Answer / neha

First, you need to bind the label control to the questions
in the database as
Label ques = new Label();
ques.DataBindings.Add("Text", bindsource, "Question");

Similarly, you can bind 4 radio buttons to the 4 options of
the question.
You can provide the button then, clicking on which will
calculate the result and move on to the next question.
For calculation, you need to bind another label's tag
property to the correct answer column in the database, and
can match the strings to calculate whether the user has
entered right answer or not.
Based on that, the score variable can be incremented.
