WPF数据驱动修改绑定 WPF数据驱动修改绑定

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}。
二、代码案例 【WPF数据驱动修改绑定】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; }
