推荐答案

我在想你使用DataGridView或类似的来显示您的数据吗?如果是这样，我将确保您要修改的对象实现INotifyPropertyChanged接口.

E.G.

I''m thinking that you are using a DataGridView or similar to show your data? If so I would make sure that the object that you are modifying implements the INotifyPropertyChanged interface.

E.G.

class User : INotifyPropertyChanged
{
    protected virtual void SendPropertyChanged(String propertyName)
    {
        if ((this.PropertyChanged != null))
        {
            this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    private int id;
    public int ID
    {
        get { return id; }
        set
        {
            if(id != value)
            {
                id = value;
                idmodified = DateTime.Now;
                SendPropertyChanged("ID");
            }
        }
    }

    private DateTime idmodified;
    public DateTime IDModified
    {
        get {return idmodified;}
        set
        {
            if(idmodified != value)
            {
                idmodified = value;
                SendPropertyChanged("IDModified");
            }
        }
    }
}

然后，当更改DateTime并相应更新时，将通知您DataGridView控件.

Then you DataGridView control will be informed when the DateTime is changed and update accordingly.
