Question

My checkboxlist contains 3 items A,B,C.
If user checks A which is what i want then user will obtain 2 marks
else user obtains 0 marks

My problem is that whenever user checks more than 3 item, user is still able obtain 2 marks, whereas by rights user should obtain zero marks because user checked A,B,C?

so how to make that if user has checked more than 1 box in checkboxlist then user will obtain 0 marks

example

if(A==A){
    //user obtain 2 marks
}else{
    //user obtain 0 marks
}

dtr = cmd.ExecuteReader();

if (dtr.Read())
{
    if (dtr["Answer"].ToString() == CheckBoxList1.Text.ToString())
    {
        Label2.Text = "2 marks";
    }
    else
    {
        Label2.Text = "0 marks";
    }
}
else
{
    Response.Write("db not read");
}

dtr.Close();

Answer 1

well, i figured out the answer, thanks for help=) every checked the numSelected will increase by 1,once numSelected more then 2,user will get 0marks

int numSelected = 0;

foreach (ListItem li in CheckBoxList1.Items)
{
    if (li.Selected)
    {
        numSelected = numSelected + 1;
    }
}

Response.Write("Total Number Of CheckBoxes Selected:");

Response.Write(numSelected);
