I am very happy for the prompt attention given on the previous question
 
But i just want to understand some points clearly
 
I have read the API of DTHMLxGrid, specially on dhtmlxConnector and said this in nutshell:
 
- dhtmlxConnector is a set of PHP classes which helps to simplify server side operations related to dhtmlx library components (dhtmlxGrid/TreeGrid, dhtmlxTree, dhtmlxCombo).
- There are 2 ways to Load and Edit Data: (Single Table Operations) and (Join tables and complex queries operations)
 
there are 2 methods:
 * render_table
 * render_sql
 
The first method is all you need to make connector implement select, insert, update and delete operations, and do not require any additional code.
 
The second Method, i need to use events handlers to define update/insert/delete statements accordingly.
 
Am i all right?

In most cases it’s correct.



If you, for example, generate grid from several tables, you need to define specific action by sql->attach method:
