c#devexpress GridContorl添加进度条 c#

文章图片

demo 的实现图
下边是步骤和代码
1定义时钟事件,定时的增加进度条的增量.
【c#devexpress GridContorl添加进度条】2:添加进度条
3; 定义字段属性

class JinduModel : INotifyPropertyChanged { private int _jindu; public int jindu { get { return _jindu; } set { _jindu = value; OnPropertyChanged("jindu"); } } public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string name) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name)); }}
