In this article I’m
going to explain how to bind data to GridView in ASP.NET using C#.
What
is Gridview ?
Gridview control
displays
the values of a data source in a table where each column represents a field and
each row represents a record. The GridView control enables you to select,
sort, and edit these items.
Here I’ll show you how to bind data to
Gridview from
data source.
I have used
Northwind database to bind Product details to GridView. Here you can
download Northwind database
