Solve Silverlight Arabic text issue in SharePoint 2010 Organization Browser and Media Web parts

Just came across the following solution to solve the common SharePoint 2010 Silverlight web parts (Org Browser and Media Web parts) Arabic display issue.

The solution is very simple:

  1. Locate the following 2 files [HierarchyChart.xap] and [MediaPlayer.xap] in [14 hive]\TEMPLATE\LAYOUTS\ClientBin
  2. Do the following for the 2 files:
    1. Very important to backup the 2 files first, just in case.
    2. The [.xap] file is basically a compressed folder (Archive), so open the file using a compression tool like [7-Zip]
    3. Open the [AppManifest.xaml] file using notepad, make sure that you open the file from the archive to make sure that the changes will be saved to the archive as well.
    4. Change the [RunTimeVersion] to [5.0.61118.0]
    5. Save the [AppManifest.xaml] (Inside the archive).
    6. Open your browser.
    7. Make sure that you clear the browser cache.
    8. Enjoy your organization browser in Arabic.


The idea beyond the solution is to force the Silverlight runtime to the newest version which has the proper RTL support.

Please, try this and submit your feedback.

I hope that helped


Silverlight Stock Rates Rotator


Silverlight is a rich framework that works in web browsers using a browser plug-in, just like Flash, but with it, you can interact more easily with .NET libraries. Silverlight has the same code-behind model that exists in ASP.NET, and operates under a modified light version from the .NET framework. With Silverlight, you can build Flash-like applications with full .NET server side code integration. Now, I’ll go through how to build a stock rates rotator with Silverlight and embed it into an ASPX page, step by step. First, you have to download the Silverlight Tools Beta 2 For Visual Studio 2008.

Using the code

Open Visual Studio 2008, and open a new project, select the Silverlight node under Visual C#, and select Silverlight Application:


Click OK to proceed to the following screen:


Select the first option to add a new web site to test your Silverlight controls, and click OK.


Notice these files in you solution:

  • App.xaml: The entry point for your application that tells which control to begin with, and within it, you can declare the shared variables.
  • Page.xaml: A Silverlight control which will hold the XAML and has a code-behind file “Page.xaml.cs” which holds the server side code.

Now, I’ll start developing the email form in “Page.xaml”:

<canvas xmlns:x=""
            <eventtrigger routedevent="Canvas.Loaded">
                    <storyboard repeatbehavior="Forever"
                           storyboard.targetproperty="(Canvas.Left)" x:name="animation">
                        <doubleanimation duration="0:0:10" to="-820"
                               from="0" storyboard.targetname="txtResult">
        <border opacity="1" background="Red">
            <textblock text=" Updating stock rates ...... please wait "
                       foreground="Wheat" x:name="txtLoading" />
        <textblock x:name="txtResult">

I made the animation to rotate the “txtResult” textblock from right to left forever. This is a very simple animation; also, I added another textblock to simulate the loading effect. Now, I’ll code the web service which will provide the stock rates to the Silverlight control.

public string GetStockData()
    // Just to see the loading effect

    StringBuilder stockData = new StringBuilder();
    Random randomRate = new Random();

    stockData.Append("USD " + randomRate.NextDouble() + "   |   ");
    stockData.Append("KD " + randomRate.NextDouble() + "   |   ");
    stockData.Append("GBP " + randomRate.NextDouble() + "   |   ");
    stockData.Append("EGP " + randomRate.NextDouble() + "   |   ");
    stockData.Append("AUD " + randomRate.NextDouble());

    return stockData.ToString();

It’s a very simple web method just to return the required string. Now, we must code calling the web service from the Silverlight control.

public partial class Page : UserControl
    # region "Public members"
    DispatcherTimer timer;
    BasicHttpBinding bind;
    EndpointAddress endPoint;
    // Change this to your local URL
    const string WebServiceUrl =
    WebServices.StockDataSoapClient stockService;
    # endregion

    public Page()

        // Initialize timer
        timer = new DispatcherTimer();
        timer.Interval = new TimeSpan(0, 0, 10);
        timer.Tick += new EventHandler(timer_Tick);
        // Initialize the web service proxy and add the event handler
        bind = new BasicHttpBinding();
        endPoint = new EndpointAddress(WebServiceUrl);
        stockService = new WebServices.StockDataSoapClient(bind, endPoint);
        stockService.GetStockDataCompleted += new
        // Start the timer
    // Invoked when the calling completed or timed out
    void stockService_GetStockDataCompleted(object sender,
         StockRotator.WebServices.GetStockDataCompletedEventArgs e)
            // Update the result
            txtResult.Visibility = Visibility.Visible;
            txtResult.Text = e.Result.ToString();
        catch (Exception ex)
            // Display the error
            txtResult.Text = ex.InnerException.Message;
            // Hide the loading textbloxk and restart the timer
            txtLoading.Visibility = Visibility.Collapsed;

    void timer_Tick(object sender, EventArgs e)
        txtLoading.Visibility = Visibility.Visible;
        txtResult.Visibility = Visibility.Collapsed;
        // Make the async call to the web service

And this is the test page in action:


And, this with the data displayed:
