Iam creating a datatable as

        DataTable dtVndDtl = new DataTable();            
        dtVndDtl.Columns.Add("prvn_Id");
        dtVndDtl.Columns.Add("vend_Name");

Answer 1

The extra row that is getting added at the end will not get added in database,it is getting added in gridview. If you don't want that extra empty row to appear then you can set DataGridView.AllowUserToAddRows property to false. That extra row will not appear in gridView.

Answer 2

I wouldn't really bother with finding out why this happens :). Why don't you just remove the last row manually before adding to database?

Other option is to implement RowCreated event handler and see when exactly this happens so you can do something about it.
