GridView 项目单击导航到另一个页面并显示有关单击的项目 Windows 应用商店应用的详细信息

Question

我有一个GridView，其中包含人员列表中的项目，如何在下一页显示单击的项目的详细信息？

在主页中，我使用了此代码

Private Sub itemGridView_ItemClick(sender As Object, e As ItemClickEventArgs) Handles itemGridView.ItemClick
    Me.Frame.Navigate(GetType(BlankPage1), e.ClickedItem)
End Sub

我在下一页中使用了这个

Private Sub NavigationHelper_LoadState(sender As Object, e As Common.LoadStateEventArgs)
    Dim n As Person = TryCast(e.NavigationParameter, Person)
    txt.Text = n.Name
End Sub

Answer 1

我通过更改代码来修复它

Private Sub itemGridView_ItemClick(sender As Object, e As ItemClickEventArgs) Handles itemGridView.ItemClick
    Dim person As Person = DirectCast(e.ClickedItem, Person)
    Me.Frame.Navigate(GetType(BlankPage1), person)
End Sub

在下一页

Private Sub NavigationHelper_LoadState(sender As Object, e As Common.LoadStateEventArgs)
    Dim person As Person = DirectCast(e.NavigationParameter, Person)
    Me.DefaultViewModel("Details") = person
End Sub

在我的 xaml 文件中，我添加了这个

DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}"
