如何在CustomControl中以编程方式应用Style

Question

我在WPF中有一个自定义按钮，ColorPickerButton，并为它应用了样式“ColorPickerButtonStyle”，我必须像这样在xmal中应用;

<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" />

这个工作正常。但是如果我忘记应用样式“{DynamicResource ColorPickerButtonStyle}”那么按钮看起来就像死鱼。 我在这里要做的是，我想应用这部分＆lt; ResourceDictionary Source =“RDColorPicker.xaml”/＆gt;和Style =“{DynamicResource ColorPickerButtonStyle}”将嵌入ColorPickerButton类的实现部分，就像在Class的构造函数中一样;

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

类似的东西：

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