Hi everyone,
I would like to know how I can achieve setting up grouping on a table linked to a DataCollection.
If I pass directly the data to the table, it works:

Otherwise if I pass the data to the DataCollection, or load it via an Ajax request, it doesn’t work:

Anyone has a idea on what I should do to have a treetable grouped by using a DataCollection (or TreeCollection maybe) ?
Thanks a lot
up
Hello!
So here are several solutions:
Without DataCollection the solution will look like: https://webix.com/snippet/83b7599d
As collection is not a plain data array, parse(collection) uses different logic to transfer the data from the collection to the datatable. In such case, $group will not be called. You can call property group after parse() which is groups data by the specified data property.
Please, check the snippet: https://webix.com/snippet/bf066a9e
If you work via an Ajax request, so it’s better to use instead of parse - sync with callback.
Here is an example: https://webix.com/snippet/ce5e1219
Thank you for your answer Nastja, the third one is exactly what I was looking for!
