I am a new ASP.NET developer and I have to create a quiz engine application. I am using three LiveView controls to show:
1. quiz information
2. question information (based on the selected quiz on the first ListView)
3. answers information (based on the selected question on the second ListView)
I have the following database design:
QuizContent Table: ID, QuizID, QuestionID, AnswerID, isCorrect
Quiz Table: QuizID, Title, Description, isSent
Question Table: QuestionID, Question, QuestionOrder, AnswerExplanation
Answers Table: AnswerID, Answer
What I want now is the following: when the user (who is the Admin) comes to the Quiz Engine Page, he should only see the first ListView which is mainly about the Quiz Information. And when he selects one of the quizzes, the second ListView will be displayed with the Question information of that selected quiz. And when he selects one of the questions, the third ListView will be displayed with the answers information of that selected question.
So how to do that?
I know I should not post too much code or information, but I have to do it to make it clear:

NOTE:
I don’t have any code-behind. And again the problem is as following: when I run the code, I will see the three ListView controls. It should show only one of them. And when the user selects one of the rows, the second ListView will be displayed and so on for the third ListView.
UPDATE:
I tried the following way but it did not work with me:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ListView1.SelectedIndex = -1;
}
}
protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
{
ListView2.DataBind();
}
Add the DataKey Like this
And make sure to get the ID in the SQLDataSource
then in the Itemcommand try this :
here is your ID now you can make the second listview visible and use this ID to Fill the second Listview
Hope I Helped
