使用Linq查询填充组合框

Question

我有一个名为“CurrencyOne”的组合框，我写了一个Linq查询

 var curren = (from cur in data.MyCurrencys select cur.Value).ToList();
 CurrencyOne.DataContext = curren;

和xaml fils

<ComboBox Name="CurrencyOne"/>

如何确保组合框将填充查询结果？

Answer 1

您正在寻找ItemsSource而不是DataContext：

var curren = (from cur in data.MyCurrencys select cur.Value).ToList();
CurrencyOne.ItemsSource = curren;

Answer 2

您需要将ItemsSource设置为应显示的列表，以便在没有DataContext的情况下直接设置：

var curren = (from cur in data.MyCurrencys select cur.Value).ToList();
CurrencyOne.ItemsSource = curren;

或将ItemsSource绑定到当前DataContext：

var curren = (from cur in data.MyCurrencys select cur.Value).ToList();
CurrencyOne.DataContext = curren;

<ComboBox Name="CurrencyOne" ItemsSource="{Binding}"/>
