C# winfrom 中自定義的翻頁控制項（自己設計）

1.主要是使用控制項綁定點擊事件用到的控制項分別為picturebox lable 上一頁pbPage_Prev 下一頁 pbPage_Next 首頁 pbPage_Begin 尾頁pbPage_End 是picturebox控制項加背景圖 “第頁/ 共頁” 是一個lable “labPageInf ...
1.主要是使用控制項綁定點擊事件
用到的控制項分別為picturebox lable 上一頁pbPage_Prev 下一頁 pbPage_Next 首頁 pbPage_Begin 尾頁pbPage_End 是picturebox控制項加背景圖
“第頁/ 共頁” 是一個lable “labPageInfo” 在lable上面加了一個隱藏的textbox 控制項 “txtPageInfo”
2.將這個翻頁的功能單獨寫在用戶控制項 ucPageTurn 裡面然後在每個頁面直接應用就可以了
下麵只是把ucPageTurn寫了出來
還需要在winform頁面上應用上
