Windows 8 C# GridView e.ClickedItem

我有一个包含项目的GridView和一个包含有关GridView中特定项目详细信息的数组。我想获得点击项目的索引，我试图使用我之前使用的ListView相同的代码:

private void GridView1_ItemClick(object sender, ItemClickEventArgs e)
{
    int test = GridView1.Items.IndexOf(e.ClickedItem);
}

当我调试我的代码时，int test将始终具有值-1。我不知道为什么这不起作用，我希望你们中的一个能做到。

编辑:感谢所有的回复!这里是一些额外的信息:我已经禁用了SelectionMode，因为我只想捕获ClickedItem的索引。我想知道索引，因为它与我的额外信息数组相连。

由于我的SelectionMode设置为"None"，我无法捕获SelectedItem/SelectedIndex。我尝试启用它们，但再次收到值"-1"。

编辑#2:我没有设置任何ItemSource，因为我手动添加项目。这就是问题所在吗?我的ListView没有问题，没有ItemSource。

编辑# 3:

c#代码:

TextBlock content_textblock = new TextBlock();
content_textblock.Width = 250;
content_textblock.Text = total;
content_textblock.TextWrapping = TextWrapping.Wrap;
content_textblock.Foreground = (SolidColorBrush)Application.Current.Resources["ListViewItemOverlayForegroundThemeBrush"];
content_textblock.Style = (Style)Application.Current.Resources["CaptionTextStyle"];
content_textblock.LineHeight = 30;
content_textblock.Padding = new Thickness(5, 0, 10, 15);
content_textblock.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
content_textblock.Arrange(new Rect(0, 0, content_textblock.DesiredSize.Width, content_textblock.DesiredSize.Height));

StackPanel content_stackpanel = new StackPanel();
content_stackpanel.Margin = new Thickness(0, 250 - content_textblock.ActualHeight, 0, 0);
content_stackpanel.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Top;
content_stackpanel.Height = content_textblock.Height;
content_stackpanel.Width = 250;
content_stackpanel.Background = (SolidColorBrush)Application.Current.Resources["ListViewItemOverlayBackgroundThemeBrush"];
content_stackpanel.Children.Add(content_textblock);

ImageBrush content_brush = new ImageBrush();
content_brush.ImageSource = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri("http://ic.tweakimg.net/ext/i/thumbs_fpa_small/1357208162.jpeg")); //it is a placeholder, haha
GridView1.Items.Add(new GridViewItem { Background = content_brush, Content = content_stackpanel, Width = 250, Height = 250 });

XAML:

<GridView x:Name="GridView1" Margin="0,29,0,0" Grid.Row="2" SelectionMode="None" ItemClick="GridView1_ItemClick" IsItemClickEnabled="True"/>

private void GridView1_ItemClick(object sender, ItemClickEventArgs e)
{
    int test = GridView1.Items.IndexOf((e.ClickedItem as FrameworkElement).Parent);
}

var item=GridView1.SelectedItem;

var index= GridView1.SelectedIndex;
