View 7 RepliesI have a webservice that a developer can use to create a user account, apart of the create user account form, it requires an input of the user's "Postal Address"The Postal address has "Country State Id"Normally, I would provide a list for everything else, but when it comes to country state list it contains thousands and thousands of states/regions and its too much to list in a API specification document.
So my question is, 1) do you create a web service for the developer to retrieve the country state id?
or 2) provide the developer with a database file, with the list of country state id?

View 5 RepliesI want populate the dropdownlist1 with Country and dropdownlist2 with City of that Country from web
Is there a place on web where we can get a list of countries and cities handy, and then populate into our dropdownlists in ASP.net page.
I have a cascading dropdownlist. The first drop down is for Departments and is databound on PageLoad from the database. The user then selects a department and the second dropdown is populated with the appropriate sub departments via JQuery/JSON which calls an httphandler. The problem is as follows: I select a department and the subdepartments are filled.
I finish what I'm doing on that screen and everything is fine. But then if I go to a different screen and add an additional subdepartment then come back to original screen, the new sub department won't appear in the cascading dropdown. I have to close the browser and restart the session in order for any new sub departments to appear even though they are in the database. I put a breakpoint in the httphandler and noticed that it is only called once per session per each department in the first dropdown. I don't know why this is happening. I want it to call the httphander EVERY time the index of the department dropdown is changed.
