Hi i have  Three drop down  and i am using cascading dropdown

this works fine.

But it call GetCoutry and GetCity Method simultaneously and execute line by line from one method. eg one line from GetCountry then one line from Get city and repeate the process.

Ideally it shold call GetCountry then GetState then GetCity.

Please help me out regarding this problem.

I have tried your code and it seems things r alright there. It looks like its issue with you web service method implementation, can you share ur web service code?
