简介 WPF数据驱动修改绑定_实用技巧_

一、简介

在XAML文件中我们创建了一个TextBlock 和一个Slider。2个控件。我们把TextBlock的Text属性（用于显示文本的属性）设置为{Binding Intelligence}。把Slider的Value属性（滑块的当前值）设置为{Binding Intelligence}。

XMAL:

后台逻辑：

 public partial class MainWindow : Window { Person p; public MainWindow() { InitializeComponent(); p = new Person(); Binding binding = new Binding(); binding.Source = p; binding.Mode = BindingMode.TwoWay; binding.Path = new PropertyPath("Name"); BindingOperations.SetBinding(tb_inputName, TextBox.TextProperty, binding); this.DataContext = p; } private void AlertText_Click(object sender, RoutedEventArgs e) { p.Name = "点击按钮后>>>>"; } } public class Person : INotifyPropertyChanged { private double _intelligence; public double Intelligence { get { return _intelligence; } set { _intelligence = value; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Intelligence")); } } private string _name; public string Name { get { return _name; } set { _name = value; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Name")); } } public event PropertyChangedEventHandler PropertyChanged; }
