listgrid grouping without using datasource?

[3.2]

Hi!

I have a listgrid and I have a recordlist set to the listgrid as data.
It works fine.
However, Im not able to group the list by a field. If I use the listgrid.setGroupByField() function
or If i try to use the groupBy() function I get an exception says:

can't getSelectedState without a DataSource with a primary key field set

I guess thats because I dont use a Datasource.

So my question is: is there a way to group a listgrid without using datasource?

*bump*

anyone?

You can create a local Datasource very easy and have all the benefits of data-binding controls (such as the grouping feature)

Check the documentation for all available sources of data to feed a datasource.
