问题描述

我正在 Windows Phone 7 中实现 Pivot 控件.

推荐答案

SelectionChanged 是用于检测 Pivot 项目更改的事件.

SelectionChanged is the event to wire up to for detecting Pivot item changes.

正如 kP 所建议的，SelectedIndex/SelectedItem 是您可以访问以查看当前选择了哪个项目的属性.

As kP suggests, SelectedIndex/SelectedItem are the properties you can access to see which item is currently selected.

这是一个示例事件处理程序，用于在每次更改时显示 SelectedIndex.

Here's an example event handler to show the SelectedIndex each time it changes.

    private void thisPivot_SelectionChanged(object sender, SelectionChangedEventArgs e) {
        System.Diagnostics.Debug.WriteLine(thisPivot.SelectedIndex);
    }
