How to update a database table column using ajax call back process. I have a an interactive grid on a table A and when records in table A are updated the process should get user confirmation and update table B if user confirms by pressing ok. I have created a customer button for Update. I have a hidden data item which is incremented after the grid is saved. I have a dynamic action created on change of the hidden data item to execute javascript and call the ajax callback process. It works fine and give the confirmation message. However, when user presess Ok, i am not able to update the database table B Any suggestion will help.   Thanks, Vina
