      We are making use of telerik silverlight chart and want to show the label for marked zone as in the radChart here
    There is no property with the name Label for marked zone.
     Is there anyway that we can achieve this?

    Hello Donlad,

     This is not a supported feature, however, it is easy to achieve this by retemplating the MarkedZone.
    In XAML you will need to retemplate MarkedZone class:

    <Style x:Key="NewMarkedZones" TargetType="telerik:MarkedZone">
        <Setter Property="Background" Value="#66666666" />
        <Setter Property="Template" >
                <ControlTemplate TargetType="telerik:MarkedZone">
                        <Rectangle Grid.ColumnSpan="3"
                            Fill="{TemplateBinding Background}"
                           Stroke="{TemplateBinding Stroke}"
                           StrokeThickness="{TemplateBinding StrokeThickness}"
                           Margin="{TemplateBinding ElementMargin}"
                           Style="{TemplateBinding ElementStyle}" />
                        <TextBlock  Text="{Binding}" Margin="{TemplateBinding ElementMargin}"/>
    I have marked the new part of the MarkedZone style in orange.
    I added a grid layout wrapper and put a TextBlock together with the rectangle that actually displays the marked zone.

    In code behind you need to add MarkedZone's new style together with a string for a DataContext. This string is bound to Text  property of TextBlock:

               new MarkedZone(25, 50, 50000, 65000)
                   Style = this.LayoutRoot.Resources["NewMarkedZones"] as Style,
                   DataContext = "Label text"

    I hope this will help you out.

    Kind regards,
