Implement map in GrideView

Question

Greeting to all

I work on asp.net web app.

my point is to add map conrol in admin side control panel.

when a admin need to add branch, insert these fields(Branch_name, Phone, Location(text mode), map)

so a question is.

there is alot of solution about map conotol which I able to implemnet it in asp.net side.

so a sensitive point.

 

a map parameters (langitude, and longtiude) is necessary to store it in same column or need to sepearate it.

 And a principle data type to store map vlaue is :(sys.geography) in sql.

 

thanks
