C# 在运行应用程序之前，不会从属性信息更改设计视图

当我直接从属性信息更改为依赖属性时，在运行应用程序之前，我的设计视图中不会立即显示结果

   <local:OnOffToggleButton HorizontalAlignment="Left" Margin="35,34,0,0" x:Name="onOffToggleButton1" VerticalAlignment="Top" StateOf4="3" GotFocus="onOffToggleButton1_GotFocus" Loaded="onOffToggleButton1_Loaded" />


public class OnOffToggleButton : Control// ToggleButton
{

    public static readonly DependencyProperty StateOf4Property;

    static OnOffToggleButton()
    {

        OnOffToggleButton.StateOf4Property = DependencyProperty.Register("StateOf4", typeof(int), typeof(OnOffToggleButton));
    }

    public int StateOf4
    {
        get
        {
            return (int)this.GetValue(OnOffToggleButton.StateOf4Property);
        }
        set
        {
            SetValue(OnOffToggleButton.StateOf4Property, value);
        }          
    }
}

公共类OnOffToggleButton:Control//ToggleButton
{
4属性的公共静态只读从属属性状态；
静态OnOffToggleButton（）
{
OnOffToggleButton.StateOf4Property=DependencyProperty.Register（“StateOf4”、typeof（int）、typeof（OnOffToggleButton））；
}
公共int状态4
{
得到
{
返回（int）this.GetValue（OnOffToggleButton.StateOf4Property）；
}
设置
{
设置值（OnOffToggleButton.Stateof4属性，值）；
}          
}
}

}

这里是我的切换按钮的默认值、模板和样式

你能帮帮我吗！：）

我认为触发器在VS designer中不起作用

解决方法是使用VisualStateManager并将StateOf4值转换为不同的视觉状态。这也适用于designer。

这是大量代码；你能提供相关的代码并更具体一些吗？
