Google has provided a very reach Google Maps API to use it in our own application. But we need some short of javascript knowledge in order to use it. I don't know about others, but for me it was a little difficult to use javascript along with google apis in ASP.Net pages, specifically if you want to use server side functions to draw google map dynamically. For example, in my case I wanted to pull latitude longitude information from a SQL Server database and then use them to insert pushpins on google map. If you are familiar with Ajax framework, you know the answer. You will have to call asp.net server side function from javascript and use retrieved data to draw a google map. How simple is that? :). Atleast not for me. So I have decided to write a user control which can take care of javascript part and allows me to concentrate on serverside functions.
