I'm trying to use a Gridview to add data to a dataset Datatable starting with a blank Gridview. I know the columns for it and they fixed. What I would like to do is be able to have a blank row in the Gridview show up on page load and then be able add N number of rows. In the end, i'd like to do some calculations on the data and then submit it to a DB. but thats later on down the road. My first step is to show a blank GridView and be able to add to it. Any ideas?
