I think my question is more a proposed change request for the behaviour.
In the OnBeforeResHeaderRender event there is a DataItem in the event data available.
I fill the ResourceCollection manually by creating Resource objects and setting the needed data. But if I set the DataItem property (which is get; set; enabled) I still do not get this dataitem in the event. In the documentation it says that this field is only available if filled by calling LoadResources().
I think it would be nice to change this to enable user to transport some additional data that might be interesting for rendering.
In my case I have a 2 level tree. 1st level is the group name and second level are the people in the group. Now I would like to determine if I render the group header or the person header to give it different style.
Is there another way to get some more info to the event?
Thanks in advance
