Examples

The following code example demonstrates event handlers for the XMLNode.Select, XMLNode.Deselect, XMLNode.ContextEnter, and XMLNode.ContextLeave events. When the XMLNode.Select and XMLNode.Deselect events are raised, the event handlers add double lines to the borders of the selection or remove the double lines, depending on the event. When the XMLNode.ContextEnter and XMLNode.ContextLeave events are raised, the event handlers display messages that state the names of the newly selected node and the previously selected node. This example assumes that the current document contains an XMLNode named CustomerNode.
