    Hello,
    when trying to set the LayoutMode dependency property of a RadRichTextBox using a style, the application crashes.

    Test case:
    1. Create a new Silverlight application.
    2. Replace MainPage.xaml with:
    <UserControl
      x:Class="SilverlightApplication2.MainPage"
      mc:Ignorable="d"
      d:DesignHeight="300" d:DesignWidth="400">
     
      <Grid x:Name="LayoutRoot" Background="White" Margin="5">
     
        <Grid.Resources>
          <Style TargetType="tk:RadRichTextBox">
            <Setter Property="LayoutMode" Value="Flow" />
          </Style>
        </Grid.Resources>
     
        <tk:RadRichTextBox />
         
      </Grid>
    </UserControl>

    3. Run

    If you comment the style definition, the application runs correctly.

    Hello Patrick,

    Thank you for your question.

    LayoutMode is a nullable property (of type DocumentLayoutMode?) and for some reason it cannot be set through a style using the "normal" syntax, even though it usually shows in the designer.

    However, you can set it like this:

    <Style TargetType="telerik:RadRichTextBox">
        <Setter Property="LayoutMode">
            <Setter.Value>
                <telerik:DocumentLayoutMode>Flow</telerik:DocumentLayoutMode>
            </Setter.Value>
        </Setter>
        <Setter Property="IsSpellCheckingEnabled" Value="False"/>
    </Style>

    We didn't observe any issues with the property IsSpellCheckingEnabled. I hope this helps!

    All the best,
