InkCanvas.SelectionMoving Event

 

Occurs before selected strokes and elements are moved.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Event SelectionMoving As InkCanvasSelectionEditingEventHandler

This event occurs after the user requests that a selection of strokes and/or elements be moved, but before the change is applied.

The event handler receives an argument of type InkCanvasSelectionEditingEventArgs with two properties: OldRectangle and NewRectangle. OldRectangle defines the boundaries of the selection before the move and NewRectangle defines the boundaries of the selection after the move.

After the change is applied, the SelectionMoved event will occur.

The following example prevents the user from moving selected items vertically on an InkCanvas.

Private Sub inkCanvas1_SelectionMoving(ByVal sender As Object, _
                               ByVal e As InkCanvasSelectionEditingEventArgs)

    ' Allow the selection to only move horizontally.
    Dim newRect As Rect = e.NewRectangle
    e.NewRectangle = New Rect(newRect.X, e.OldRectangle.Y, newRect.Width, newRect.Height)

End Sub 'inkCanvas1_SelectionMoving
