Cascading 2 DDLs with sql tables in MVC without using entity

Question

A newbie to programming, so pls bare with me... 

 

Have 2 tables in sql:

tbl_Dept : DeptID, DeptName

tbl_Emp :  EmpID, EmpName, DeptID (Dept ID is foreign key)

 

I am trying to create two DDLs where in when I select DeptName from DDL1, it should show me EmpNames of the selected Dept in DDL2.  How do I do this in MVC, preferably without entity framework? 

 

I did it in asp.net, but not sure how to do this in MVC?

 

any help is appreciated, thanks!
