Yes, do not use Array (or XMLList) as a dataProvider if you need to update it at run time. Neither of those dispatches the necessary events to update the visual controls. Use a collection.
You cannot use an associative array (Object) as a dataProvider.

Hi Paul, If you use an ArrayCollections as the dataProvider for the DataGrid instead, you can remove an item like so: myArrayCollection.removeItemAt( myDataGrid.selectedIndex ); The DataGrid's selectedIndex is the same as the index of the item in the ArrayCollection. -TH --- In [email protected], "tendancer2000" <tendan...@...> wrote: > > I have a datagrid with an Array dataprovider.

The better solution is probably to redesign my array, make it associative, but I am curious to know if there is a way to do it with what there already is. > > Thanks, and thanks to Alex for answering my previous question. > > Paul >
