WPF：获取属性，一个控制在code绑定到背后 [英] WPF: Get Property that a control is Bound to in code behind

问题描述

我试图找到一种方式来获得的属性。它控件绑定（在C＃）。

I am trying to find a way to get the Property to which a control is bound (in c#).

如果我有以下几点：

<dxe:ComboBoxEdit DisplayMember="Name" ItemsSource="{Binding Path=NameOptions, Mode=OneTime}" SelectedItem="{Binding Path=Name, UpdateSourceTrigger=PropertyChanged}" />

我现在试图去其中的SelectedItem绑定到，即结果应该是名的位置。然后在code，我需要做一些东西与视图模型属性。问题是，我不能只是很难code这个，因为它是一个需要与表单上的每个控件工作的一个通用的方法。

I am now trying to get the location to which the SelectedItem is bound to, i.e. the result should be "Name". Then in code I need to do some stuff with that ViewModel Property. Issue is that I can't just hard code this as it is a generic method that needs to work with each control on the form.

谢谢，

推荐答案

我觉得这个应该这样做：

I think this should do it:

BindingExpression be = BindingOperations.GetBindingExpression((FrameworkElement)yourComboBox, ((DependencyProperty)Button.SelectedItemProperty));
string Name = be.ParentBinding.Path.Path;
