InkPicture.SelectionChanging Event
Occurs when the selection of ink within the InkPicture control is about to change, such as through alterations to the user interface, cut-and-paste procedures, or the Selection property.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public Event SelectionChanging As InkOverlaySelectionChangingEventHandler
'Usage
Dim instance As InkPicture
Dim handler As InkOverlaySelectionChangingEventHandler
AddHandler instance.SelectionChanging, handler
public event InkOverlaySelectionChangingEventHandler SelectionChanging
public:
event InkOverlaySelectionChangingEventHandler^ SelectionChanging {
void add (InkOverlaySelectionChangingEventHandler^ value);
void remove (InkOverlaySelectionChangingEventHandler^ value);
}
JScript does not support events.
Remarks
The event handler receives an argument of type InkOverlaySelectionChangingEventArgs that contains data about this event.
When you create an InkOverlaySelectionChangingEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For performance reasons, the default event interest is off but is turned on automatically if you add an event handler.
Examples
In this example, the SelectionChanging event handler prohibits the selection of multiple strokes by removing all but one Stroke object from the current selection.
Private Sub mInkObject_SelectionChanging(ByVal sender As Object, ByVal e As InkOverlaySelectionChangingEventArgs)
While e.NewSelection.Count > 1
e.NewSelection.RemoveAt(e.NewSelection.Count - 1)
End While
End Sub
private void mInkObject_SelectionChanging(object sender, InkOverlaySelectionChangingEventArgs e)
{
while (e.NewSelection.Count > 1)
{
e.NewSelection.RemoveAt(e.NewSelection.Count - 1);
}
}
