One way is to bind a variable to the selectedIndex of the DataGrid:
[Bindable]
private var selectedIndex:int = -1;
<mx:DataGrid selectedIndex="{ selectedIndex }"/>
Then when you filter the collection:
myCollection.filterFunction = myFilterFunction;
myCollection.refresh();
selectedIndex = (myCollection.length > 0 ? 0 : -1);
