Question

任何人都可以請幫助如何編程添加以下樣式：

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

你的XAML是不正確的，但我猜你想看到這一點：

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);
