為什么我的串列視圖是空的，而“Klanten”有物件？
我也洗掉了物件類中的 toString。
c#建構式
public partial class Klantbeheerder: Window {
public ObservableCollection < Klant > Klanten;
private KlantManager _manager;
public Klantbeheerder() {
InitializeComponent();
_manager = new(new KlantRepo(ConfigurationManager.ConnectionStrings["connStr"].ToString()));
Klanten = _manager.GeefKlanten();
DataContext = Klanten;
}
窗戶
d:DataContext="{d:DesignInstance local:Klantbeheerder, IsDesignTimeCreatable=True}"
內部網格
<ListView
x:Name="lstvKlanten"
Height="270"
Margin="0,15,15,15"
HorizontalAlignment="Left"
ItemsSource="{Binding Klanten}"
SelectionMode="Single">
<ListView.View>
<GridView>
<GridViewColumn
Width="50"
DisplayMemberBinding="{Binding Id}"
Header="Id" />
<GridViewColumn
Width="150"
DisplayMemberBinding="{Binding Naam}"
Header="Naam" />
<GridViewColumn
Width="100"
DisplayMemberBinding="{Binding Adres}"
Header="Adres" />
</GridView>
</ListView.View>
</ListView>
uj5u.com熱心網友回復：
為什么使用ListView翻譯網格？使用DataGrid，很簡單：
MainWindow.xaml：
<DataGrid ItemsSource="{Binding Products}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Product" Binding="{Binding Name}" />
<DataGridTextColumn Header="Price" Binding="{Binding Price}" />
</DataGrid.Columns>
</DataGrid>
MainWindow.xaml.cs：
//LOOK, THIS IS PROPERTY!!
public ObservableCollection<Product> Products { get; set; }
public MainWindow()
{
InitializeComponent();
Products = new ObservableCollection<Product>();
Products.Add(new Product { Name = "Apple", Price = 1 });
Products.Add(new Product { Name = "Banana", Price = 2 });
DataContext = this;
}
