How to refresh the Datagrid in Flex 4?

Question

I am using ArrayCollection as the dataprovider to my datagrid and retrieving the information from MySQL using JSP and adding them to the ArrayCollection. I would like to transfer the selected item from one datagrid to other datagrid by changing the status of the file. As of know, am able to do this fine but I need to refresh the webpage manually for the updated results in both the datagrids.

I tried to do the following thing : dataGrid.invalidateDisplayList()

I called this method on both the datagrid's but it's not refreshing the datagrid, I still need to refresh my webpage for the updated results. Any ideas or suggestions would be greatly appreciated.

There is no need to refresh the DataGrid.

Just make your ArrayCollection variable Bindable which is your dataprovider of DataGrid. So, whenever you will make a change in your dataprovider(ArrayCollection) and it will be reflected on your DataGrid automatically.
