c# - 使用 MVVM 将数据绑定(bind)到 WPF 中的 ListView 控件

Question

我已尝试将数据绑定(bind)到 ListView 控件中:

<ListView Margin="8" Height="400" Width="650" 
    ItemsSource="{Binding Path=MyData}">
    <ListView.View>
         <GridView>
             <GridViewColumn Header="ID" Width="Auto" 
                  DisplayMemberBinding="Binding Path=ID}" >
             </GridViewColumn>
             <GridViewColumn DisplayMemberBinding="{Binding Path=Name}" 
                  Header="Name" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Path=Price}" 
                  Header="Price" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Path=Author}" 
                  Header="Author" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Path=Catalog}" 
                  Header="Catalog" Width="100"/>
           </GridView>
    </ListView.View>
</ListView>

  ObservableCollection<TableInfo> _MyData
  public ObservableCollection<TableInfo> MyData{ get; set; }

但是，它不会在窗口中显示任何内容，但 MyData 是一个 ObservableCollection。如何绑定(bind)数据？

谭雅，

如果您正确设置了您的 View 模型，并且您确定您的 MyData 集合不为 null 或为空，请尝试从您的 xaml 中删除“路径”关键字:

<ListView Margin="8" Height="400" Width="650" 
    ItemsSource="{Binding Path=MyData}">
    <ListView.View>
         <GridView>
             <GridViewColumn Header="ID" Width="Auto" 
                  DisplayMemberBinding="{Binding ID}" >
             </GridViewColumn>
             <GridViewColumn DisplayMemberBinding="{Binding Name}" 
                  Header="Name" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Price}" 
                  Header="Price" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Author}" 
                  Header="Author" Width="100"/>
             <GridViewColumn DisplayMemberBinding="{Binding Catalog}" 
                  Header="Catalog" Width="100"/>
           </GridView>
    </ListView.View>
</ListView>

如果这没有帮助，请检查调试输出并发布它，我们一定会想办法的。
