Strokes.StrokesAdded Event

Occurs when one or more Stroke objects are added to the Strokes collection.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink (in Microsoft.Ink.dll)

public event StrokesEventHandler StrokesAdded

The event handler receives an argument of type StrokesEventArgs containing data about this event.

When you create a StrokesEventHandler delegate, you identify the method handling 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.

In this example, a StrokesAdded event handler rotates newly added strokes clockwise 90 degrees. The rotation occurs around the center of the bounding box of the newly added Stroke object.

// Reminder: To avoid a memory leak, you must explicitly call the Dispose() method  
// on any Strokes collection to which an event handler has been attached before  
// the collection goes out of scope.  
private void Strokes_StrokesAdded(object sender, StrokesEventArgs e)
    // check each stroke id passed to the handler 
    foreach (int id in e.StrokeIds)
        // find the Stroke 
        foreach (Stroke oneStroke in (Strokes)sender)
            // when we find the added stroke, rotate it  
            if (oneStroke.Id == id)
                Rectangle bounds = oneStroke.GetBoundingBox();
                // create a point at the center of bounding box
                Point center = new Point(bounds.Left + (bounds.Width / 2), bounds.Top + (bounds.Height / 2));
                // rotate the stroke
                oneStroke.Rotate(90, center);
