WPF拖动窗体栏移动

     // 支持标题栏拖动  
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)  
{  
    base.OnMouseLeftButtonDown(e);  
  
    // 获取鼠标相对标题栏位置  
    Point position = e.GetPosition(gridTitleBar);  
  
    // 如果鼠标位置在标题栏内，允许拖动  
    if (e.LeftButton == MouseButtonState.Pressed)  
    {  
        if (position.X >= 0 && position.X < gridTitleBar.ActualWidth && position.Y >= 0 && position.Y < gridTitleBar.ActualHeight)  
        {  
            this.DragMove();                      
        }  
    }  
}  

这是在代码中重写OnMouseLeftButtonDown函数，

下面是简单的对应区域的窗体拖动事件

 #region 鼠标单击拖动窗体
        private void canvHear_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                this.DragMove();
            }
        } 
        #endregion
