我正在嘗試根據所選的 ListViewItem 更改項目可見性。基本上，ListView 中的每一列在網格上都有兩個項目、一個標簽和一個控件（組合框、日期選擇器、文本框等）。如果選擇 ListViewItem，那么我希望該行中的所有控件都可見，否則標簽應該可見。這是在 UserControl 上，而不是在 Window 上，如果這有什么區別的話。這是我的視圖模型    public class DailyServiceLogsViewModel{     public int DailyServiceLogID { get; set; }    public int EmployeePositionID { get; set; }    public PositionType SelectedEmployeePosition { get; set; }    public List<PositionType> EmployeePositionList { get; set; }    public List<EmployeeSelectionListViewModel> EmployeeList { get; set; }    public EmployeeSelectionListViewModel SelectedEmployee { get; set; }    public string EmployeeName { get; set; }    public string PositionDescription { get; set; }    public DateTime? Date { get; set; }    public string WorkArea { get; set; }    public bool SelectedLog { get; set; }}代碼隱藏            private DBContext _dbContext= new DBContext();            public ObservableCollection<DailyServiceLogsViewModel> DailyServiceLogs { get; set; }            public void OnLoad()            {                _dbContext= new DBContext();                List<EmployeeSelectionListViewModel> employeeList = _dbContext.Employees.Where(emp => emp.Active).Select(employee => new EmployeeSelectionListViewModel { EmployeeID = employee.EmployeeID, EmployeeName = employee.FirstName + " " + employee.LastName }).ToList();                DailyServiceLogs = new ObservableCollection<DailyServiceLogsViewModel>();                foreach (var serviceLog in _dbContext.DailyServiceLogs.Where(d => d.PayPeriodID == CurrentPayPeriod.PayPeriodID).OrderBy(d =>                   }                  ListViewTest.DataContext = this;                  ListViewTest.ItemsSource = DailyServiceLogs;                }我嘗試過使用 DataTriggers，但我對它們不太熟悉
