silverlight创建新的控件——一个简单的弹出菜单

照旧，直接贴代码

<UserControl

    d:DesignWidth="200" d:DesignHeight="480">

    <Grid x:Name="LayoutRoot">
        <Grid.Resources>
            <Storyboard x:Name="hide">
                <DoubleAnimation Duration="00:00:01" From="0" To="-190" 

                                 Storyboard.TargetName="tt" Storyboard.TargetProperty="X"/>

            </Storyboard>
            <Storyboard x:Name="show">

            </Storyboard>
        </Grid.Resources>

        </Grid.ColumnDefinitions>
        
        <StackPanel Grid.Column="0">
            <TextBlock Text="模拟" HorizontalAlignment="Center" Margin="0,10,0,0"/>

            <TranslateTransform x:Name="tt" X="0"/>
        </Grid.RenderTransform>
    </Grid>
</UserControl>

　　 ShowMenu.xaml.cs

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace ControlTemplate
{
    public partial class ShowMenu : UserControl
    {
        private bool isShow = true;
        public ShowMenu()
        {
            // 为初始化变量所必需
            InitializeComponent();
        }

        private void Rectangle_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            if (isShow)
            {
                hide.Begin();
            }
            else
            {
                show.Begin();
            }
            isShow = !isShow;
        }
    }
}

　　

很简单吧
