The most demanding usage of forms is to display data from the database and to post data in the database. This section explains about how to save form data in the database.
The following diagram illustrates the form data submission flow:
Creating Creating JS listener class for the Form
When a form or form item action is triggered by the handlers, Canvas executes its corresponding actions registered with the global form listener key CFLR. This provides the freedom to the developer to write their action logic anywhere within their application.

cbx.ns("namespace id");
listenerClass = Class(cbx.Observable,
{
constructor:function(config)
{ },
//Inside the following function, listeners related to all form components are registered.
registerHandlers:function()
{
//Form Listener
//this.fm.registerHandler('cbxpremodelload', function (fm, record){
{ });
//Form Item Listener
// this.fm.registerHandler("cbxdateclear", "<FORM_DATEFIELD_ID>", function (fm, event,
fieldName, value)
{ });
}
});
CFLR.registerListener("FORM_ID", listenerClass);
//Form Container Action button listener

CABR.registerHandler('ACTION_BUTTON_ID','CONTAINER_ID', function (config){
