问题描述

我使用的是 FlipView 建设一个照片应用程序。在BottomAppBar,我放在的ListView 所有的图像,以便能够在 FlipView 时查看图像I双击它,在的ListView 并获得中显示的图像 FlipView 的ListView选择(如分页)。

I'm building a Photo app using a FlipView. In the BottomAppBar, I placed a ListView of all the images to be able to view the image in the FlipView when I click it in the ListView and get the image displayed in the FlipView, selected in the ListView (like a Pagination).

listView.selectionChanged 时,我做了code,显示在图像的 FlipView 当我在 ListView中选中它。这里是code:

In the listView.selectionChanged event, I made the code that shows the image in the FlipView when I select it in the ListView. Here is the code:

    private void listView_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            string CurrentViewState = ApplicationView.GetForCurrentView().Orientation.ToString();
            int IndicatorIndex = listView.SelectedIndex;

            GoToPage(CurrentViewState, IndicatorIndex);
        }

    private void GoToPage(string CurrentViewState, int IndicatorIndex)
        {
            if (CurrentViewState == "Portrait")
            {
                flipView1.SelectedIndex = IndicatorIndex;
            }
            else if (CurrentViewState == "Landscape")
            {
                if (IndicatorIndex % 2 == 0)
                    flipView1.SelectedIndex = IndicatorIndex / 2;
                else
                {
                    if (IndicatorIndex == 1)
                        flipView1.SelectedIndex = 1;
                    else
                        flipView1.SelectedIndex = (IndicatorIndex + 1) / 2;
                }
            }
        }

现在,当我需要的 listView.SelectedIndex 根据修改 flipView.SelectedIndex

Now when I need to change the listView.SelectedIndex according to the flipView.SelectedIndex

listView.SelectedIndex = flipView.SelectedIndex

我有一个例外:

An exception of type 'System.ArgumentException' occurred in eBookApp.exe but was not handled in user code. Additional information: Value does not fall within the expected range.

我需要能够获得在 FlipView ,选择并scrollAt它在的ListView ...

I need to be able to get the same image selected in the FlipView, selected and scrollAt it in the ListView...

推荐答案

我最终使它通过增加工作我的 FlipView

I ended up making it work by adding to my FlipView:

SelectedIndex="{Binding Path=SelectedIndex, ElementName=listView1, Mode=TwoWay}"

和我的的ListView

SelectedIndex="{Binding Path=SelectedIndex, ElementName=flipView1, Mode=TwoWay}"

他们都的SelectedIndex 称对方!
