如何在CustomControl中以編程方式應用Style

Question

我有一個自定義按鈕，ColorPickerButton，在WPF和樣式“ColorPickerButtonStyle”應用它，我必須在這樣的xmal中應用;

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="RD_ColorThemes.xaml"/>
           <ResourceDictionary Source="RDColorPicker.xaml"/>
        </ResourceDictionary.MergedDictionaries> 
    </ResourceDictionary>
</UserControl.Resources>

<Grid x:Name="grd">
<cp:ColorPickerButton x:Name="btn" Width="25" Height="25" 
Style="{DynamicResource ColorPickerButtonStyle}" 
Click="ColorPickerButton_Click" />

這工作正常。 但是如果我忘記應用樣式“{DynamicResource ColorPickerButtonStyle}”那么按鈕看起來就像死魚。 我在這里要做的是，我想將這部分<ResourceDictionary Source =“RDColorPicker.xaml”/>和Style =“{DynamicResource ColorPickerButtonStyle}”應用於ColorPickerButton類的實現部分，就像在構造函數中一樣階級;

public class ColorPickerButton:Button
{
   ....
   public ColorPickerButton()
   {
      ....
      //How to call resourcedictionary and apply style "ColorPickerButtonStyle" for this      button 
   }
}

就像是：

this.SetResourceReference(ColorPickerButton.StyleProperty, "ColorPickerButtonStyle");
