从xaml的列表框中选择listitem

Question

我有一个列表框，列表框中的数据正在通过sqlite数据库填充。

XAML

<ListBox x:Name="listBoxobj" Background="Transparent" Margin="6" Height="auto" BorderThickness="2" MaxHeight="580" Grid.Row="1" SelectionChanged="listBoxobj_SelectionChanged"> 
    <ListBox.ItemTemplate> 
     <DataTemplate> 
      <Grid Width="330" Height="100" > 
       <Border Margin="5" BorderBrush="White" BorderThickness="1"> 
        <Grid> 
         <Grid.RowDefinitions> 
          <RowDefinition Height="Auto"/> 
          <RowDefinition Height="Auto"/> 
         </Grid.RowDefinitions> 
         <Grid.ColumnDefinitions> 
          <ColumnDefinition Width="50" /> 
          <ColumnDefinition Width="*" /> 
          <ColumnDefinition Width="100" /> 
         </Grid.ColumnDefinitions> 
         <CheckBox Name="Option1CheckBox" Grid.Row="0" Grid.Column="0" IsChecked="{Binding _isComplete}" VerticalAlignment="Center" Margin="5,0,0,0" /> 
         <TextBlock x:Name="NameTxt" Grid.Row="0" Grid.Column="1" TextWrapping="Wrap" Text="{Binding Name}" VerticalAlignment="Center" HorizontalAlignment="Left" FontSize="22" Foreground="White"/> 
         <TextBlock x:Name="Age" Grid.Row="1" Grid.Column="1" TextWrapping="Wrap" VerticalAlignment="Center" HorizontalAlignment="Left" Foreground="White" FontSize="22" Text="{Binding Age}" /> 
         <Button Grid.Row="0" Grid.Column="2" x:Name="deleteTaskButton" BorderThickness="0" Margin="0" Click="deleteTaskButton_Click" Height="18"> 
          <Image Source="/Assets/delete.png"/> 
         </Button> 
        </Grid> 
       </Border> 
      </Grid> 
     </DataTemplate> 
    </ListBox.ItemTemplate> 
</ListBox> 

当deleteTaskButton用户点击它存在于每个列表项中，ListBoxItem的数据应该从列表中删除，并移动到另一个出现在接下来的枢轴表page.How我可以这样做吗？ 当我点击删除按钮时，列表没有被选中，但删除图标被选中。

因为没有关于列表视图中包含的数据的数据类型的信息。我已经写下了你的deleteTaskButton_Click方法应该看起来如何。与第二listbox

private void deleteTaskButton_Click(object sender, RoutedEventArgs e) 
    { 
     var dataContext = (sender as Button).DataContext as YourDataType; 
     if (dataContext != null) 
     { 
      //now you have the item that was clicked to delete. 
      var DeleteFromDelete = listBoxobj.ItemsSource as ICollection<YourDataType>; 
      if (DeleteFromDelete != null) 
      { 
       //this removes the item to be removed from the currently viewing listview. 
       DeleteFromDelete.Remove(dataContext); 

       //now add the item that was deleted into the other listview. 
       var TobeAddedIntoList = secondListBoxobj.ItemsSource as ICollection<YourDataType>; 
       if (TobeAddedIntoList != null) 
        TobeAddedIntoList.Add(dataContext); 
      } 
     } 
    }
