  10. using (schoolEntities6 context = new schoolEntities6())  
  11. {  
  12. List<SecurityModel> newlist = (from c in context.SecurityQuestionDetails  
  13. join sq in context.SecurityQuestions on c.SecQueId equals sq.Id  
  14. where c.UserId == Id  
  15. select new SecurityModel  
  16. {  
  17. Id = c.Id,  
  18. SecQue = sq.SecQue,  
  19. SecQue2 = sq.SecQue2,  
  20. SecQueId = c.SecQueId  
  21. }).ToList();  
  22. ddlQuestion.DataTextField = "SecQue";  
  23. ddlQuestion.DataValueField = "SecQueId";  
  24. ddlQuestion.DataBind();  
  25. ddlQuestion.Items.Insert(0, new System.Web.UI.WebControls.ListItem("Select"));  
  26. }  
  27. }
