you can use holding event image. have note holding event wont fired desktop apps instead have use righttapped event. if targetting mobile apps can use holding event

 //  imageitem.righttapped += imageitem_righttapped;             imageitem.holding += imageitem_holding;             imageitem.isrighttapenabled = true;             imageitem.isholdingenabled = true;   private void imageitem_righttapped(object sender, righttappedroutedeventargs e)         {             mycanvas.children.remove(sender image);         }          private void imageitem_holding(object sender, holdingroutedeventargs e)         {             mycanvas.children.remove(sender image);         }
