I have a web application that shows data from a table in a grid. It uses a Select * query to fill a datatable. Then I populate my grid using the datatable. I want a user to be able to edit/change the data in the grid. After editing the data I want to be able to retrieve just the rows of data from the grid that the user made changes to. The changed rows will then fill a seperate Datatable which I need for a specific function.
How can this been accompished ?
