In which language you want this in Windows Forms? Inspite of that i think you populate the combox2 data at the form loading time or employee selection time. Actually on form load time combox2 will need to be totally empty no data source need to defined at that time. When you select the leave head from combox box1 then on change event of that combox1 you need to provide data source of combobox 2. Hope this will help you.

Yes. I have windows form, And I using C# language. My problem is, I have Leave table and Payroll table on database. And Leave table have Id, Date, EmployeeId, LeaveCatagory, leaveDay attributes. Payroll table have id, date, EmployeeId, BasicSalary, NetSalary Attributes. I have 3 combo box in my payroll interface. When I select EployeeId, The LeaveCatagory and Days Combo box should be load automatically depends on EmployeeId. But problem is there, when I select EmployeeId the All days leave is showing the day combo box. I don't need this, I need to select EmployeeId, then the LeaveCatagory combo box will show this employees LeaveCatagory that leave was formal or casual, then the combo box show the just selected values item on days of EmployeeId. That's All.
