如何开发这个依赖于另一个ListView的ListView？

我是一名新的ASP.NET开发人员，我正在尝试开发一个简单的测验引擎，允许系统管理员使用两个ListView创建测验。 第一个ListView用于插入测验标题和描述，第二个ListView用于插入问题，答案（答案数量不同），正确答案，答案解释，问题顺序。

我有以下数据库设计：

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 

我的要求让我对第二个ListView与数据的绑定感到困惑：

1. 每个测验都有不同数量的问题，每个问题都有不同数量的可能答案。 例如，在其中一个测验中，我有两个问题。 在第一个问题中，我有四个可能的答案，第二个问题是真或假的问题。
2. 一些问题可能有一些图像。

此ListView应支持CRUDE操作。 那怎么做？

我的第一个ListView的ASP.NET代码：

         <asp:TextBox ID="TitleTextBox" runat="server" Text='' />   <asp:TextBox ID="DescriptionTextBox" runat="server" Text='' />     
 
 
 No data was returned.
 
 
        <%--  --%>  <asp:TextBox ID="TitleTextBox" runat="server" Text='' />   <asp:TextBox ID="DescriptionTextBox" runat="server" Text='' />          <%----%>  <%-- <asp:Label ID="QuizIDLabel" runat="server" Text='' /> --%>  <asp:Label ID="TitleLabel" runat="server" Text='' />   <asp:Label ID="DescriptionLabel" runat="server" Text='' />

我的第二个ListView的代码：

 
        <%-- <asp:Label ID="QuestionIDLabel1" runat="server" Text='' /> --%>  <asp:TextBox ID="QuestionTextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="Answer1TextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="CorrectAnswerTextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="AnswerExplanationTextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="QuestionOrderTextBox" runat="server" Text='' CssClass="textbox" />     
 
 
 No data was returned.
 
 
        <%--  --%>  <asp:TextBox ID="QuestionTextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="AnswerTextBox" runat="server" Text='' CssClass="textbox" />    <asp:TextBox ID="CorrectAnswerTextBox" runat="server" Text='' CssClass="textbox"/>   <asp:TextBox ID="AnswerExplanationTextBox" runat="server" Text='' CssClass="textbox" />   <asp:TextBox ID="QuestionOrderTextBox" runat="server" Text='' CssClass="textbox" />       Please enter the letter of the correct answer A, B, C, D.          <asp:Label ID="QuestionLabel" runat="server" Text='' />   <asp:Label ID="Answer1Label" runat="server" Text='' />   <asp:Label ID="CorrectAnswerLabel" runat="server" Text='' />   <asp:Label ID="AnswerExplanationLabel" runat="server" Text='' />   <asp:Label ID="QuestionOrderLabel" runat="server" Text='' />
