The HitTestSelection method returns an InkCanvasSelectionHitResult to indicate which part of the selection adorner intersects or surrounds a Point. This is useful when performing drag-and-drop operations.
The following example demonstrates how use HitTestSelection to determine whether to create a DataObject to initiate drag and drop. To implement drag and drop between two InkCanvas objects, see How to: Drag and Drop Ink.
void InkCanvas_PreviewMouseDown(object sender, MouseEventArgs e) { InkCanvas ic = (InkCanvas)sender; Point pt = e.GetPosition(ic); // If the user is moving selected strokes, prepare the strokes to be // moved to another InkCanvas. if (ic.HitTestSelection(pt) == InkCanvasSelectionHitResult.Selection) { StrokeCollection selectedStrokes = ic.GetSelectedStrokes(); StrokeCollection strokesToMove = selectedStrokes.Clone(); // Remove the offset of the selected strokes so they // are positioned when the strokes are dropped. Rect inkBounds = strokesToMove.GetBounds(); TranslateStrokes(strokesToMove, -inkBounds.X, -inkBounds.Y); // Perform drag and drop. MemoryStream ms = new MemoryStream(); strokesToMove.Save(ms); DataObject dataObject = new DataObject( StrokeCollection.InkSerializedFormat, ms); DragDropEffects effects = DragDrop.DoDragDrop(ic, dataObject, DragDropEffects.Move); if ((effects & DragDropEffects.Move) == DragDropEffects.Move) { // Remove the selected strokes // from the current InkCanvas. ic.Strokes.Remove(selectedStrokes); } } }
