Event Type
Examples
The following example prevents any strokes rendered as highlighters from being erased. The example assumes that the InkCanvas is connected to the event handler.
void inkCanvas1_StrokeErasing(object sender, InkCanvasStrokeErasingEventArgs e)
{
if (e.Stroke.DrawingAttributes.IsHighlighter)
{
e.Cancel = true;
}
}
Private Sub inkCanvas1_StrokeErasing(ByVal sender As Object, _
ByVal e As InkCanvasStrokeErasingEventArgs)
If (e.Stroke.DrawingAttributes.IsHighlighter) Then
e.Cancel = True
End If
End Sub
Remarks
Handle this event when you want to check whether a stroke should be erased. Set the Cancel property to true
if you want to prevent the stroke from being erased. You can use this technique when the EditingMode or EditingModeInverted property is set to EraseByStroke or EraseByPoint.
