Dynamic loading of tree data while expanding node using serv

Suite and Optimus Suite 5
#1

I have a tree with multiple levels, each will have thousands of nodes. I am trying to load entire tree at a single shot. But its taking lot of time to load. So what i need is i need to load the child nodes when i am exapanding parent node.



I heard we can do by using

tree.setXMLAutoLoading(url);

tree.loadXML(“root.xml”);



But i don’t have static xml file. I have to get the data from the database. I have some questions regarding above 2 lines of code.



1. Is root.xml will contain all the nodes information or only the parent node information.

2. When we are calling setXMLAutoLoading(url) - will this return only the child nodes of a expanding parent node or all the nodes information.

3. How it will understood i am expanding so and so node.



Thanks in advance…

Hello,


>> But i don’t have static xml file. I have to get the data from the database.


you can generate xml stream on server - the data from the database will be used to create this stream.


>> tree.loadXML(“root.xml”); Is root.xml will contain all the nodes information or only the parent node information.


instead of root.xml there can be path to the server-side script that generates the tree structure that will be loaded initially

Please, see the article about dynamic loading and sample:
