UpdateSourceTrigger属性在Silverlight中更改了吗? [英] UpdateSourceTrigger PropertyChanged in Silverlight?
问题描述
我敢肯定，当您键入一个文本框时，您中的大多数人都会遇到这种情况，您想立即根据输入的内容过滤ViewCollection.
I am sure most of you have come across this when you type in a textbox you like instantly to filter a ViewCollection according to has been typed.
在WPF中非常简单，只需将文本绑定的UpdateSourceTrigger更改为PropertyChanged.
Its very straight forward in WPF, just change the UpdateSourceTrigger for Text binding to PropertyChanged.
如您所料，Silverlight没有它.只是默认的和显式的.
As you would expect Silverlight doesnt have it. There is just a default and explicit instead.
我想到了将交互行为绑定到文本框的TextChanged事件的想法.您会推荐这种方法还是有更好的方法?
I had the idea to bind an Interaction behavior to TextChanged event of the textbox instead. Would you recommend this approach or is there a better way?
推荐答案
行为是解决问题的一种方法，我认为这是公认的方法.我还看到了用附加属性解决它的文章(可能是更干净的XAML语法，但我从未尝试过).这些是第一个出现的链接，我完全没有对其进行测试(应该很容易找到其他链接):
A behavior is the way it was solved on my team, and I think is the generally accepted method. I have also seen articles solving it with Attached Properties (might be cleaner XAML syntax, but I have never tried it). These are the first links that came up, completely untested by me (should be easy enough to find others):
