WPF RadGridView containing RadDatePicker - How to change Style of date picker upon Trigger of GridViewRow IsSelected

[Joe]

Specifically i want to change the background color of the RadDatePicker (as well as the whole row) when i am changing the currently selected row with the up/down arrow keys.

To change the color of current row (highlighted) is achieved somewhat using Style.Triggers as per the following code:

<telerik:RadGridView Name="tlrkGridView"
                     IsFilteringAllowed="False" ShowGroupPanel="False" CanUserSortColumns="False" IsSynchronizedWithCurrentItem="True"
                     ItemsSource="{Binding Players}"
                     AutoGenerateColumns="False">
    <telerik:RadGridView.RowStyle>
        <Style TargetType="{x:Type telerik:GridViewRow}">
            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Background" Value="AliceBlue"></Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </telerik:RadGridView.RowStyle>
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding StartDate}" DataFormatString="{} {0: d/MM/yyyy}" Header="Custom Header">
            <telerik:GridViewDataColumn.CellTemplate>
                <DataTemplate>
                    <telerik:RadDatePicker x:Name="datePicker" DateTimeWatermarkContent="<Select a date>" SelectedValue="{Binding StartDate, Mode=OneWay}" />
                </DataTemplate>
            </telerik:GridViewDataColumn.CellTemplate>
            <telerik:GridViewDataColumn.CellEditTemplate>
                <DataTemplate>
                    <telerik:RadDatePicker x:Name="datePickerEdit" DateTimeWatermarkContent="<Select a date>" SelectedValue="{Binding StartDate, Mode=TwoWay}" />
                </DataTemplate>
            </telerik:GridViewDataColumn.CellEditTemplate>
        </telerik:GridViewDataColumn>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding EndDate}" DataFormatString="{} {0: d/MM/yyyy}"  />
        <telerik:GridViewComboBoxColumn DataMemberBinding="{Binding ClubID}"
                                        ItemsSource="{Binding Clubs, Source={StaticResource MyViewModel}}"
                                        SelectedValueMemberPath="ID" >
            <telerik:GridViewComboBoxColumn.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition />
                            <ColumnDefinition />
                            <ColumnDefinition Width="*"></ColumnDefinition>
                        </Grid.ColumnDefinitions>
                        <TextBlock Text="{Binding ID}"/>
                        <TextBlock Text=" - " Grid.Column="1"/>
                        <TextBlock Text="{Binding Name}"  Grid.Column="2"/>
                    </Grid>
                </DataTemplate>
            </telerik:GridViewComboBoxColumn.ItemTemplate>
        </telerik:GridViewComboBoxColumn>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

But HOW TO MAKE THE TRIGGER AFFECT/SET THE STYLE OF THE RadDatePicker which is contained within the RadGridView? Is it do-able in XAML ?

Basically i want to make the color of a selected row (the whole row) the same, regardless of whether it contains default column types, or other controls within a column. The GridViewComboBoxColumn behaves as expected, and EndDate field in my example behaves as expected. The reason i am using a RadDatePicker is because i want to show the Calendar icon in cell view mode.
