C# 实现任意控件的随意拖动
目的实现窗体里面的所有控件可以随意拖动
C#布局代码如下：
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows;using System.Windows.Controls;using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;namespace DragLabel{ /// <summary> /// MainWindow.xaml 的交互逻辑 /// </summary> public partial class MainWindow : Window { bool IsMouseDown = false; Point mousePoint; object mouseCtrl = null; public MainWindow() { InitializeComponent(); } private void Window_MouseMove(object sender, MouseEventArgs e) { if (IsMouseDown) { if (e.LeftButton == MouseButtonState.Pressed) { Point theMousePoint = e.GetPosition(this.canvas1); Canvas.SetLeft((UIElement)mouseCtrl, theMousePoint.X - (mousePoint.X - Canvas.GetLeft(((UIElement)mouseCtrl)))); Canvas.SetTop((UIElement)mouseCtrl, theMousePoint.Y - (mousePoint.Y - Canvas.GetTop(((UIElement)mouseCtrl)))); mousePoint = theMousePoint; } } } private void Window_MouseUp(object sender, MouseButtonEventArgs e) { if (IsMouseDown) { IsMouseDown = false; } } private void label1_MouseDown(object sender, MouseButtonEventArgs e) { if (e.LeftButton == MouseButtonState.Pressed) { IsMouseDown = true; mousePoint = e.GetPosition(this.canvas1); mouseCtrl = sender; } } private void stackPanel1_MouseDown(object sender, MouseButtonEventArgs e) { if (e.LeftButton == MouseButtonState.Pressed) { IsMouseDown = true; mousePoint = e.GetPosition(this.canvas1); mouseCtrl = sender; } } }}
