All,
I have 2 rad list boxes working in tandem (boxA, boxB)... and I have some list items that are mandatory selections that must always remain in boxB and never be removed.
On the server side I populate boxA and then automatically add mandatory list items in boxB.
Next, I prevent users from transfering a mandatory item from boxB back to boxA via client side code.
I have devised a way to enforce this functionality (using OnClientTransferring ) for a single transfer from boxB to boxA, but I am not sure how to approach enforcing this for a "Transfer All" / "All to Left" transfer. Please see attached.
If someone could provide some direction here it would be appreciated.
Thanks,
Jai
