wpf用通知属性更新动态创建的按钮显示文本

Question

1.自定义通知类

 
 public class NotifyBase : INotifyPropertyChanged
{
        public event PropertyChangedEventHandler PropertyChanged;
 
        public void NotifyChanged([CallerMemberName] string propName = "")
{
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
}
}

2 .创建动态按钮

  Random random = new Random();
            for (int i = 0; i < 3; i++)
{
                lstBtn.Add(new DataGridItemModel2 { Name = "btn测试-" + i.ToString("00"), Age = random.Next(18, 90), Value = random.Next(30, 120).ToString() });
}
            foreach (var actor in lstBtn)
{
CreateDynamicButton(actor.Name, actor.Age);
}
public void CreateDynamicButton(string btnText, int actIndepth)
{
            Button btn = new Button();
btn.Content = btnText;
            btn.Margin = new Thickness(3, 0, 0, 0);
            btn.Padding = new Thickness(3, 0, 0, 0);
            //btn.GradientMode = System.Drawing.Drawing2D.LinearGradientMode.Vertical;
            //btn.BackColor = Color.FromKnownColor(KnownColor.Control);          
btn.Cursor = Cursors.Hand;
            btn.Height = 70;
            btn.Width = 300;
btn.Tag = actIndepth;
grid.Children.Add(btn);
}
 
   
    public class DataGridItemModel2:NotifyBase
{
        private string _name;
 
        public string Name
{
            get { return _name; }
            set { _name = value; this.NotifyChanged(); }
}
 
 
        private int _age;
 
        public int Age
{
            get { return _age; }
            set { _age = value; this.NotifyChanged(); }
}
 
 
        public string Value
{
            get;
            set;
}
}
}

3.试图更改动态创建的按钮显示文本，界面不能更
MainWindow.lstBtn[0].Name = "test";

Answer 1

用异步线程尝试定位按钮name给name.content赋值

Answer 2

那这样不是绑定了

Answer 3

 
GridViewColumn gridViewColumn = new GridViewColumn() { Header = viewColumns[i].Name, Width = viewColumns[i].Width, DisplayMemberBinding = new System.Windows.Data.Binding($"Data[{i}]") };
                DisplayView.Columns.Add(gridViewColumn);

上面是我创建动态显示表头并绑定属性的方法，可参考
