I have found useful tool here (All US States and counties on combo-box) its using Java script API 1.3 version.
I have downloaded the tool and trying use but its gives an store error (using version 3.1) but when I change the version to 2.8 its working fine..so how do I implement it for 3.1 version.
Is there any document or instructions ?? (Because Esri mentions that only upgrade the version no. ex. 2.8 to 3.1 )..
Software that I am using is ArcGIS Java Script API ver 3.0 & ArcGIS Server 10.1,Desktop 10.1
