我使用ASP.NET C# 開發一個網頁

我想運用TreeView方式提供使用者可編輯自己的Sidebar順序
所以我有建立一張資料表專門記錄登入者ID 與與該名使用者之Sidebar階層關係
目前遇到2個問題

1.如遇無限階層該如何寫

例如:
名稱父階ID ID
頁面1 0 1
頁面2 1 2
頁面3 1 3
頁面4 3 4
頁面5 1 5
頁面6 0 6
頁面7 6 7
頁面8 0 8

像這樣而我參考了 https://demos.shieldui.com/web/treeview/drag-and-drop
進行練習發現我不知道如何撰寫一個可不限總共有幾階的程式想請教各位大大我該如何撰寫

目前我的寫法是先找父階為0 再去用他的ID找父階是他的ID的但這樣變成是假如有3階我就要寫3個foreach 4階就4個....
能有有大大可以教我該如何寫呢?

2.使用者拖曳完成後我該如何取得使用者修改後階層，因為要回存至資料庫
