简单的WPF MVVM +绑定 [英] Simple WPF + MVVM binding

问题描述

我有一个名为类 mywindow的从窗口中提炼出来。我使用MVVM模式，这样，代码隐藏我有以下字段：

I have a class named MyWindow the derives from Window. I use the MVVM pattern so in code-behind I have the following field:

public MyViewModel ViewModel = new MyViewModel();

视图模型包含<$ C的集合$ C>人，以及所有我想要做的是绑定一个组合框来此集合，展示人员。名称为每个人。

标头，我也想在<$ C $另一场C>视图模型，将数据绑定到选定的项目。

ViewModel contains a collection of Person, and all I'd like to do is to bind a ComboBox to this collection, show Person.Name as the header for each Person.
I would also like to have another field in ViewModel that will be data-bound to the selected item.

请帮我。

推荐答案

那么首先你必须设置你的窗口，在构造函数中viewmdodel的DataContext的，如果你还没有这样做的：

Well firstly you have to set the datacontext of your window to the viewmdodel in the constructor if you have not already done so:

this.DataContext = MyModelView;

然后就可以设置组合框，如下所示：

Then you can set the ComboBox as follows:

<ComboBox ItemsSource={Binding Persons} SelectedItem={Binding CurrentPerson,Mode=TwoWay} DisplayMemberPath="Name"/>

在哪里的人是人的收集和当前人是物业所选择的人将被绑定到。

Where Persons is the Collection of Persons and Current Person is the Property the selected person will be bound to.
