Google has provided a very reach APIs to use it in our own application. But we need some short of javascript knowledge in order to use it. I dont 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. 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. Features Enables you to draw google map. No javascript knowledge required. Just drag and drop control on your page. Ajax calls to retrieve server side data. Enables you to change pushpin postions on the fly. No need to refresh full map. Enables you to change pushpin icons, positions from asp. Pushpin click and drag event support in asp. Map click event support in asp. Directions support. Allows you to draw route between multiple addresses Polylines and Polygons support. Geocoding support i. Find latitude longitude from specified address and create pushpin on that location. When pushpins are changing positions, automatic boundary reset and zoom support to display all pushpins. Optimized to give you best performance. How to use. In this part of article, I dont want you to explain how I created this control. Instead I want you to start using it. To view documentation for source code visit following article.
