How pass Update datarow from Gridview to Business Object

[Bobby Edward]

I have a business object method called UpdateCategory that calls the Update
command of a xsd dataset I created.

The Update has 5 overloads: DataTable, DataSet, DataRow, DataRows(), Actual
Fields

I am using a Gridview to call this object method. Which overload do you
suggest I use and how do I pass it from the Gridview to the business object
method?

I would prefer to stay away from using the Actual Fields (for the Insert and
Update) because the table could have many fields.

Any ideas?

Thanks!
