WPF弹出带蒙板的消息框
先看看效果图
思路
拿到父级窗体的内容,放入一个容器里,再在容器里放入一个半透明层.将整个容器赋给父级窗体的内容.
关闭时反向操作.
代码
消息窗弹出时
/// <summary> /// 弹出消息框 /// </summary> /// <param name="message">消息</param> /// <param name="owner">父级窗体</param> public static void ShowDialog(string message, Window owner) { //蒙板 Grid layer = new Grid() { Background = new SolidColorBrush(Color.FromArgb(128, 0, 0, 0)) }; //父级窗体原来的内容 UIElement original = owner.Content as UIElement; owner.Content = null; //容器Grid Grid container = new Grid(); container.Children.Add(original);//放入原来的内容 container.Children.Add(layer);//在上面放一层蒙板 //将装有原来内容和蒙板的容器赋给父级窗体 owner.Content = container; //弹出消息框 MessageBox box = new MessageBox() { Owner = owner }; box.tbc_message.Text = message; box.ShowDialog(); }
消息框关闭时
/// <summary> /// 窗体关闭事件 /// </summary> private void Window_Closed(object sender, EventArgs e) { //容器Grid Grid grid = this.Owner.Content as Grid; //父级窗体原来的内容 UIElement original = VisualTreeHelper.GetChild(grid, 0) as UIElement; //将父级窗体原来的内容在容器Grid中移除 grid.Children.Remove(original); //赋给父级窗体 this.Owner.Content = original; }
