我是一名新的ASP.NET開發人員,我正在嘗試開發一個簡單的測驗引擎,它將允許系統管理員使用兩個ListView創建測驗。第一個用於插入測驗題目和說明的ListView,第二個ListView用於插入問題,答案(不同數量的答案),正確答案,答案解釋,問題順序。如何開發這個依賴於另一個ListView的ListView?
我有以下的數據庫設計:
Quiz Table: QuizID, Title, Description
Question Table: QuestionID, Question, QuestionOrder, AnswerExplanation
QuestionImage Table: ID, QuestionID, URL
Answer Table: AnswerID, Answer
QuizContent Table: ID, QuizID, QuestionID, AnswerID
,我已經讓我感到困惑與數據綁定第二ListView中的要求:
- 每次測驗有不同數量的問題,並每個問題有 不同數量的可能答案。例如,在其中一個測驗中,我有兩個問題。在第一個問題中,我有四個可能的答案,第二個問題是真或假問題。
- 有些問題可能會有一些圖像。
此ListView應該支持CRUDE操作。 那麼該怎麼做?
我的ASP.NET代碼爲先的ListView:
<asp:ListView ID="ListView1" runat="server" DataKeyNames="QuizID"
DataSourceID="SqlDataSource1" InsertItemPosition="LastItem" >

我現在的問題是我怎麼可以讓管理員能夠按照他的意願輸入不同數量的答案。 任何人都可以幫助我嗎?
這根本不是很清楚。您需要澄清要求。我甚至不會冒險解決問題,因爲如果你有一點點關閉,人們會在短時間內讓你失望。這聽起來像你想要使用第一個listview的選定值在第二個的where子句中使用。這似乎很簡單。我在正確的軌道上嗎? – GrayFox374 2012-07-17 05:33:16
感謝您的反饋。你能看看我更新的問題嗎? – 2012-07-17 06:32:35
當然。我要睡覺,並在早上看看它。 – GrayFox374 2012-07-17 06:39:07
