As we know, we may add an item to a data grid by just call
I wonder if there is a specific function like addItemAt(x:object, y:int) which takes an additional index number as parameter
Eventually, users wanna add a new row before or after the selected row in the data grid.
ArrayCollection subclasses ListCollectionView. ListCollectionView contains the function you are looking for , addItemAt( object:Object , index:int ).
If this answer was helpful , please mark it as such.
I tried and it worked.
