I tried something similar to this and got the value to save, however, only when I reset the bindingsource and bindingsourcemember. What I want is to have the business rule be able to associate the failure of the business rule with this control so that the error icon appears when an invalid value is entered.

Whenever, I add values for these binding properties, the textbox always reverts to zero, even in your proposed solution.
