GridView ItemClick navigate to another page and show details about the clicked item Windows store app

Question

i have a GridView with item from a list of person list, how can i show details of the clicked item in the next page?

in the main page i have used this code

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

and i have used this in the next page

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

I fixed it by changing my code

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

in the next page

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

And in my xaml file i added this

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