XMLNodes.ContextEnter Event

Occurs when the cursor is placed inside one of the nodes or descendant nodes of the XMLNodes collection, from an area outside of the context of the node.

Namespace:  Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word (in Microsoft.Office.Tools.Word.dll)

Syntax

'Declaration
Event ContextEnter As ContextChangeEventHandler

event ContextChangeEventHandler ContextEnter

Remarks

The ContextEnter event differs from the Select event. The ContextEnter event is raised only when the context changes and can be raised for multiple XMLNodes controls nested at the same hierarchical level. For more information, see XMLNodes Control.

Examples

The following code example demonstrates event handlers for the Select, Deselect, ContextEnter, and ContextLeave events. When the Select and 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 ContextEnter and 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 XMLNodes collection named SampleInsertNodes.
