Hi, I've committed/pushed code that makes TreeGrid work. You can look at TreeExample to see how to use it. Basically, TreeGrid is just like DataGrid except it works with HierarchicalData. You define which column you want to hold the tree using a <js:TreeGridColumn> description. For the other columns use <js:DataGridColumn>. You can make any column be the Tree. You can even have multiple columns be trees, although I'm not sure if that makes any sense.
There is still some more work and styling to be done. Regards, Peter Ent Adobe Systems/Apache Royale project
