In the App I am writing for my wife, She wants to be able to change the number of servings in a recipe and have the program automatically adjust the amounts of the various ingredients she needs.

The amount of each ingredient in the original recipe is stored in a column of a data table that is then loaded into a data grid view for display.

So when the user changes the number of servings, can I somehow access the data stored in the data table and modify it before I reload the datagridview?
