I have a Main.mxml that has a DG, I have a component that has a DG. both are filled with different arrayCollections. I want to select a row in the top one and filter the arrayCollection in the component. How do you refresh an arrayCollection from a top document - parentDocument?
I think I have the filter all set just need to fire a refresh but I dont know how to do a refresh from a seperate component. I use the itemClick(event) from the first DG.
The refreshing ot the datagrid is the responsibility of a presentation or manager component , not a view component.
If i was at your place, i would have tried for Event propogation, by
dispatching an event from child component to parent component.
And if you want any changes in child component, you could bind the objects /
array collection or variables that supports binding between components.
