I am using a RadListBox for adding and deleting items. To delete the item from the list i use: "listBox.deleteItem(selectedItem);" and items are deleted from the list successfully. After adding items and deleting all of the items (leaving no items in the list) , an ajax call i make fails, and does not reach the required function on the server side. if no items are added to the list, or some items are added to the list, or some items are added and some are deleted but not all of the items the ajax call succeeds. The exception i receive is: "Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index "
Thanks for the help in advance.
