如何从ListVIew中选择项目

Question

好的,我希望你能理解我......

我有一个listView.ListView填充了一个数据集合(列表列表),但ListView中的每个项目都有相同的模板(边框,网格,边框,文本块),因此,当我选择一个模板时,如何获取文本块的text属性项目？

xmlns:vmSegments="using:EC_UsuarioWin8.ViewModels"


<Page.Resources>
   <DataTemplate x:Key="ItemTemplateStyleSegment">
        <Border  Margin="-10,0,0,0" Background="White" >
            <Grid Height="120" Width="200">
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <Border Grid.Row="0">
                    <Image Source="{Binding SegmentImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="10"/>
                </Border>
                <Border Grid.Row="1" >
                    <TextBlock Text="{Binding SegmentName}" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="#FFE0241B" FontSize="20" />
                </Border>
            </Grid>
        </Border>
    </DataTemplate>
</Page.Resources>

<Grid>
   <Grid.Resources>
                <vmSegments:ViewModelSegments x:Key="SegmentCollectionVM" x:Name="SegmentCollectionVM"/>
   </Grid.Resources>

<ListView x:Name="ListVIewSegments" ItemsSource="{Binding Source={StaticResource SegmentCollectionVM}, Path= SegmentList}" Grid.Row="1" Margin="20" ItemContainerStyle="{StaticResource ListViewSItemtyleECFood}" ItemTemplate="{StaticResource ItemTemplateStyleSegment}" SelectionChanged="ListViewSegments_SelectionChanged">
</ListView>

</Grid>

我的类ViewModelSegments:

public class ViewModelSegments : BindableBase
{

    private SegmentsCollection _segmentList = new SegmentsCollection();
    public SegmentsCollection SegmentList
    {
        get { return _segmentList; }
        set { SetProperty(ref _segmentList, value); }
    }
}

我的班级SegmentsCollection:

public class SegmentsCollection: ObservableCollection<Segment>
{

}

我的课程部分:

public class Segment : BindableBase
{
    //Propiedad SegmentName
    private string Name;
    public string SegmentName
    {
        get { return Name; }
        set { SetProperty(ref Name, value); }
    }

    //Propiedad SegmentPicture
    private Uri image;
    public Uri SegmentImage
    {
        get { return image; }
        set { SetProperty(ref image, value); }
    }

}

使用ItemClick事件ListView

//Here sender is your list view
public delegate void ItemClickEventHandler(object sender, ItemClickEventArgs e)
{
   ListView lv = sender as ListView;
   Segment seg = e.ClickedItem as Segment;

   if (lv != null)
   {
      //Use your lv if you want to
   }

   if (seg != null)
   {
      string name = seg. SegmentName;
   }
}

更新

private void ListView_SelectionChanged(object sender,SelectionChangedEventArgs e)
{
    lv.SelectedItem; // If you have set SelectionMode="Single" then it will do
    //the trick but if you set SelectionMode="Multiple" then it's the first
    //selected item

    lv.SelectedItems; // It will give you the selected list of item view models

    e.AddedItems; //This will give you the added items. As it is a list so can
    //be multiple but when it can be multiple I don't know that case.

    e.RemovedItems; //Similarly removed items
}
