Just use the selectedIndex property of the DOM element: alert($(“#dropDownMenuKategorie”)[0].selectedIndex); Update: Since version 1.6 jQuery has the prop method that can be used to read … Read more
For directly clicking on a DataPoint you can do a HitTest. But for tiny points or for a selection of a range this will not work well. The necessary functions are hidden in the Axes methods. This solution uses a regular rubber-band rectangle to select the points caught: Point mdown = Point.Empty; List<DataPoint> selectedPoints = … Read more
