I'm populating my data grid in aspx page by binding List<Exams> from a web service response. But I wanted the users to able to submit selected rows for storing in the table and others may have already been submitted. How do I conditionally populate the grid so users can only submit a row that haven't been already submitted? I mean, populate all of the rows on the grid regardless and differentiate the already submitted one from the others?
Can somebody advice me please.
