Along with incremental bug fixes and continued improvements to the Alpha 2 release, the Beta 1 build also includes:

WebList Grouping

The cWebList class now supports grouping of data. When enabled, the user can configure the groups via the context menu on the header of the list.

Web Grid Layout

The grid layout is a new layout system now available for web applications. It provides more control over the vertical positioning of your controls. It is based on the CSS grid layout.

Better Studio Icons for High DPI Screens

The icons now contain larger sizes for high DPI screens. This especially shows when running the studio at 200% or higher.

The What’s New in DataFlex 2023 – Beta 1 section of the help details all the latest changes in the pre-release build.

Along with incremental bug fixes and continued improvements to the Alpha 1 release, the Alpha 2 build also includes:

CodeSense in SQL Queries:

The Studio will now help write SQL queries by providing CodeSense on your SQL statements when using @SQL strings in the language or when using the Query Tester.

Aligned multiline strings

When embedding foreign code like SQL, JavaScript or HTML into DataFlex code, you can now use a new style of multiline strings that allows better alignment with the rest of your code without adding additional whitespace.

Customizable context menu for WebLists

The context menu available in the header of cWebLists and cWebGrids can now be customized.

Improved Query Tester

Besides being extended with CodeSense, the Query Tester has been updated with the ability to show multiple result sets and can execute partial SQL statements by selecting text before executing.

DataFlex 2023 Alpha 2 includes many other features and improvements. See all in the online documentation.

To get started with DataFlex 2023: 

DataFlex 2023 extends the DataFlex ecosystem by providing exciting new ways to build windows user interfaces and much more natural ways to execute SQL statements.


DataFlex 2023 introduces FlexTron, which brings Web views and controls into Windows applications, allowing a more modern look and feel or just adding Web features to more mature Windows applications. You can use a single Web control or build entire applications. 

New Embedded SQL API 

  • DataFlex 2023 comes with a new way to work directly with SQL statements. A new engine for executing statements is built into the runtime that puts result sets directly into native DataFlex types. This means that your results can now go directly into structs, multidimensional arrays and variants with the proper type conversions being done automatically. Parameterized queries now support named parameters and only a single class / object is needed for executing queries. 
  • Studio support for working with SQL statements is improved by adding syntax highlighting, code sense and a query test tool for SQL statements.
