update data using DataProcessor


I am using dhtmlgrid DataProcessor in my application update data into Database,

Is there any way to display error text in the GUI, if any checks fail during the update/insert data…

For Example, I am trying to insert a row of data into Database,

before doing insert I am doing few checks based on the Business rules, if any rule fails (If a user is not authorised to save the data), then I want to display an error message like “Jhon Luther is not authorised to insert data.”,

Is there any way to display like this in GUI?, How do I get this message from my server side and where do I catch this message?

Please suggest me in this regard…



Dataprocessor allows to define custom types of responses, which may be used to inform client side code about some kind of error.
