上一次做分頁控件的時候設(shè)想的把分頁設(shè)置類保存到數(shù)據(jù)庫，后來覺得的沒必要這么做。分頁的包括htmlhelper 數(shù)據(jù)模型和分頁設(shè)置都在PagerExtensions.cs中，不跟數(shù)據(jù)庫發(fā)生關(guān)系，當其他項目中需要用分頁的時候直接拷貝這個文件過去就可以直接用。欄目中的分頁設(shè)置直接在欄目中添加字段然后在控制器中new一個PagerConfig，然后設(shè)置響應值。

由于欄目的模型字段發(fā)生變換 添加 修改欄目信息的視圖和action也要進行相應修改。

修改ManageAdd(Category category)，主要是首先驗證選定的父欄目是否存在。根據(jù)選定的欄目類型驗證相應的字段是否輸入，設(shè)置無關(guān)字段為null

下面就該欄目詳細信息的視圖ManageDetails.cshtml，基本與ManageAdd視圖。 然后修改更新欄目信息action [ManageUpdate(Category category)]。 在這里1、要檢查父欄目是不是其本身或其子欄目，如果是添加驗證未通過信息。2、根據(jù)選定的欄目類型驗證相應的字段是否輸入，設(shè)置無關(guān)字段為null。3、如果父欄目發(fā)生更還，更改其本身及其子欄目的ParentPath。
