I am trying to add new items to a Radlist control. I have updated the list which is the data source for the radlist control. When i do the rebind. the new items not showing in the list control.But I can see the datasource(list) has the new item(s) added.I have attached the sample code here. Add button should add the new items to list control. I also wants to achieve if any item(s) double clicked in the list control should be removed from it.Please provide me a sample for that as well.I also wants to keep the dropdownlist list by default as not selected any items(blank) .
Thanks in advance
