Update and delete a record

Question

Hi all
I have a requirement in oracle forms 6i
I have a data block which is tabular
there are 5 columns
1 column is display only and other 4 are normal text fields where we can insert update and delete those records
My requirement is when a user updates a record an alert must fire and the alert should ask whether the user wants to update that particular record
if the user presses yes then the record should be updated else the record should show as it was previously shown
Similarly in case of delete an alert should fire where it should be asked for confirmation if the user presses yes then the record should be deleted from the data base
else the record should be again visible on the form as earlier
also my 3rd requirement is that
i have a item field which is normal text and the display only field is the description
when entering a new record when i enter the item field and press tab or navigate out of the item field then the description of the item should be pouplated into the decsription read only field
Please help me in the above 3 cases
I am new to forms
I am using a friends ID which has many posts
Thanks in advance

1)
your first requirement i'd do in the PRE-UPDATE trigger of the block:
DECLARE
    v_alert_button NUMBER;
BEGIN
    v_alert_button := SHOW_ALERT('your_alert'); -- "Do you want to update?"
    IF v_alert_button = ALERT_BUTTON1 -- assuming "No"
    THEN
        -- reset value:
        :YOUR_BLOCK.YOUR_ITEM1 := GET_ITEM_PROPERTY('YOUR_BLOCK.YOUR_ITEM1', DATABASE_VALUE);
        -- optionally set item to valid if you don't want validations to fire:
        SET_ITEM_PROPERTY('YOUR_BLOCK.YOUR_ITEM1', ITEM_IS_VALID, PROPERTY_TRUE);
        -- do this for every item:
        :YOUR_BLOCK.YOUR_ITEM2 := GET_ITEM_PROPERTY('YOUR_BLOCK.YOUR_ITEM2', DATABASE_VALUE);
        -- finally reset record status:
        SET_RECORD_STATUS(:SYSTEM.CURSOR_RECORD, STATUS, QUERY_STATUS);
        -- interrupt PRE-UPATE trigger:
        RAISE FORM_TRIGGER_FAILURE;
    END IF;
END;(not tested, please try for youself)
2)
raise the alert in PRE-DELETE trigger.
3)
you can do this within the WHEN-VALIDATE-ITEM trigger or a List-of-value (LOV) that returns the description values.
