Hi Fabian and Stefan, we currently don't have a public roadmap, but I can answer some of your questions and shed some light on planned improvements.
* Having different filters in the header - planned 10.24
* Automatically select first row - planned for Q4 2025
On the way forward - Datagrid 1 will be deprecated with Mendix 11, but still usable for Dojo client applications. It is already not possible to use Datagrid 1 in a React client app, and with Mendix 12 we are planning to drop Dojo client completely.
We know the data widgets, in particular the DG2, is one of the most important widgets and we are constantly working on making it better. Some recent improvements include
* setting filters using NF
* searchable drop-down filtering (Combo box style)
* accessibility improvements (e.g. keyboard navigation)
* several DG2 specific improvements: Excel exports, improved personalization, reference set support, loading indicators, conversion from DG1
For the coming months, we are planning:
* grid-wide filtering improvements (having different filter types in the header)
* option to persist row selection through paging
* dynamic filters (compose filters at runtime)
* custom footer
* customizable pagination
* auto-select first row
* dynamic page sizing
* apply recent DG2 features to Gallery
* tree node improvements
I hope this answers your questions. Please note that although this is the current plan that we have, our roadmap is always subject to change.
