editing data outside the widget

I intend to edit data in a form outside the widget (after selection in the widget this form will contain the values of the selected row and pressing a validation button would modify the row inside the widget).

How to modify the widget without refreshing it, and without modifying scrolling?

Thanks you for your beautiful work.

You can refresh a single row (after change array data) by:
obj.getRowTemplate(row#).refresh();
or a single cell by:
obj.getRowTemplate(row#).getItemTemplate(col#).refresh();

great
