silverlight, 双击事件

 Silverlight 没有提供双击事件，所以需要通过判断两次点击的时间来模拟双击事件

下面的代码，做个参考。

cellBtn.Click += new RoutedEventHandler(cellBtn_Click);
                        //cellBtn.MouseLeftButtonUp += new MouseButtonEventHandler(cellBtn_MouseLeftButtonUp);
                        //cellBtn.MouseLeftButtonDown += new MouseButtonEventHandler(cellBtn_MouseLeftButtonUp);
                        //cellBtn.MouseEnter += new MouseEventHandler(cellBtn_MouseLeftButtonUp);

void cellBtn_MouseLeftButtonUp(object sender, MouseEventArgs e)
        {

            DateTime b = DateTime.Now;
            long c = TimeDiff(b, _timeLastLeftButtonUp);
            _timeLastLeftButtonUp = b;
            if (c < 300)
            {
                HtmlWindow html = HtmlPage.Window;
                html.Alert("双击");
            }
            else
            {

            }
        }


        void cellBtn_Click(object sender, RoutedEventArgs e)
        {
            //string neDetail = (sender as Button).Content.ToString();

            //HtmlWindow html = HtmlPage.Window;
            //html.Alert(neDetail); 

            
        }

        /// <summary>
        /// 计算时间差
        /// </summary>
        /// <param name="t">时间1</param>
        /// <param name="t2">时间2</param>
        /// <returns>返回值：时间差(毫秒为单位)</returns>
        private long TimeDiff(DateTime t, DateTime t2) 
        {
            long lReturn = -1;
            System.TimeSpan NowValue = new TimeSpan(t.Ticks);
            System.TimeSpan TimeValue = new TimeSpan(t2.Ticks);
            System.TimeSpan DateDiff = TimeSpan.Zero;
            try
            {
                //计算时间差
                //DateDiff = TimeValue.Subtract(NowValue).Duration();
                DateDiff = NowValue.Subtract(TimeValue);
                int hours = DateDiff.Hours;
                int minutes = DateDiff.Minutes;
                int seconds = DateDiff.Seconds;
                int milliseconds = DateDiff.Milliseconds;

                string TimeDiff = hours.ToString() + ":"
                    + minutes.ToString() + ":"
                    + seconds.ToString() + "."
                    + milliseconds.ToString();
                //Program.log.WriteLog("时间差："+TimeDiff, System.DateTime.Now.ToString(), Orid.Log.LogManagerBase.LogMode.logNormal);
                

                lReturn = hours * 3600 * 1000
                    + minutes * 60 * 1000
                    + seconds * 1000
                    + milliseconds;
            }
            catch (Exception e)
            {
                throw new Exception(e.Message);
            }
            return lReturn;
        }
