How can I export a GridView.DataSource to a datatable or dataset?

Question

How can I export GridView.DataSource to datatable or dataset?

Answer 1

Personally I would go with:

DataTable tbl = Gridview1.DataSource as DataTable;

This would allow you to test for null as this results in either DataTable object or null. Casting it as a DataTable using (DataTable)Gridview1.DataSource would cause a crashing error in case the DataSource is actually a DataSet or even some kind of collection.
