Hello, I just updated the Telerik controls to version 2012.2.607.35 and it seems that the ability to transfer items between radcomboboxes has changed. I have two radcomboboxes, one with all possible choices and the other with previously selected choices which are loaded during Page_Load. I can add and remove new items to the list of previously selected items, but I am now unable to transfer existing items (added during the Page_Load event) out of it. This had been working prior to installing the new version. If I add a delete button I am able to remove them. I have verified that this isn't caused by any changes I made by updating the Telerik controls in an old project that uses this same structure and recompiling with no other changes, the functionality is then lost.

Can this be fixed, or is there a way I can work around it?

Thanks,
John

I made up a sample project where I was able to replicate the problem. As I was playing around with it I noticed a property I hadn't seen before; to allow duplicates in transfer destination. This was set to the default value of false. I had been loading the entire list of values in the left box and a sub set in the right box. Since the values on the right side already existed on the left side it wouldn't let me transfer them back. It didn't behave this way before. I ended up just loading the left side with everything except for the sub set of previously selected values and now it works properly again.

Thanks,
John
