さまざまな要素 (ItemExplorer) を持つ GridView ページがあります。各要素には 2 つの TextBlocks (名前と説明) があり、コレクションにバインドされています。
単一の要素をクリックすると、名前や説明などのアイテムの詳細 (ItemViewer) を含む新しいページが開かれるようにしたい...
私はC#が初めてなので、助けやサポートに感謝します! :)
これは私の現在のコードです:
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();
}
}
}
}
ItemViewer.xaml
<Grid Height="225">
<TextBlock x:Name="Item-Name" Text=""/>
<TextBlock x:Name="Item-Description" Text=""/>
</Grid>
