    Create a History table

    Hi,

    I have a datagridview (DgvPracExcl) which at runtime allows a user to update the records to a table in the database.

    Now, I want to save a history prior to the update. Therefore, create a history table..

    Any ideas...

    Thanks

    my first idea is create handle keydown on datagridview.
    on first keydown event store old value in memory , on enter/end edition compare with actual value, if different then log in your history...
    This way you can log all rows or selected cells

    Am I right?

    Trap the ENTER key, the ARROW KEYS, and most importantly handle the BACKSPACE correctly. There are many samples. Cell Enter and Leave might or might not process the data before leaving
