for evry quesion there are so many checkbox i have to select one of them which one is correct, then save that thing in database. now the problem is that for each question checkbox i only have one property(same name). so as soon as i select any checkbox for second question the selected checkbox of 1st question gets deselected and that is obvious. and this question No are dynamic so there can be 10 question or anything. so can anyone suggest me how to solve this problem. and the thing is that i can not put all question in different it must be same page.Is it like i have to dynamically generate the property?
