привет, я определяю настраиваемую полосу выполнения в wpf (Xaml) и с помощью Code-Behind, и для реализации этого я использую INotifyPropertyChanege, но не работал онлайн, когда ставил его, например:
enter code here
CustomizeProgressBar c=new CustomizeProgressBar();
c.Maximum=100;
c.Minimum=0;
for(int i=0;i<100;i++){
Thread.sleep(1000);
c.Value++;
}
enter code here
но если поставить его увеличить значение в событии нажатия кнопки, его работа, но это не бесполезно, например:
enter code here
public void Button_Click(obj sender,event arg e){
c.Value++;
}
