Question

有没有办法获取WPF工具包自动完成框下拉列表中当前显示的项目数？

Answer 1

或者你甚至可以这样做并避免循环：

private void AutoCompleteBox_Populated(object sender, PopulatedEventArgs e)
{
   int count = ((ReadOnlyCollection<object>)e.Data).Count;
}

Answer 2

处理Populated事件：

private void AutoCompleteBox_Populated(object sender, PopulatedEventArgs e)
{
    int count = 0;
    foreach (var item in e.Data)
        count++;

    string text = count + " items shown!";
}
