[Solved] Blank Text

[Jeremy Cook]

I have a richTextBox using a htmlDataProvider, however when it starts up the text is blank.

I am able to select the text in the RichTextBox but the text is still blank. I am also able to write in the RichTextBox and the text is still blank.
Here is the code, it's prett simple.

Xaml

<UserControl x:Class="RadControlsSilverlightApp1.MainPage"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:docs="clr-namespace:Telerik.Windows.Documents.FormatProviders.Html;assembly=Telerik.Windows.Documents.FormatProviders.Html"
             mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480"
             Background="Black">
    <UserControl.Resources>
        <docs:HtmlDataProvider x:Key="html"
                               RichTextBox="{Binding ElementName=rtb}"
                               Html="{Binding html, Mode=TwoWay}">
        </docs:HtmlDataProvider>
    </UserControl.Resources>
  <Grid x:Name="LayoutRoot">
        <StackPanel>
            <telerik:RadRichTextBox x:Name="rtb" BorderBrush="Black" BorderThickness="1" IsSpellCheckingEnabled="False" />
            <TextBox Text="{Binding html,Mode=TwoWay}"/>
        </StackPanel>
  </Grid>
</UserControl>

Code Behind

public partial class MainPage : UserControl
   {
       public MainPage()
       {
           InitializeComponent();
      this.DataContext = this;
           this.Loaded += new RoutedEventHandler(MainPage_Loaded);
       }
       void MainPage_Loaded(object sender, RoutedEventArgs e)
       {
            this.html = "Some Text";
      }
       public string html
       {
           get { return (string)GetValue(htmlProperty); }
           set { SetValue(htmlProperty, value); }
       }
       // Using a DependencyProperty as the backing store for html.  This enables animation, styling, binding, etc...
       public static readonly DependencyProperty htmlProperty =
           DependencyProperty.Register("html", typeof(string), typeof(MainPage),null);
   }

I am using version 2010.3.1018.1040

thanks

Hi Jeremy Cook,

This was a bug in the Q3.Beta (2010.3.1018), which we fixed immediately.
If you upgrade to the official Q3 release (2010.3 1110), the Service Pack (2010.3 1314) or the latest internal build (2010.3 1331), the problem will be resolved.

Greetings,
Iva
