The last time I talked about how to support the infinite number of Dynamically Loaded Treeview controls and how to prepare the server data. However, it is just a small demo instance. In actual use, the data on the server may be completely different, but no matter how it changes, make sure that the request/response structure of the tree data can be formed.

The example in the previous section only demonstrates the basic framework of the TreeView program and does not include any data. In this example, we need to add our own data. First, should the data be added to that object? By the way, it is the ListStore Class Object musicList. We want to add data to it. The following code adds two rows of data: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Musiclis
