Loading Data from Multiple Source.

I am loading two different type of data from two source. one source contain 4 columns(controls) and another source contain 8 columns(read-only controls) in month, week dates view. but in year and grid view i want to show only editable data (datas from first source not from second source).
how to do this?

have you checked a filtering api? docs.dhtmlx.com/scheduler/filtering.html

i want to put serial no in the gridview.
