Easily change the CloseButtonContainer Background

[H.-G.]

Is there a way to change the CloseButtonContainer.Background or the Background of the PART_Close ToggleButton without overwriting the whole template? We are using the Transparent Theme. I already changed the CalendarStyle and the ClockStyle to a usable Background color. But the Close-Button at the bottom is hardly visible. I don't want to put over 1500 extra lines of Template-Code to my Project. Unfortunately the PART_DropDownButton, CloseButtonContainer and the PART_Close Button itself are not accesible from a simple Style. I tried to set a Ressource to the DateTimePicker overwriting all RadToggleButtonStyles, but as seen in the Template the Part_Close Button uses its own Style and Template.

  <Style TargetType="telerik:RadCalendar" x:Key="CalendarBackStyle">
    <Setter Property="Background" Value="{StaticResource NormalToLightBackgroundBrush}" />
  </Style>

  <Style TargetType="telerik:RadClock" x:Key="ClockBackStyle">
    <Setter Property="Background" Value="{StaticResource NormalToLightBackgroundBrush}" />
  </Style>

  <Style TargetType="telerik:RadDateTimePicker">
    <Setter Property="CalendarStyle" Value="{StaticResource CalendarBackStyle}" />
    <Setter Property="ClockStyle" Value="{StaticResource ClockBackStyle}" />
  </Style>

<!--Overwrite Resources, didn't work-->
<telerik:RadDateTimePicker>
      <telerik:RadDateTimePicker.Resources>
           <Style TargetType="telerik:RadDropDownButton">
             <Setter Property="Background" Value="Lime" />
            </Style>
       </telerik:RadDateTimePicker.Resources>
</telerik:RadDateTimePicker>

<!--This works but doesn't help because all borders are styled-->
<telerik:RadDateTimePicker>
      <telerik:RadDateTimePicker.Resources>
           <Style TargetType="Border">
             <Setter Property="Background" Value="Lime" />
            </Style>
       </telerik:RadDateTimePicker.Resources>
</telerik:RadDateTimePicker>

Is there a simple solution?

Hi,

At the moment we do not have a separate style for CloseButtonContainer. The only way to modify it is to edit inside the template of RadDateTimePicker.
