Dataprovidername.refresh() method but it is not working.......please help me in this

Thanks to every one............

Answer 1

Did you make the XML-variable Bindable?:

[Bindable]
private var data:XML...

Answer 2

after updating the data, try dispatching a collection change event manually:

datagrid.dataProvider.dispatchEvent( new CollectionEvent.COLLECTION_CHANGE() );

Answer 3

I have solved my problem of refreshing data grid when data-provider XML is changed....

instead of saving the XML document and loading it to the data-grid data provider i assigned the updated XML Document to the data-provider as a new provider..In this way the refreshing problem, with binding can be solved.
