UWP将GetBindingExpression与x:Bind结合使用 [英] UWP Using GetBindingExpression with x:Bind

问题描述

我将我的UWP应用程序从Binding重写为x:Bind.我在不同的文本框中有一个TextChanged事件.通过绑定，我可以使用GetBindingExpression来更新模型.x:Bind有等效的Methode吗?或者我怎么用x:Bind做到?

I am rewrite my UWP Application from Binding to x:Bind. I have a TextChanged Event on different Textboxes. With Binding I could use GetBindingExpression to update the Model. Is there an equivalent Methode for x:Bind? Or how could I make it with x:Bind?

    public void TextBox_TextChanged(object sender, TextChangedEventArgs e)
    {
        var binding = ((TextBox)sender).GetBindingExpression(TextBox.TextProperty);
        binding.UpdateSource();
    }

推荐答案

我曾经尝试过这样做，但没有成功.我认为暂时不可用，因为绑定只是标记扩展.这是文档和使用示例 https://msdn.microsoft.com/en-us/library/windows/apps/mt204783.aspx

I've tried to do this before without success. I think is not available for now, because Bind it's just a markup extension. Here is the documentation and examples how to use it https://msdn.microsoft.com/en-us/library/windows/apps/mt204783.aspx
