Currently the Kendo UI ListBox does not keep the order of its hidden select element and its options the same as the visible items. Since the form elements are posted in a form, we need to ensure the order matches. One way you can achieve that is by adding a Reorder() event handler function:
dataSource = e.sender.dataSource;
dataItem = e.dataItems
index = dataSource.indexOf(dataItem) + e.offset;
+ dataItem.uid +
If you would like to see the Kendo UI ListBox keeping its items and its select options in sync, I can easily convert this forum thread to a feature request so people can upvote it. The more popular a feature gets, the sooner we start working on it.
Let me know if you would like to do that.
