Collapse, expand, and nodeclick events also provide programming functions. 1. common attributes (1) The nodes attribute returns a reference to the Node object

Treeview controls are often used in Web development. A common operation is Traverse all nodes . However, the control itself does not provide this function. It is very cumbersome to manually write recursive access functions every time. So I wrote a simple help class to solve this problem, so that we don't need to use recursion to access it every time: Using

item is bound to a node in the TreeView control. Ii.

The TreeView control can use an XML document as a data source to display nodes based on the hierarchy of the XML document. The access to the XML document is done by the XmlDataSource control, specifying the XML document path from the DataFile property of the XmlDataSource control, and then setting the corresponding relationship to the nodes in the XML document in the Tr
