The IncrementalLassoHitTester hit tests strokes by determining whether a lasso path surrounds it. Use the AddPoints method in the stylus events to add the points to the IncrementalLassoHitTester. When the points added to the IncrementalLassoHitTester selects or unselects a Stroke, the IncrementalLassoHitTester raises the SelectionChanged event
The following example demonstrates how to dynamically select strokes in a custom control. For the entire sample, see How to: Select Ink from a Custom Control
Sub selectionTester_SelectionChanged(ByVal sender As Object, _ ByVal args As LassoSelectionChangedEventArgs) ' Change the color of all selected strokes to red. For Each selectedStroke As Stroke In args.SelectedStrokes selectedStroke.DrawingAttributes.Color = Colors.Red selectedStrokes.Add(selectedStroke) Next selectedStroke ' Change the color of all unselected strokes to ' their original color. For Each unselectedStroke As Stroke In args.DeselectedStrokes unselectedStroke.DrawingAttributes.Color = inkDA.Color selectedStrokes.Remove(unselectedStroke) Next unselectedStroke End Sub 'selectionHT_StrokeHitChanged
