如何从GridView中的ItemCollection获取项目详细信息

我有一个带有不同元素的GridView页面（ItemExplorer）。每个元素都有两个文本块（名称和描述），它们绑定到一个集合。

我希望当我单击单个元素时，应该打开一个包含项目详细信息（ItemViewer）的新页面，比如名称或描述。。。

我是C#的新手，所以我感谢任何帮助或支持！：）

这是我当前的代码：

ItemExplorer.xaml:

<GridView ItemsSource="{Binding ItemList}">
    <GridView.ItemTemplate>
        <DataTemplate>
            <Border DoubleTapped="GoToItemViewer_DoubleTapped">
                <StackPanel>
                    <TextBlock Name="ItemName" Text="{Binding ItemName}"/>
                    <TextBlock Name="ItemDescription" Text="{Binding ItemDescription}"/>
                </StackPanel>
            </Border>
        </DataTemplate>
    </GridView.ItemTemplate>
</GridView>

ItemExplorer.xaml.cs:

namespace Test001.Pages
{
    public sealed partial class ItemExplorer : Page
    {
        public ItemCollection MyItemCollection;
        public ItemExplorer()
        {
            this.InitializeComponent();
        }
        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
           MyItemCollection = new ItemCollection();
           this.DataContext = MyItemCollection;
        }
        // Go to ItemViewer
        private void GoToItemViewer_DoubleTapped(object sender, DoubleTappedRoutedEventArgs e)
        {
            if (this.Frame != null)
            {
                // SEND THE ITEM DETAILS AS PARAMTER TO ITEMVIEWER
                this.Frame.Navigate(typeof(ItemViewer));
            }
        }
    }
}

ItemCollection.cs

Collectionnamespace Test001.DataSource
{
    public class CollectionFiles: BindableBase
    {
        private ItemCollection _ItemList = new ItemCollection();
        public ItemCollection ItemList
        {
            get { return _ItemList; }
            set { SetProperty(ref _ItemList, value); }
        }
        public CollectionFiles()
        {
            _ItemList.Add(new FileModel()
            {
                ItemName = "ItenName0",
                ItemDescription = "Iten Description0",
            });
            _ItemList.Add(new FileModel()
            {
                ItemName = "ItenName1",
                ItemDescription = "Iten Description1",
            });
            _ItemList.Add(new FileModel()
            {
                ItemName = "ItenName2",
                ItemDescription = "Iten Description2",
            });
            _ItemList.Add(new FileModel()
            {
                ItemName = "ItenName3",
                ItemDescription = "Iten Description3",
            });
        }
    }
}

ItemViewer.xaml.cs

namespace mydox104.Pages
{
    public sealed partial class DocumentViewer : mydox104.Common.LayoutAwarePage
    {
        public DocumentViewer()
        {
            this.InitializeComponent();
        }
        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            // GET THE ITEM DETAILS
            string file_name = e.Parameter as string;
            if (!string.IsNullOrWhiteSpace(file_name))
            {
                pageTitle.Text = file_name;
            }
            else
            {
                pageTitle.Text = e.Parameter.ToString();
            }
        }
    }
}

项目查看器.xaml

<Grid Height="225">
    <TextBlock x:Name="Item-Name" Text=""/>
    <TextBlock x:Name="Item-Description" Text=""/>
</Grid>

<GridView IsItemClickEnabled="True" ItemClick="ItemClicked" ItemsSource="{Binding ItemList}">

private void ItemClicked(object sender, ItemClickEventArgs e)
{
    var clickedItem = e.ClickedItem as ItemCollection;
    if (clickedItem != null )
    {
       this.Frame.NavigateTo(typeof(ItemViewer), clickedItem);
    }
}

 protected override void OnNavigatedTo(NavigationEventArgs e)
{
 ItemCollection myElement = e.Parameter as ItemCollection;
 ...
}
