Question

由于Windows手机表单不是模态的， 如何获得在ColorPicker.xaml中设置的所选颜色的值？

    Dim FirstBand As Res.Color
    Dim SecondBand As Res.Color

       Private Sub TextBlock_Tap(sender As Object, e As GestureEventArgs)
            NavigationService.Navigate(New Uri("/ColorPicker.xaml", UriKind.Relative))
            FirstBand = ColorPicker.SelectedColor
            txtFisrt.Text = FirstBand.ToString
        End Sub

        Private Sub TextBlock1_Tap(sender As Object, e As GestureEventArgs)
            NavigationService.Navigate(New Uri("/ColorPicker.xaml", UriKind.Relative))
            SecondBand = ColorPicker.SelectedColor
            txtSecond.Text = SecondBand.ToString
        End Sub
