Thank you for contacting us.
The control is not designed to support empty values (records). Instead, you can have a special "Empty" item - e.g. at index 0 and whenever an empty value should be selected to specify that special item. For example:
.radListPicker1.SelectedIndex = 0;
// perform the actual selection
I hope this information is useful. Let me know if I can assist you in some other way.
All the best,
