WP7WrapPanel

大家好，又见面了，我是你们的朋友全栈君。

WrapPanel:这个面板控件主要是通过Orientation属性设置包含在控件是的元素从左至右或从上至下依次安排位置，当元素超过该控件边缘时，它们将会被自动转至下一行或列。此控件一般用于文本布局、拾色器、图片等。需要加载System.Windows.Controls.Toolkit.dll

Xaml代码为：
        <Grid x:Name=”ContentPanel” Grid.Row=”1″ Margin=”12,0,12,0″>
            <toolkit:WrapPanel Height=”504″ HorizontalAlignment=”Left” Margin=”9,78,0,0″ Name=”wrapPanel1″ VerticalAlignment=”Top” Width=”441″ />
            <Button Content=”清空” Height=”72″ HorizontalAlignment=”Left” Name=”button1″ VerticalAlignment=”Top” Width=”101″ Click=”button1_Click” />
            <Button Click=”OnAdd” Content=”+1″ Tag=”1″ Height=”72″ HorizontalAlignment=”Left” Margin=”107,0,0,0″ Name=”button2″ VerticalAlignment=”Top” Width=”101″ />
            <Button Click=”OnAdd” Content=”+5″ Height=”72″ HorizontalAlignment=”Left” Margin=”228,0,0,0″ Name=”button3″ Tag=”5″ VerticalAlignment=”Top” Width=”101″ />
            <Button Click=”OnAdd” Content=”+8″ Height=”72″ HorizontalAlignment=”Left” Margin=”355,0,0,0″ Name=”button4″ Tag=”8″ VerticalAlignment=”Top” Width=”101″ />
        </Grid>
CS代码为：
       Random rnd = new Random();
        private void button1_Click(object sender, RoutedEventArgs e)
        {//清空
            this.wrapPanel1.Children.Clear();
        }
        private void OnAdd(object sender, RoutedEventArgs e)
        {//根按按钮的Tag属性添加内容
            int count = Int32.Parse((string)((FrameworkElement)sender).Tag);

            while (count– > 0)
            {

                AddItem();
            }
        }

        private void AddItem()
        {//添加
            Border b = new Border()
            {

                Width = 100,
                Height = 100,
                Background = new SolidColorBrush(Color.FromArgb(255, (byte)rnd.Next(256), (byte)rnd.Next(256), (byte)rnd.Next(256))),
                BorderThickness = new Thickness(2),
                Margin = new Thickness(8)
            };

            b.BorderBrush = (SolidColorBrush)Resources[“PhoneForegroundBrush”];

            //b.Tap += OnTapped;

            //注册移除事件
            GestureListener listener = GestureService.GetGestureListener(b);
            listener.Tap += new EventHandler<GestureEventArgs>(WrapPanelSample_Tap);

            wrapPanel1.Children.Add(b);
        }

        void WrapPanelSample_Tap(object sender, GestureEventArgs e)
        {//移除事件
            Border b = (Border)sender;
            wrapPanel1.Children.Remove(b);
        }

        //void OnTapped(object sender, System.Windows.Input.GestureEventArgs e)
        //{

           // Border b = sender as Border;
            //if (null != b)
            //{

                //wrapPanel.Children.Remove(b);
            //}

//}
