InkCanvas.StrokeErasing Event

Occurs just before a user erases a stroke.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
'Declaration
Public Event StrokeErasing As InkCanvasStrokeErasingEventHandler
'Usage
Dim instance As InkCanvas 
Dim handler As InkCanvasStrokeErasingEventHandler 

AddHandler instance.StrokeErasing, handler
<object StrokeErasing="InkCanvasStrokeErasingEventHandler" .../>

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.

The following example prevents any strokes rendered as highlighters from being erased. The example assumes that the InkCanvas is connected to the event handler.

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

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
