C# DataGridTemplateColumn更新

我正在将一个旧控件修改为WPF。我需要制作一个显示报警列表的数据网格。datagrid的第一列是datagridtemplate列，其中包含一个标志图标和日期。当用户按下按钮时，报警被确认，标志图标必须消失。我使用的是MVVM模式

问题是我似乎无法更新datagridtemplate列中的标志。当我将确认状态从0更改为1时，报警已确认，标志不会消失。当我重新加载控件并再次从服务器获取警报时，该标志不会再次显示，表明其状态实际上已在服务器中更新。因此，不知何故，我的代码正在工作，但我的UI没有得到更新。我还试图以同样的方式更改报警的描述，该列确实得到了更新。MainViewModelBase实现INotifyPropertyChanged

您在setter中设置了_ackStatus，但没有从AlarmEntryViewModel中的getter返回此字段的值。这样做：

private bool _ackStatus;
public bool AckStatus
{
    get
    {
        return _ackStatus;
    }
    set
    {
        _ackStatus = value;
        RaisePropertyChanged(() => AckStatus);
    }
}

或在setter中设置_model.AcknStatus字段：

private bool _ackStatus;
public bool AckStatus
{
    get
    {
        if (_model.AcknStatus == 0)
            return false;
        else
            return true;

    }
    set
    {
        _ackStatus = value;
        _model.AcknStatus = value ? 1 : 0;
        RaisePropertyChanged(() => AckStatus);
    }
}

public class AlarmEntryViewModel : MainViewModelBase
    {
    #region Fields
    private readonly IViewManager _viewManager;

    private string _description;
