get change textbox value only
Hi
I have a senario where I am try to get values from 100 records and each record has 10 columns (10 values).
form look like grid layout with 10 columns and 100 rows.
Problem is when values are retrived and displayed in the form most of them are null. and user will update the values from the form.
Everytime when user clicks on update 100 records will be getting updated. but let say user changes only 2 records(rows) and clicks on update it will send 100 records(1000 values to database) and number of changes 2 records(20 values).
This will make process slow.
My question is there anyway I can save only the changed values and update the records insted of sending all values.
capture changes and update database.
Thanks

Change the backend logic .i.e. once the user changes(updates) the fields in front-end, in the database, update only those fields which were Changed in front-end. Those fields which were not changed , should not be updated in database.

you can use a hidden form field on every record and then use java script to update this value when user changes anything on the record.
at the back end you can check this hidden field to determine which records needs updation in the database...

true, just like setting a flag for the field!
:-) I have used this trick more than I can care to remember.
