WPF组合框与List< string>的绑定 [英] WPF Combobox binding with List<string>

问题描述

我有两个属性，一个是字符串列表，另一个是字符串.

I have two properties, one which is a list of string and the other just a string.

private List<String> _property;
public List<String> Property
get
{
return new List<string>(){"string1", "string2"};
}
set{_property = value
}

public String SimpleStringProperty{get;set;}

我也在XAML中定义了一个组合框

I also have a Combobox defined in XAML as such

<Combobox ItemsSource="{Binding Property , Mode="TwoWay"}" Text="Select Option" />    

现在，组合框正确显示了两个选项:"string1"和"string2"

Now the combobox correctly displays two options :"string1" and "string2"

当用户选择一个或另一个时，我想用该值设置 SimpleStringProperty .但是，通过双向绑定从组合框返回的值"不是selectedItem，而是 List< String> .我该怎么做呢?我是wpf的新手，所以请原谅我的业余爱好.

When the user selects one or the other, I want to set SimpleStringProperty with that value. However, the 'value' im getting back from the combobox through the two way binding is not the selectedItem, but the List<String>. How can I do this right? I'm fairly new to wpf, so please excuse the amateurism.

推荐答案

<Combobox ItemsSource="{Binding Property}" SelectedItem="{Binding SimpleStringProperty, Mode=TwoWay}" Text="Select Option" />

这未经测试，但至少应该与您所需要的非常接近.

That's untested, but it should at least be pretty close to what you need.
