A PageFunction<T> calls OnReturn(ReturnEventArgs<T>) to return to the caller, passing a return value via a ReturnEventArgs<T> object.

The following example shows how to call OnReturn.
void doneButton_Click(object sender, RoutedEventArgs e)
{
// Complete the page function and return data of type T
OnReturn(new ReturnEventArgs<String>(this.pageFunctionData.Text));
}
Private Sub doneButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
' Complete the page function and return data of type T
OnReturn(New ReturnEventArgs(Of String)(Me.pageFunctionData.Text))
End Sub
OnReturn is called by a PageFunction<T> to initiate a navigation to the calling page.
This causes the Return event to be raised, in order for the calling page to:
Detect when the PageFunction<T> has returned.
Retrieve the return value from the PageFunction<T>.
