以编程方式添加样式触发器 [英] Programmatically add style trigger

问题描述

任何人都可以帮助您以编程方式添加以下样式：

Can anyone please help how to programatically add the following style:

<style>
 <style.Triggers>
     <Trigger Binding="{Binding CustomerId}" Value ="1"/>
     <setter Property="Background" Value="Red"/>
 </style.Triggers>
</style>

推荐答案

您的XAML不正确，但是我想您想要看到这个：

Your XAML is incorrect, but I guess you want to see this:

Style st = new Style();

DataTrigger tg = new DataTrigger()
{
    Binding = new Binding("CustomerId"),
    Value = 1
};

tg.Setters.Add(new Setter()
{
    Property = Control.BackgroundProperty,
    Value = ColorConverter.ConvertFromString("Red")
});

st.Triggers.Add(tg);
