Scripting Support in Functions

List & Label has a very powerful formula language. Most manipulations one could think of are possible out of the box or can be realized by using a user defined designer function. However, the latter requires you as a developer to think of the need before deploying your application. In LL21, we'll introduce a new feature that allows to use C# or scripting host languages like VBScript directly in the function wizard.

New and Overhauled Data Providers

The ObjectDataProvider is one of the key providers we ship with LL. It binds to generic lists just as well as to EntityFramework or other Object Relational Mapper data. It is also the final fallback for all datasources that cannot be handled by one of the other providers. In LL21, the provider got a couple of new features for the .NET 4.0 assembly.

Consolidating Syntax Errors in One Tool Window

One of the most frequently requested features via our feedback portal and a feature we were thinking of for quite a while. Before, if a project contained syntax errors (e.g. it had typos or you renamed a field in the data source) you got a massive dialog containing the source of the error, however no easy way to fix it from there. Additionally, this dialog popped up for each and every error so most of you will probably just have clicked the "OK for all" button and started to investigate manually. This was a time consuming, tedious task which often ended up in opening and closing the designer until all errors were fixed.

New Web Designer

Until version 21, we used browser specific plug-ins or ActiveX controls in order to display the Designer right in the browser. However, browser vendors are more and more restrictive and begin to ban plugins from their browsers altogether. Thus, it was time for a new technology.

End User Friendly Conditional Formatting

This is one of the major new features of LL21. Conditional Formatting is needed whenever you want to change properties depending on data, e.g. something like "red font if value is negative" or "highlight the background if value is greater than threshold". This allows to read a report at a glance and quickly get an overview of what areas of your data require a second look.

Lightning Fast Aggregations for .NET

Aggregation within reports is a hot topic. While it is very convenient to just aggregate what you see it can become very expensive if huge amounts of data are involved. Think of sales statistics for your products – you don't really want to iterate through all order details in order to just get the total sales for your article. This is a task databases are optimized for.

Support for Nested Tables

One of the few requests that kept coming in was "Can we have the detail data in a column of the master table". While there are a couple of workarounds in version 20 that do similar things, the actual request could not be fulfilled this way. Plus, the workarounds were not as discoverable as we would have loved them to be as they included negative indents for line definitions and educated guesses on the number of detail records that are likely to be printed.This is going to change in version 21 – List & Label is going to support a new field type "table" which enables you to nest tables.
