Hi lsmarco1973,
The provided code is invalid. There is no widget called JqxListBox. It is jqxListBox. Also there’s no method called “GetSelectedItem”, it is “getSelectedItem”. Note: Casing is sth. very important in JavaScript. The “getSelectedItems” method can be used for getting the items which are selected. The returned value is Array and each Array has “length” property which you can use for getting the items. Ex: http://jsfiddle.net/bg6kr/1/
