I have a requirment when print the form.
If user choose the Print Button ,after printing, some table will be updated.
If user choose the Cancle Button, needn't updated any table.
If user choose the Preview Button, and then user cancle the preview, also needn't update any table, if user print the form , update table.
so, my problem is when user choose the Preview Button and cancle it, how to do it? 3ks!
