Hello Alexander,

You could achieve the wanted result by creating an implicit Style targeting the TextMessageControl element. The DataContext of the element is TextMessage. This object has Author property, which could be used to set the Background property, via a DataTrigger trigger:

<Style TargetType="chat:TextMessageControl">
    <Style.Triggers>
        <DataTrigger Binding="{Binding Author.Name}" Value="DefaultAuthor">
            <Setter Property="Background" Value="red"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

In order to target the TextMessageControl type, you would need to add the following namespace:

<Window xmlns:chat="clr-namespace:Telerik.Windows.Controls.ConversationalUI;assembly=Telerik.Windows.Controls.ConversationalUI" />

With this said, I hope the provided information works in your current project scenario.
