與LINQ查詢

Question

我有一個組合框名爲「CurrencyOne」填充組合框，我寫了LINQ查詢

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

，並在XAML費爾

<ComboBox Name="CurrencyOne"/> 

我怎樣才能確保組合框將填充查詢結果？

Answer 1

您需要設置ItemsSource列出應顯示所以無論是直接設置它沒有DataContext：

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

或綁定ItemsSource當前DataContext：

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

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

Answer 2

您正在尋找ItemsSource而不是DataContext：

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