From time to time it's great fun to stray off the beaten .NET path to venture into other developer's hemispheres. This time I paid a visit to the great crowd at the EMEA PUG Challenge in Noordwijk/Netherlands to dig into the Progress community.
For you as an enterprise application developer, logging is probably one of the essential features of your app. It enables you to trace and see what the user did just before the app went blank, and see if the typical user answer "I haven't done anything" proves right or wrong. To support you in this task, logging was built into List & Label from the very start.
Until version 22, there was a number of restrictions for web based projects. As the Web Designer is a single project file designer, all the glory that comes with multiple project files like project templates, table of contents and index and – most prominently – drilldown support were not available as they couldn't be designed.
Quite a while ago we introduced a full screen presentation mode which allows you a quick presentation of your reports. Why fire up PowerPoint (or any other presentation software) when you just need to present a couple of charts and tables? This way, your presentations are lightweight and always up to date, as you or your end-users can re-create them just in time.
This is one of those "whaaaaat, that didn't work before?" features. No, it didn't. Until version 22, you were only able to sort bar charts with string labels ascending or descending. Alphabetically. Numerics and dates are treated differently, but for strings you only could get A-Z, Z-A or unordered, i.e. in the order the database supplies the data.
With Treemap charts you can visualize hierarchical data by using nested rectangles in the upcoming version 22 of our List & Label reporting tool. The area of each rectangle is proportional to its value, while the sum of all rectangle areas fills up the whole chart area.
Version 22 of List & Label will introduce a new WPF wrapper control for the existing WinForms PreviewControl. While it uses a WindowsFormsHost at the core, the wrapper is a drag & drop replacement for the existing WPF preview control which will continue to be supported.
As we swiftly proceed through the development process of List & Label 22, we found a slot to add one more feature to the crosstab. Starting in version 19, we've added a lot of interactivity to the preview, including a feature called "Expandable Regions" for the report container. It allows to expand sub tables by just a click. For LL22, we've now extended this feature to the crosstab.
This is one of the major UI visible changes in LL22. All objects have their distinct set of properties which is displayed in the property window. Depending on the complexity and flexibility of the object, the list of properties is quite long where most of the time you probably don't need 50% of them. Enter the new Property Favorites.
The IDataProvider interface for .NET has enabled many features that are not available for all of the other platforms so far. Most importantly, it brings multiple report containers and nested tables. For C++, we've included a sample in LL21. This is sadly missing in Delphi. In addition, the current Delphi data-binding engine still works against the BDE, a technology that has been deprecated quite a while ago by Embarcadero.
