Initializing ColdFusion Connector

To use the functionality of DHTMLX Connector, first you should initialize it.

Generally, both client- and server-sides are concerned in it.

Client side

If you need just load data from database (with or without data preprocessing)

1) Specify connector file in the load method of a component.

//index.html myGrid = new dhtmlXGridObject("someContainer");// initializes grid ... mygrid.load("myconnector.cfm");

If you need to perform any update operations

1) Specify connector file in the load method of a component.

2) Initialize dhtmlxDataProcessor on the client side (read more about it here).

//index.html myGrid = new dhtmlXGridObject("someContainer");// initializes grid ... myGrid.load("my_connector.php"); myDP = new dataProcessor("myconnector.cfm");// initializes dhtmlxDataProcessor myDP.init(myGrid);

Samples Client-Side Initialization

Server side

Preparations:

1. Create datasource in CF Admin (further, we will use “datasource” variable for this).
2. Put connectors into the folder that can be achieved by your custom cf templates.

Main steps:

1. Include the appropriate connector file into the page.
2. Instantiate the connector object. Linking variable is a mandatory parameter in all constructors. The second parameter(database type) is optional. By default it's “MySQL”.
3. The last step is data configuration.

<cfinclude template="../config.cfm">// connector file <cfset grid = createObject("component","dhtmlxConnectors.GridConnector").init( "#datasource#","MySQL")> <cfset grid.render_table("mytable","item_id","item_nm,item_cd")>
