Hi Dipu, You can check in two ways: bool isCorrect = False; foreach (ListItem item in Question1.Items) { if (item.Selected) { if(item.Value == "Admin Value" { isCorrect = True; } break; } } // Check whether answer is correct or not?? if(isCorrect) { Correct } else { Wrong } Using LinQ List selectedValues = Question1.Items.Cast () .Where(li => li.Selected && li.Value == "Admin Value") .Select(li => li.Value) .ToList(); if(selectedValues.Count >= 1) { Correct } else { Wrong }

You can start your project in Multiple ways. Some of the option I am sharing here: Option 1: ======== 1) Have a flat file (Binary format) of Questions and correct answers in it. You can have question bank say 1000 Questions and May display only 20 to the user. 2) In the Question form you randomly pick a question from the file and display it. (When you load a question, you load the answer as well. But, in the form you only display the question) 3) Based on the answer given by user (By selecting the options), you increase his score by comparing his answer with one loaded from the binary file. Option 2: ========= Do the same stuff above, but in-place of flat file, use any database of your choice :)
