Considering that only I replied to you. Which of your requirement is not fullfild ?
I explained you that store leaves and database months and Employee viz.,than bind an DropDown Months with text as name of month and number as value of the DDL let say for first month text is "January" and value is "1". When one selects the january and enters the employeeId let say 213 than on that basis you can easily fire a select Query like
Select leaveCount from EmployeeLeaves where EmployeeId = 213 [Month] = 1
So what you are not getting ?
Have you created the Table I suggested ?
