Tutorial: AX2012 - A new way of accessing the QueryBuildDataSource for a particular FormDataSource

When playing with some X++ code, I found an interesting addition that happened in AX 2012 related to form development.

There are 2 new methods that were added to the FormDataSource class, which allow you to very easily and error-free access the underlying QueryBuildDataSource, whether that is for the initial form query or for the queryRun that also contains user filters and sorting.

So, for example, instead of writing:

this.query().dataSourceTable(tableNum(InventTableModule), 2);

you can use the 2 new methods:


It might seem as a very minor improvement, but in reality it greatly simplifies maintenance of code on forms, when new datasources are added or existing ones removed/renamed.

That's all for today.
