You can programmatically access and control the properties of the TreeView control. The TreeView can also be populated via client-side script on Internet Explorer 5.0 and later, and on Netscape 6.0 and later. In addition, nodes can be displayed as either plain text or hyperlinks, and you can optionally display a check box next to each node. 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 can be a parent node and a child node. A node that has no children is called a leaf node. A node that is not contained by any other node but is the ancestor to all the other nodes is the root node. The typical TreeView tree structure has only one root node, but you can add multiple root nodes to the tree structure. This means that you can display a tree hierarchy with out being forced to have a single root node. The TreeNode has a Text property that is populated with the data that is to be dis played. The TreeNode also has a Value property that is used to store the data that is posted back to the Web server. A node can be configured to be a selection node or a navigation node by setting the NavigateUrl property. If the NavigateUrl property is set to an empty string (string.Empty), it is a selection node, where clicking the node simply selects it. If the NavigateUrl property is not set to an empty string, it is a navigation node, where click ing the node attempts to navigate to the location that is specified by the NavigateUrl property.

The TreeView control can be populated using static data or by data binding to the control. To populate the TreeView control with static data, you can use declarative syntax by placing opening and closing <Nodes> tags in the TreeView element, and then creating a structure of nested <asp:TreeNode> elements within the <Nodes> element. Each <asp:TreeNode> has properties that you can set by adding attributes to the <asp:TreeNode> element. To use data binding to populate the TreeView control, you can use any data source that implements the IHierarchicalDataSource interface, such as an XmlDataSource control or a SiteMapDataSource control. Simply set the DataSourceID property of the TreeView control to the ID value of the data source control, and the TreeView control automati cally binds to the specified data source control.

You can also bind to an XmlDocument object or a DataSet object that contains DataRelation objects by setting the DataSource property of the TreeView control to the data source, and then calling the DataBind method. The TreeView control contains a DataBindings property that is a collection of TreeNodeBinding objects that define the binding between a data item and the TreeNode. You can specify the criteria for binding and the data item property to display in the node. This is useful when binding to XML elements where you are interested in binding to an attribute of the element.

The TreeView control performs client-side JavaScript callbacks when expanding nodes. A malicious user can craft a callback to get TreeView data that you may have tried to hide using the MaxDataBindDepth property, so don t use the MaxDataBindDepth as a means to hide sen sitive data.
