VCL Controls - 2019 Roadmap

VCL Team Blog
18 February 2019

Based on survey results and Support Center feedback, we’ve finalized our 2019 Roadmap. We want to thank you for your continued support and for your insightful comments.

Important Note on Survey Results

The survey's main question was about our commitment to the FMX platform. In the end, 36.6% of respondents chose FMX Grid over additional capabilities for VCL products. On the one hand, we understand that this does not amount to a majority of votes. On the other hand, this result demonstrates that a substantial part of our customer base is interested in FireMonkey. After careful consideration, we decided that we will proceed with FMX Grid development and will implement 6 of the most popular VCL product enhancements listed on our survey. Percentages below are given based on the number of people who chose additional VCL capabilities over FMX Grid.

  • ExpressQuantumGrid - Improved Performance (84.07%)
  • ExpressQuantumGrid, TreeList & Vertical Grid - New Expression Editor and Calculated Columns (74.34%)
  • ExpressQuantumGrid - Entity Model Framework-based View (53.98%)
  • ExpressQuantumGrid & TreeList - Scrollbar Annotations (53.1%)
  • ExpressNavBar - Hamburger View (52.65%)
  • ExpressScheduler - Improved Performance (calculations/drawing) (39.82%)

You'll find all these features in the complete list below, combined with the other enhancements we plan to implement in 2019.

If you have any issues with the roadmap or questions about implementation, feel free to email us at - we will be happy to follow up.

Entity Mapping Framework-based View (v19.2)

This new view will leverage Entity Mapping Framework's superior data management performance. You will be able to handle large datasets as you would do in Server Mode, but without certain restrictions associated with it. For example, the new view will support data modification and Master-Detail layouts.

Improved Customization Options (v19.2)
We will re-design the column/band customization dialog. The design hasn't been finalized yet and we'll use the following UI metaphors as the starting point.

Immediate Post Option (v19.1)
This option makes most sense for editors where free text input is not available or secondary. If you use a check box or a combo box, enable this option to save the value as soon as a user switches the state or selects a different item. If the option is turned off, the value will be saved when the editor loses focus or when the user presses Enter.

We will also deliver a number of minor requests referenced by the following support tickets:
