相关疑难解决方法(0)

在使用C#4.0/C#2.0的WinForms中,如果控件的可见字段为false,则无法绑定到控件:

this.checkBox_WorkDone.DataBindings.Add("Visible", WorkStatus, "Done");

我可以确认绑定已成功添加到控件的数据绑定列表中,但如果我更改绑定对象(WorkStatus),则不会发生任何事情.

这就是WorkStatus的样子:

public class WorkStatus : INotifyPropertyChanged
{
    private Boolean _done;
    public Boolean Done
    {
        get { return _done; }

        set
        {
            if (_done == value) return;

            _done = value;

            // fire event
            RaisePropertyChanged("Done");
        }
    }

    private Int32 _time;
    public Int32 Time
    {
        get { return _time; }

        set
        {
            if (_time == value) return;

            _time = value;

            // fire event
            RaisePropertyChanged("Time");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void RaisePropertyChanged(String propertyName)
    {
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    } …
