I have created a DataSet from a Database. I perform a LINQ query and get a subset of the data I am interested in and that data is in an array, the resulting array is bound to a grid. If I make a change to one of the cells in the grid which will update the array list what do I need to do to get changes back into the DataSet? I think once the changes are back in the DataSet I can get the changes back into the database. If some one could point me to some code examples that would be most helpful. Thanks.
