Great and simple solution.
Just one side note, if you change the dataprovider of the datagrid the sorting will be lost. In order to avoid this you can use a ListCollectionView as the dataprovider of the datagrid and assign your ArrayCollection data to the ‘list’ property of the ListCollectionView. Then if you need to change the dataprovider you only modify the list property and the dataprovider of the datagrid is not reset, and the sort is preserved.

This neat hack is totally unnecessary if you use an instance of ListCollectionView as your dataProvider because you can accomplish this by setting the sort property of your collection as shown below. Your suggestion would also reset the sort column if/when data is reloaded from the server. Thus you should create your collection and set the default sort field during initialization, then populate your collection anytime data is loaded from an external source, which will preserve the user’s chosen sort columns when data is reloaded.

However, I’ve found that if you have to set a custom sort function, then the DataGrid and AdvancedDataGrid doesn’t show the ascending/descending marker by default even though the data is properly sorted. I tried your suggestion to see if it would resolve my issue, but unfortunately it does not work either.

[code]

import mx.collections.Sort;
import mx.collections.SortField;
import mx.collections.XMLListCollection;

private accounts:XMLListCollection;
private function init():void {
accounts = new XMLListCollection();
accounts.sort = new Sort();
accounts.sort.fields = [new SortField("name", true, false, false)];
accounts.refresh();
}

[/code]

Thank you so much! That’s a perfect little snippet I pasted right into my code.

Just wanted to say thanks for this, too. Bizarre that this is not a built-in feature, though…

You can define the first sort like ASC or DESC setting the propertie sortDescending in datagrid. True for descending or false for ascending. I think that is a better solution than dispatch two events.
