Grid view with binding of dropdownlist in the user control?

Thank you @Munesh Sharma . but this is not the solution what a looking for. actually i want to bind the dropdownlist into gridview in a user control . But i also want to bind this dropdownlist with different data source according to the page required .I mean that if i use this user control in a page name like "financial.aspx", at that time the dropdownlist will bind with "financialcriteria" or if i use it in "salary.aspx" it will bind with "salarycriteria" ,actually i want to bind the dropdownlist dynamically from different .aspx page.
