TreeNode.Checked Property
Assembly: System.Web (in system.web.dll)
When a node displays a check box, the Checked property is commonly used to specify whether the check box is selected. When the check box associated with a node is selected, the node is automatically added to the CheckedNodes collection of the TreeView control. The Checked property can also be used to determine whether the check box is selected.

| It is more common to determine which nodes in the TreeView control have their check boxes selected by iterating through the CheckedNodes collection. |
The value of this property is stored in view state.
The following code example demonstrates how to use the Checked property to specify whether a node's check box is selected. It initializes the check boxes of nodes with a depth of one to a selected state. For this example to work correctly, you must copy the sample XML data below to a file named Newsgroup.xml.
The following code is sample XML data for the previous example.
