Here is a minimal sample that uses tableControlCurrentCellValidating to make sure your user never chooses a duplicate value in a combobox column.

Just for the record for anyone who might be trying to use this sample, I think the code that Inserts a new value should be changed to: uniquesList.Insert(-(loc + 1), k);

I attach a file that can resolve my problem and also control the rows number for no more than the items count in the dropdownlist.
