C#

        String a = "Select que,op1,op2,op3,op4,answer from test";
        SqlDataAdapter objcmd = new SqlDataAdapter(a, ob);
        DataSet ds = new DataSet();

So other than in your button click event, you are not querying the database for the next question and you do not have a WHERE clause to select a question, what is it that your question is?

Solution 1

As the code shows,

On the Page_Load it loads the first question as x=0 and on the Button1_Click it shows the second question as x becomes 1. Based on the provided code it is doing as you wrote and said.

I assume by saying "it shows only two questions" you might want to display the question in sequence based on the button click. If that's the case, you might try,

You might retrieved each question individually based on the current question no which you need to store somewhere, read more about ASP.NET State Management Overview[^]. There might be performance issue for retrieving one question at a time.

Hope it helps :)

I think he/she must use hidden field instead of int x

Mohammad A Rahman 6-May-12 6:46am

I didn't give the OP any solution because there wasn't any clear question, what I did I explain to OP, Op's own code. Come to your point, might be but that is a design issue :)

Thanks anyway.

Ok Mohammad, so you've accepted that your answer was not a solution and it was just a explanation (comment). I think you got the wrong place. (For comment click on "Have a Question or Comment?" and for goving a solution click on "Add a solution")

Mohammad A Rahman 6-May-12 8:11am

Ok Shahin, so I have accepted that my answer was not a solution and it was just a explanation(comment). Now I have modified it to make it a solution or suggestion which is not a explanation(comment). I think I got the wrong place before as now I modified everything should be sweet :).
Thanks for the guidelines about the Commenting and posting the answer :)
