    <p>I am a new ASP.NET developer and trying to develop two dynamic tables where the user can add a new row directly in the first table, when he finished adding it, he will be able to select it to open the second table underneath the first table. I have a problem now in selecting on the rows in the first table in order to show the second table. <strong>So how to get it?</strong> </p> <p>FYI, I have the following database design:</p> <pre><code>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 </code></pre> <p>In addition, the first table will be for inserting the questions and the second table will be for inserting the answers. So how I can select a question to show the second table and being able to insert the answers for that question.</p> <p>ASP.NET Code:</p> <pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"&gt;

    2. COis it possible to do what I want and explained above very easily with the GridView? Also, it will be a waste of time now to repeat what I did from zero. What do you think?

    3. COYes I think GridView is the best option. But I haven't used asp:Table before to work with data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
