WPF后台创建控件和绑定

WPF后台创建控件和绑定

一、创建一个类：

public class MyData : INotifyPropertyChanged
{
    private string text;
    public string Text
    {
        get { return text; }
        set 
        { 
            text = value;
            OnPropertyChanged(nameof(Text));
        }
    }
 
    public event PropertyChangedEventHandler PropertyChanged;
 
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

创建控件并绑定数据：

public partial class MainWindow : Window
{
    private MyData myData = new MyData();
 
    public MainWindow()
    {
        InitializeComponent();
 
        // 创建TextBox控件
        TextBox textBox = new TextBox();
 
        // 绑定数据源
        textBox.SetBinding(TextBox.TextProperty, new Binding("Text") { Source = myData });
 
        // 添加到布局容器中
        this.Content = textBox;
 
        // 或者你也可以将其添加到已有的布局面板中
        // myGrid.Children.Add(textBox);
 
        // 测试数据绑定
        myData.Text = "Hello, WPF!";
    }
}
