>I am not using datasets. Am loading data into web page controls on first pass and using viewstate between posts. I have a datagrid that I've added a checkbox that is bound to a bool value - the datagrid is loaded with a datareader. The only actionable columns are the checkbox and a link column. I want to use a button on the form to update the database if the checkbox.checked property has changed (checked/unchecked).

Dean,
You can check the control's ViewState property to see the value that was saved during the postback.
