Style for DatePicker

[Dan M]

I am trying to apply a Theme to the DatePicker control but I also want to hide the week numbers in the calendar pop-up. This is the code

<Window x:Class="WPF_RadDateTimePicker.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:WPF_RadDateTimePicker"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style x:Key="calendarStyle" TargetType="telerik:RadCalendar">           
            <Setter Property="AreWeekNumbersVisible" Value="False" />
        </Style>
    </Window.Resources>
 
    <StackPanel>        
        <telerik:RadDateTimePicker Width="100" VerticalAlignment="Center"
                                   CalendarStyle="{StaticResource calendarStyle}"
                                   telerik:StyleManager.Theme="Expression_Dark"/>
    </StackPanel>
</Window>

As soon as I reffer to the static calendarStyle the Expression_Dark theme is no longer correctly applied to the Calendar control 
otherwise works fine. How can I fix this?? ( I using 2010 Q3 version of the product)

Hello Dan,

You will need to base your CalendarStyle on the Expression theme to prevent the style from overriding the theme. Use the ThemeResourceKey as follows:

<Style x:Key="CalendarStyle" TargetType="telerik:RadCalendar" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Expression_DarkTheme, ElementType=telerik:RadCalendar}}">
          <Setter Property="AreWeekNumbersVisible" Value="False" />
</Style>
