wpf prism<ItemsControl ItemsSource 详解代码示例

以下是一个使用WPF Prism框架中的ItemsControl控件和绑定数据源的示例代码：

1. 在XAML中添加ItemsControl控件

<ItemsControl x:Name="MyItemsControl" ItemsSource="{Binding MyItems}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <!-- 在这里定义控件模板 -->
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

2. 在ViewModel中定义数据源和属性

private ObservableCollection<MyItemViewModel> _myItems;
public ObservableCollection<MyItemViewModel> MyItems
{
    get { return _myItems; }
    set { SetProperty(ref _myItems, value); }
}

3. 在ViewModel的构造函数中初始化数据源

MyItems = new ObservableCollection<MyItemViewModel>();
MyItems.Add(new MyItemViewModel() { Title = "Item 1", Description = "Description for Item 1" });
MyItems.Add(new MyItemViewModel() { Title = "Item 2", Description = "Description for Item 2" });
MyItems.Add(new MyItemViewModel() { Title = "Item 3", Description = "Description for Item 3" });

4. 在MyItemViewModel中定义需要绑定的属性

public class MyItemViewModel : BindableBase
{
    private string _title;
    public string Title
    {
        get { return _title; }
        set { SetProperty(ref _title, value); }
    }

    private string _description;
    public string Description
    {
        get { return _description; }
        set { SetProperty(ref _description, value); }
    }
}

5. 在DataTemplate中定义控件模板，绑定对应的属性

<DataTemplate>
    <StackPanel>
        <TextBlock Text="{Binding Title}" />
        <TextBlock Text="{Binding Description}" />
    </StackPanel>
</DataTemplate>

这样，就可以在界面中展示绑定的数据源了。
