ScheduleView row height

[Sergey]

I want to reduce the height of the ScheduleView row. I tried to set the height of the VerticalBottomLevelStyle and AppointmentItemStyle to fixed value (10) and while the appointment height did become 10 the row height doesn't shrink below 23:

<UserControl.Resources>

        <tvSchedule:ViewModel x:Key="ViewModel" />

 

        <common:ResourceAppointmentItemStyleSelector x:Key="AppointmentItemStyleSelector">

            <common:ResourceAppointmentItemStyleSelector.NewsHorizontalStyle>

                <Style TargetType="scheduleView:AppointmentItem" BasedOn="{StaticResource AppointmentItemBaseStyle}"/>

            </common:ResourceAppointmentItemStyleSelector.NewsHorizontalStyle>

        </common:ResourceAppointmentItemStyleSelector>

 

        <Style x:Key="AppointmentItemBaseStyle" TargetType="scheduleView:AppointmentItem">

            <Setter Property="Height" Value="10" />

        </Style>

 

        <Style x:Key="VerticalBottomLevelGroupHeaderStyle" TargetType="telerik:GroupHeader">

            <Setter Property="Height" Value="10" />

        </Style>

    </UserControl.Resources>

 

    <Grid DataContext="{StaticResource ViewModel}">

        <telerik:RadScheduleView AppointmentStyleSelector="{StaticResource AppointmentItemStyleSelector}">

            <telerik:RadScheduleView.GroupHeaderStyleSelector>
                <telerik:OrientedGroupHeaderStyleSelector
     VerticalBottomLevelStyle="{StaticResource VerticalBottomLevelGroupHeaderStyle}" />  

            </telerik:RadScheduleView.GroupHeaderStyleSelector>

 

            <telerik:RadScheduleView.GroupDescriptionsSource>

                <scheduleView:GroupDescriptionCollection>

                    <scheduleView:DateGroupDescription />

                </scheduleView:GroupDescriptionCollection>

            </telerik:RadScheduleView.GroupDescriptionsSource>

 

            <telerik:RadScheduleView.AppointmentsSource>

                <telerik:ObservableAppointmentCollection>

                    <telerik:Appointment Subject="WORLD NEWS" Start="04/28/2013 6:00" End="04/28/2013 10:00">

                        <telerik:Appointment.Resources>

                            <scheduleView:Resource ResourceName="News" ResourceType="Programme" />

                        </telerik:Appointment.Resources>

                    </telerik:Appointment>

                </telerik:ObservableAppointmentCollection>

            </telerik:RadScheduleView.AppointmentsSource>

 

            <telerik:RadScheduleView.ViewDefinitions>

                <telerik:WeekViewDefinition Orientation="Horizontal"/>

            </telerik:RadScheduleView.ViewDefinitions>

 

        </telerik:RadScheduleView>

    </Grid>

How can I reduce the row height to 10?
