在运行时将数据绑定到WPF列表框
我是WPF的新手，我试图在运行时启动ListBox值，我只需要以500的间隔（即0,500,1000等等）添加0-15000的值。 至于现在我正在使用 -
一旦类初始化，我就可以简单地将值添加到列表中 -
List<int> intTimeData = new List<int>();
for (int i = 0; i <= 15000; )
{
intTimeData.Add(i);
i += 500;
}
listBoxIntTime.ItemsSource = intTimeData;
问题是它不起作用列表看起来是smooshi：
......有什么帮助吗？
xaml代码是 -

使用XAML进行开发时应使用ObservableCollection＆lt;＆gt;而不是List＆lt;＆gt; http://msdn.microsoft.com/en-us/library/ms668604.aspx。 为什么？因为每次修改集合时，Observable集合都会通知更改以刷新视图。 它应该是这样的：
ObservableCollection<int> collection = new ObservableCollection<int>(); ListBox.DataSource = collection;
for (int i = 0; i <= 15000; )
{
collection.Add(i);
i += 500;
}
现在，每次调用add方法时，都将使用数据

更新您的DataTemplate，让控件显示您的值，就像我在
下面使用TextBlock一样 <DataTemplate>
<TextBlock Text="{Binding}"/>
</DataTemplate>
答案 2 :(得分：0)
如果您有视图模型，则可以使用绑定将数据附加到视图，如下所示：
ViewModel.cs
public class ViewModel
{
public List<int> Items { get; set; }
public ViewModel( )
{
Items = new List<int>( );
for( int index = 0; index < 15000; index += 500 )
{
Items.Add( index );
}
}
}
View.xaml.cs
public partial class View : Window
{
public View( )
{
this.DataContext = new ViewModel( );
}
}
View.xaml
<ListBox ItemsSource="{Binding Items}" />
