DevExpress，GridControl如何添加自定義列，重寫RepositoryItem

DevExpress，GridControl如何添加自定義列，重寫RepositoryItem

如何向XtraGrid添加自定義控件

怎樣向XtraGrid中添加自己創建的XtraEditors編輯控件

可以創建 RepositoryItem派生類，並且為其聲明靜態構造方法和注冊方法，如果要在設計器中使用還得給注冊方法添加UserRepositoryItemAttribute屬性標記，還必須重寫RepositoryItem和BaseEdit派生類的EditorTypeName屬性

此用法適用XtraGrid, XtraTreeList, XtraVerticalGrid, XtraBars

注意要添加引用：DevExpress.XtraEditors.v10.2
