我有一个包含4个枢轴项目的应用程序.在枢轴项目2中进行特定选择时，我将不得不隐藏枢轴项目3.在枢纽项目4中做出另一个选择时，我将不得不取消隐藏枢纽项目3，但其位置应在item2与 仅限item4.

I have an application with 4 pivot items. On making a particular selection in pivot item2, i will have to hide the pivot item3. On making another selection in pivot item4, i will have to unhide the pivot item3, but its position should be between item2 and item4 only.

我尝试添加和删除，但我只能在末尾而不是在item2和item4之间添加数据透视项.

I tried adding and removing but i was only able to add the pivot item at the end and not in between item2 and item4.

我的问题有解决方案吗?

Is there any solution for my problem?

推荐答案

这两个按钮单击处理程序将在索引处插入/删除PivotItem. = 1;

These two button click handlers will do insert/remove PivotItem at index = 1;

但是我认为这不是最好的主意.

But I think this is not the best idea to do it.

private PivotItem savedPivotItem = null; private void RemoveSecondPivotItem_Click(object sender, RoutedEventArgs e) { savedPivotItem = MainPivot.Items[1] as PivotItem; MainPivot.Items.RemoveAt(1); } private void AddSecondPivotItem_Click(object sender, RoutedEventArgs e) { if (savedPivotItem != null) { MainPivot.Items.Insert(1, savedPivotItem); } }

此致.
