What is the alternate way to replace Dataset to bind data in Datagrid.

you can also use data reader to populate your grid with the values in the database

I know we use Dataset component to bind the data into datagrid,but if we don't use the Dataset what is the alternate way or what is the class which Datagrid supoorts to bind data. i.e. if we want to write a class to bind data in Datagrid then which class should we use.
