I have a form with many dropdown boxes, textboxes, and date selections.
I need to find out at a form level before I close the form whether any of the values in any of the controls in the form changed. This way I know whether or not I need to save the data by running another sub that will get the values and update them to the database.
I am not using datasets or datatables to store/retrieve values. I read values from a sqldatareader and put the values in the appropriate form controls. Then when closing form I loop through all of the controls and save values to database.
Please help, I come accross this all the time and need an answer very quickly.
