Binding TreeGrid to XML Documents

This sample shows how you create a TreeGrid by using XML documents as a hierarchical data source for the FlexGrid control. It uses a DOMParser object to parse an XML string into a Document object and loops through the Document to build an array with "category" items, each with a "products" array. The array is used as an itemsSource and the childItemsPath property is used to show the products for each category as a TreeGrid.
