As with all data-oriented components, you rarely work directly with the component UI. Instead, you read and manipulate the underlying dataProvider.
All of the functions you note are available in the Collection APIs(ArrayCollection, XMLListCollection). Using XML, you have all of the functions except for removeNode, but for this you use "delete" as you have tried. This is the correct way to remove nodes. Delete can be a bit tricky. Use temporary vars and toXMLString() to ensure you have built the correct expression. Then use that expression (not the variable!) with the delete operator. I have not had much success using delete with XMLList and always ensure I am deleteing an XML node. No, there is no unique identifier automatically added to the dataProvider for the tree. You must do this yourself if you need it.

Hi All! I am have some odd experience with Flex Tree Control. I am new to the Flex Environment and working with three control. I am unable to find some basic functions for Three control Or I am unable to find them. 1. tree.lenth (Total number of nodes in the tree) 2. tree.Level (parent child level) 3. tree.RemoveNode() [Extreamly required help if you know some thing about this I tried to remove node but I am unable to remove the node of the tree. I use the following code public function RemoveNode():void { var node:XMLList = XMLList(targetTree.selectedItem); delete children[0]; } ] Further selected index of the treeItem changes when the node is expended and collapsed. Is there any unique identifier for each element? With Best regards YM
