Hi…
Thanks for this tutorial, but i wanna know if this code can be used to be data provider for datagrid?
how to find data in datagrid if datagrid has sorted by clicking the header, and arraycollection is not sorted like datagrid did.

Ok, The answer is on the cursor.findAny line you need to specify the field name. Using the example above:

var found:Boolean = cursor2.findAny({Territory: ”Arizona”});

I am trying to do something similar only with an ArrayCollection that is setup like this:

new ArrayCollection([{Region:"Southwest", Territory:"Arizona",Territory_Rep:"Barbara Jennings", Actual:38865, Estimate:40000}, {Region:"Southwest", Territory:"Arizona", Territory_Rep:"Dana Binn", Actual:29885, Estimate:30000}]);

So then I made a simple test function:

private function testDpfind():void {
	var sortField2:SortField = new SortField("Territory", true);
            var sort2:Sort = new Sort();
            sort2.fields = [sortField2];
            dpFlat.sort = sort2;
            dpFlat.refresh();
            var cursor2:IViewCursor;
            cursor2 = dpFlat.createCursor();
	var found:Boolean = cursor2.findAny("Arizona");
	mx.controls.Alert.show("Hey",""+found);
}

Every time it throw this error: "Error: Find criteria must contain at least one sort field value." Why wouldn't this work?
