hello,

i hope sates and districts both you are fetching from database tables.

if yes then given solution will work

state table 

state_id statename
1           abc
2           def


districts table

districts_id  districts    state_id/Statename
1                 xyz                 1
2                hhh                 1
3                 kkkk                2


you can get districts  by following query


select districts from tbl_districts where statename=@statename

when you store state name in citytable


or 
select districts from tbl_districts where state_id =(select state_id from tbl_state where statename=@statename)


you need to pass statename to @statename from first ddl.
