I would create a [Bindable] instance variable typed as XMLListCollection and bind the dg.dataProvider to that.
Then, in the button handlers, set the bound variable: var xlFilteredData:XMLList = userXML.(category=='guest'); _xlcData = new XMLListCollection(xlFilteredData); Tracy ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of donvoltz Sent: Tuesday, September 11, 2007 10:21 AM To: [email protected] Subject: [flexcoders] Filtering XML best practices Hi Everyone, I have been using a master XML file containing about 120 usernames and additional information. Currently using custom renderers and a datagrid, I am displaying all of the users. What I would like to do is add buttons along the top of the datgrid to filter this XML into 4 - 5 different groups based on a category designation in the XML. My question about this is what is the best practice way to do this? Should I create a new XMLListCollection that filters the master list for each of the categories or can I add e4x filtering directly into the databinding property of the datagrid using actionscript and a custom event when one of the "filter" buttons is pressed. I have not been able to get this second method to work so I am unsure if this is possible. (this is what I have tried to do in the datagrid tag dataProvider = "{userXML.(category=='guest')}") Thanks for any help and guidance Sincerely, Don
