InkAnalyzer.ContextNodeReparenting Event
Occurs before the InkAnalyzer moves a ContextNode by changing its parent node.
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Use this event when your application maintains its own data structure, which is synchronized with that of the InkAnalyzer. This event occurs during the reconcile phase of ink analysis, or in response to an InkAnalyzer method that moves a ContextNode from one SubNodes collection to another.
For more information about synchronizing your application data with the InkAnalyzer, see Data Proxy with Ink Analysis.
This example defines a method, AttachDataProxyEventHandlers, that attaches data proxy event handlers to an InkAnalyzer, theInkAnalyzer.
Private Sub AttachDataProxyEventHandlers() ' If the document model supports on demand data proxy, then add an ' event handler for the PopulateContextNode event. This event is raised ' when the InkAnalyzer accesses a partially populated ContextNode created ' by the document model. If Me.theDocumentModel.SupportsOnDemandDataProxy Then AddHandler Me.theInkAnalyzer.PopulateContextNode, AddressOf Me.PopulateContextNode End If ' Add the other data proxy related event handlers. These events are raised ' by the InkAnalyzer to communicate ink analysis results to the document model.

The following example defines the method, ReparentContextNode, that handles the ContextNodeReparenting event. ReparentContextNode passes the event information to the document model object, theDocumentModel.
This example does not provide the definition of the document model or demonstrate how it processes the information passed to it.
