Describe TreeView control in ASP.NET?
The TreeView control is made up of nodes. Each entry in the tree is called a node and is represented by a TreeNode object. A node that contains other nodes is called a parent node. A node that is contained by another node is called a child node. A node that has no child nodes is called a leaf node. A node that is not contained by any other node but is the ancestor to all the other nodes in the root node. A node can be both a parent and a child, but root, parent, and leaf nodes are mutually exclusive. Several visual and behavioral properties of nodes are determined by whether a node is a root, parent, or leaf node.
