Filter GridView

Hello,
Is it possible to filter the content of a GridView in dthmlxScheduler ?
On this exemple http://docs.dhtmlx.com/scheduler/samples/03_extensions/27_grid_view.html it’s possible to display the events from a date to another date.
I would like to display events in the GridView where in the xml file the column detail equals for example ‘type1’ and only ‘type1’ not others.
How can I do that ?
Regards.

Dates of grid-visible range

Event filtering ( works for all views )

You can define function like

scheduler.filter_grid = function(id, event){ if (event.detail == "type1") return true; return false; }
