repeater 控件是一個很靈活的東東，本人在程序開發中就最愛用到它了！！！
很多朋友應該在使用 VS2005 自帶的 日歷控件的時候 都發現或多或少的 不能滿足自己的特殊需求
這個實例看似很簡單 但如果能夠家裡改善 將能很好的運用到自己的程序當中（至少比用JS寫個控件簡單方便，還能很好的很數據庫關聯開發），本代碼只粘貼出了日歷的實現，實際上我用到了四個repeater 的嵌套 實現的是一個日程管理的系統， 剩下的和數據庫有關聯，所以刪掉了！ 希望對想使用日歷控件的朋友有一定的幫助，注釋寫的很清楚了，朋友們可以隨便改動 (程序有注釋的，希望大家粘貼到VS 2005 中去看 很直觀 很清楚的)
