"Thanks for ideas."
How's this for one... either use a combobox, or roll your own spinner to use a dataprovider on your form containing all the task numbers (so all the controls are bound to the same dataprovider). Now whenever a control selects a number, remove the number from the dataprovider (or add it if you choose a different one), so the other controls have a reduced set of numbers to play with. There is a myriad of ways I can think to do this (and have some fun with it!) Gk.
