18. March 2009 20:19
So I got this idea last night to use an e4x expression as the source of a chart and advanceddatagrid dataProvider. I’ve found that mostly all of the “examples” online and in all the books only look at one or(at most) two nesting levels inside of an xml document. Unfortunately, ... [More]

Binding e4x to dataProvider

18. March 2009 08:54
Let's say you have a set of redio buttons that act to filter your data collection.  It is possible to bind the dataProvider property of Flex Charts and AdvancedDataGrid controls to an e4x value.  There are still a couple little glitches working this way that I haven't quite figur... [More]
