    I have a LightSwitch 2012 project in which I added a Silverlight project to include the Telerik RadRichTextBox as a custom control to display text that is stored as RTF data in the database.
    My control has the following xaml:

        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="Kbc.Msi.UserControls.InterfaceTechnicalDescriptionViewer"
        d:DesignHeight="600" d:DesignWidth="800">
        <Grid x:Name="LayoutRoot" Background="White">
                <RowDefinition Height="*"/>
                <ColumnDefinition Width="*"/>
            <telerik:RadRichTextBox x:Name="radRichTextBox"
                                    Grid.Row="0" Grid.Column="0"
                    <rtfProvider:RtfDataProvider x:Key="provider" x:Name="Provider"
                                                 RichTextBox="{Binding ElementName=radRichTextBox}"
                                                 Rtf="{Binding Path=Content, Mode=TwoWay}" />


    The control is added on a LightSwitch details screen and bound to a text property that contains text stored as rtf.
    For some reason however the control is showing perfectly on the screen, but no data is shown in the control.
    I know data is present, because for debugging purposes I've added a text control to show the data as plain text.
    Is there something I'm missing here?

    Might be that we found the issue.
    It looks like the rtf text (imported automatically through an SSIS package) has a space in front of the rtf formatted text, which is causing the issue. I'll verify once I get a new import file without the extra space to see if this was the issue...

    Hi Jean Marie,
    You can also use RtfDataProvider.ImportException event for troubleshooting the exceptions during the import process.
    If the problem can be reproduced with valid RTF document, we would like to send it to us for further investigation.

    Thanks for the tip, will make sure to try that out, but I'm pretty sure that the root cause of the issue is an invalid file format.
    Once we get to try with a valid document I will update this post.
