shown below:

Step 5

Then you can animate the ball and shadow graphics again at 1 second.

And once more at 1.5 seconds to finish the animation.

Step 6

Now that we have completed the animation we may want to loop it multiple times or loop it forever. To make the animation loop, make sure you have the storyboard selected under the ‘Objects and Timeline‘ tab, then go to your ‘Properties‘ tab and scroll down to the ‘Common Properties‘ section. Here you have an option to repeat the animation several times, for this tutorial, you have to set it to ‘Forever‘.

Step 7

Finally, you need to tell the storyboard to play. Sometimes you will need a storyboard to be called by the code behind file, but you can use ‘Behaviors’ to start a storyboard instead. ‘Behaviors’ are pre-set actions that can be dropped onto objects in Blend, they are an easy way to achieve functionality without requiring knowledge of C# or alternative languages. To tell the storyboard to autoplay, go to the ‘Assets‘ button on the main tool bar (the last icon), select ‘Behaviors‘ from the list on the left to bring up the selection of behaviors. Find the behavior titled ‘ControlStoryboardAction‘ and drag it onto your ‘LayoutRoot‘. See how the behavior is indented below the ‘LayoutRoot‘. Select the behavior and go to the ‘Properties‘ tab, scroll down to the ‘Triggers‘ section and set the following settings:

EventName = Loaded

ControlStoryboard… = Play

Storyboard = Storyboard1 (the name of your storyboard)

You are done with your storyboard animation! Silverlight 6 Hosting is European Windows Hosting Provider which focuses on Windows Platform only.

Silverlight 5 Hosting France - :: How to Use Silverlight to Run an Elevated Trust Applications

clock June 23, 2015 06:39 by author Rebecca

In this article, you will see how to run an Elevated Trust Application within the Browser using Silverlight 5 Beta. For this demonstration, you will first create a Silverlight application by using Visual Studio 2010 with Silverlight Version 5.

Step 1

We will rename the application as 'TrustedAppsInBrowser' as shown below:

Step 2

Make sure you choose Silverlight version 5.0. Now let's add a reference of a API 'Microsoft.CSharp.dll' to our Silverlight application. Browse this API from the path 'C:\Program Files (x86)\Microsoft SDKs\Silverlight\v4.0\Libraries\Client'. Then, design the MainPage.xaml. and replace <Grid></Grid> with following code:

<Grid x:Name="LayoutRoot" Background="Black">         <Grid.RowDefinitions>             <RowDefinition Height="44*" />             <RowDefinition Height="44*" />             <RowDefinition Height="44*" />             <RowDefinition Height="170*" />         </Grid.RowDefinitions>         <StackPanel Orientation="Horizontal" Grid.Row="0">             <TextBlock Text="TO - :" Foreground="Yellow" FontSize="14"         HorizontalAlignment="Center" VerticalAlignment="Center"/>             <TextBox x:Name="txtTO" Width="350" Height="30"/>         </StackPanel>         <StackPanel Orientation="Horizontal" Grid.Row="1">             <TextBlock Text="CC - :" Foreground="Yellow" FontSize="14"         HorizontalAlignment="Center" VerticalAlignment="Center"/>             <TextBox x:Name="txtCC" Width="350" Height="30"/>         </StackPanel>         <StackPanel Orientation="Horizontal" Grid.Row="2">             <TextBlock Text="Subject - :" Foreground="Yellow" FontSize="14"         HorizontalAlignment="Center" VerticalAlignment="Center"/>             <TextBox x:Name="txtsubject" Width="315" Height="30"/>         </StackPanel>         <StackPanel Orientation="Vertical" Grid.Row="3">             <TextBox x:Name="txtmessage" Width="400" Height="120"         HorizontalAlignment="Left" VerticalAlignment="Top" />             <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">                 <Button x:Name="btnSend" Content="Send" Height="30" Width="100"          Click="btnSend_Click"/>                 <Button x:Name="btncancel" Content="Cancel" Height="30" Width="100" />             </StackPanel>         </StackPanel> </Grid>

Step 3

Now let's import a namespace to our code behind:

using System.Runtime.InteropServices.Automation;

Step 4

Now run your application and click on the 'Send' button. You will get an exception as shown below:

The operation is not supported in this context. You cannot call COM components directly from the browser due to security reasons. However you can achieve the same by making this Silverlight Application as an Out-Of-Browser application with Elevated Trust. You have to run this application in the Browser. To run this application in the browser, you must set this application to run Out-Of-Browser with Elevated Trust. Right click the Silverlight Application and go to Properties. Choose checkbox 'Enable running application Out of the browser' and click on 'Out of browser settings' button. From the setting window, chose a checkbox 'Require Elevated trust when running outside the browser'.

Step 5

Now you will have to follow the steps given below for enabling our Silverlight application to run within the browser, with Elevated trust.

1: Go to Start and click on Run.  Type 'RegEdit'. This will open the 'Registry Editor' window. Now the most important thing is that If you running the app on a 32 bit machine, you will have to find:

· HKEY_LOCAL_MACHINE\Software\Microsoft\Silverlight\

and if you are running on a 64-bit machine, you will have to find:

· HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Silverlight\

I took the reference of MSDN for this path. My computer is 64-bit, so I have chosen the second option. Once you find the above path in the registry, make a change to 'UpdateConsentMode' from '0' to '1' as shown below:

2: Now the second step is to Sign the .XAP file of our Silverlight application with code signing certificate. Right click t Sheilverlight application and go to properties. Choose ‘Signing from the left hand side’ and check the checkbox 'Sign the .XAP file' as shown below:

Now click on the button 'Create Test Certificate'. Enter the password and confirm password and click 'OK' button.

3: Now click on the 'More Details' button highlighted in blue colour. This will show you a 'Certificate' window. Click on the 'Install Certificate' button as shown below:

Clicking on the button brings up the 'Certificate Import wizard'. Click on the 'Next' button and choose 'Place all certificates in the following store'. Click on the Browse button. This will show you a 'Certificate Store'. Choose 'Trusted Publisher' and finish the wizard. Now repeat the same step to install this certificate in 'Trusted Root Certification Authorities'.

That's it! You are done with the configuration. Now hit 'F5' to launch the Silverlight application in a browser. Fill the details and click on the 'Send' button. This will show you a Internet Security dialog box. Click on the 'Allow' button and you will see the output as shown below: Silverlight 5 Hosting is European Windows Hosting Provider which focuses on Windows Platform only.

Silverlight 6 with Free ASP.NET Hosting - :: How to Use Silverlight Media Player to Play Video in ASP.NET

clock June 9, 2015 05:50 by author Rebecca

In this article, I am going to explain you about how to play (embed) WMV video file in ASP.NET using Silverlight Media Player. To use the SilverLight Media Player Control in ASP.NET, you will have to first download and install at least: Visual Studio 2008 Service Pack 1 and SilverLight 2.0 SDK.

Once all these have installed, you can start building your Media Player Application. You will have to drag the MediaPlayer component from the Toolbox as shown in figure below:

By default there are no skins available when you install the .SilverLight Tools you can get the skin files in the Program Files\Microsoft SDKs\Silverlight\v2.0\Libraries\Server\MediaPlayerSkin Folder. Just add the skins to your project using Add Existing Items in Visual Studio. Next, using the smart tag to choose the skin and add the Media File to be played:

You can also set other parameters like:

  • Volume - sets the volume of the Media Player Control
  • Auto-Play – determines whether the media file will be auto played or not when it is loaded.

Then, you can try to set the Media Source from code behind as shown below:


protected void Page_Load(object sender, EventArgs e)

    MediaPlayer1.MediaSource = "~/files/Butterfly.wmv";


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        MediaPlayer1.MediaSource = "~/files/Butterfly.wmv"
End Sub

Once all these settings have been done, you can run the application. The figure below displays the SilverLight Media Player:

Now, you're done!

Silverlight 6 with Free ASP.NET Hosting - :: How to Get User's Geo Location

clock June 3, 2015 06:19 by author Rebecca

In this tutorial, I'm going to tell you about getting the Geo-location of the user of your Silverlight Application. We will use Javascript as the core of our scenario.

Step 1

You will be calling following JavaScript API here in the aspx page:

 <script language="JavaScript" type="text/javascript" src=""></script>

Now there are functions in that API that will return the Latitude, Longitude, country name and whatever we demand. Some of the function are viz:

  •     geoip_country_code()
  •     geoip_country_name()
  •     geoip_latitude()
  •     geoip_longitude()

Instead of just calling these functions directly in Silverlight, we will write our functions that will call these functions and return whatever these functions return. For example here is the custom script written just beneath the API call:

<script type="text/javascript">

   function GetCountryCode() {

   return geoip_country_code();


  function GetCountryName() {

  return geoip_country_name();


  function GetLatitude() {

  return geoip_latitude();


   function GetLongitude() {

   return geoip_longitude();


So finally, here is what the aspx page with API call and the scripts that you have written:

 <script type="text/javascript" src="Silverlight.js"></script>

 <script language="JavaScript" type="text/javascript" src=""></script>

 <script type="text/javascript">

 function GetCountryCode() {

 return geoip_country_code();


 function GetCountryName() {

 return geoip_country_name();


 function GetLatitude() {

 return geoip_latitude();


 function GetLongitude() {

return geoip_longitude();


Step 2

Now let's move toward your mainpage. You must make the JavaScript function call from the main page. As you all know, it is a simple method call:


The XAML of the main page consists of four Text Blocks, each to pursue the respective value for Country code, Country Name, Latitude and Longitude.

 <Grid x:Name="LayoutRoot" Background="White">

 <TextBlock x:Name="txtCountryCode" Margin="20 20 0 0"/>

 <TextBlock x:Name="txtCountryName" Margin="20 40 0 0"/>

 <TextBlock x:Name="txtLatitude" Margin="20 60 0 0"/>

  <TextBlock x:Name="txtLongitude" Margin="20 80 0 0"/>


For giving the corresponding values to the Blocks, you need to write some C# in the code behind and in the constructor of the main page.

    public MainPage()



  txtCountryCode.Text = HtmlPage.Window.Invoke("GetCountryCode").ToString();

  txtCountryName.Text = HtmlPage.Window.Invoke("GetCountryName").ToString();

  txtLatitude.Text = HtmlPage.Window.Invoke("GetLatitude").ToString();

  txtLongitude.Text = HtmlPage.Window.Invoke("GetLongitude").ToString();  

That's it. Just hit F5 and run the project. It will provide you all the information you've requested in the code.

Happy coding!
