Welcome to ACDS DHX Scheduler

ACDS DHX Scheduler


Alpha Custom Database Solutions, LLC (ACDS) ACDS DHX Scheduler is a custom user defined web component addition for use with Alpha Software's Alpha Anywhere RAD environments (A5). It is only supported for use in A5 browser/mobile based applications (A5 desktop and A5 WCD are not supported). A supported SQL backend is required. There is no support for DBF tables. The component uses a builder, much like native Alpha Five web components, to add a third party scheduler control, DHX's dhtmlxScheduler, a product of Dinamenta, UAB, to your web project. You are responsible for obtaining a license to use the DHX Javascript libraries. A license to use the DHX libraries is not included with the ACDS DHX Scheduler.

The DHX Scheduler control is independently owned, licensed, and maintained by DHX. License terms, pricing, and the DHX documentation can be found on the DHX  web site.

dhtmlxScheduler is a JavaScript event calendar that allows you to add a Google-like scheduler to your web app or website. Intuitive drag-and-drop interface allows the end users to quickly manage events and appointments in different views: Day, Week, Month, Year, Agenda, Timeline, etc. Very lightweight (about 20Kb gzipped), highly customizable, and fast, dhtmlxScheduler provides a quick way to add an Ajax-based event calendar on a web page.

The ACDS DHX Scheduler uses the DHX dhtmlxScheduler Javascript libraries and custom Xbasic code to give the A5 developer a scheduler to use in A5 web projects with full interaction to a SQL backend. Currently tested and supported databases are MySql, Maria DB, Oracle, postgreSQL, Access, and MS SQL Server. Database interaction is accomplished using Alpha's AlphaDAO and portable SQL for seamless support of various databases. Once the necessary SQL table and AlphaDAO connection string is in place a scheduler can be added to a web project with a few clicks of the mouse. No other coding is required for a basic scheduler control. The ACDS DHX Scheduler builder allows for custom HTML to be inserted above and below the scheduler and also provides both pre-initialization and post-initialization Javascript sections that allow the developer to leverage the powerful and feature rich DHX Scheduler API.

SQL Table Requirements

The scheduler requires a sql table. Below are the minimum requirements for the table structure for use in the ACDS DHX Scheduler control.

The tasks table requires four columns. Additional columns, for the various views and options, can be added. Up to five user defined columns, in addition to the required columns can be added for additional data the user defined column inserts and edits will be persisted back to the database. See the section on user defined columns for more detail. An example of the table structures in MySQL is below. Adjust the column types for your database.

/* MySQL format */

CREATE TABLE `tasks` (


`text` varchar(255) NOT NULL,

`start_date` datetime NOT NULL,

`end_date` datetime NOT NULL,



User defined additional columns in the tasks table.

The ACDS DHX Scheduler component builder allows for the use of up to five additional columns in the tasks table. These can be most data types. The data in the columns will be sent to the client and can be used in the scheduler. Changes made to the values of the custom columns are persisted back to the database when their values are changed in the scheduler. See the video on custom task columns for more information.
