私が進めた方法は次のとおりです。
テーブル名：tbltt
1.ソースコードからテーブルを追加しました
2.csページに行と列を作成しました
3.データは実行時にバインドされます
4.テーブル値を保存したいので、その中にコントロールを見つけたい（各行と列にドロップダウンがあります）
以下の表

string[] p = { "flag", "campusid", "ttid" };
string[] v = { "3", campusID.ToString(), ddlTimetable.SelectedValue };

コントロール「ddlsubjects」を動的に取得するメソッドが必要です。つまり、その値を取得したいのです。これを取得するための適切な方法を教えてください。助けていただければ幸いです。ありがとう。
