引出需要slider与textbox互相影响互相绑定 “双向绑定”事件驱动private void Slider_ValueChange(object sender, RoutedPropertyChangedEventArgsdouble e) { text1.Text slider.Value.ToString(); text2.Text slider.Value.ToString(); text3.Text slider.Value.ToString(); } private void text1_TextChanged(object sender, TextChangedEventArgs e) { if (double.TryParse(text1.Text, out double result)) slider.Value result; }从我们某种需求产生代码为业务代码 尽可能使UI与业务代码分离StackPanel Slider x:Nameslider Margin5 / TextBox x:Nametext1 Margin5 Height30 Text{Binding ElementNameslider,PathValue}/ TextBox x:Nametext2 Margin5 Height30 Text{Binding ElementNameslider,PathValue}/ TextBox x:Nametext3 Margin5 Height30 Text{Binding ElementNameslider,PathValue}/ /StackPanel
