> the controls bound to the binding source get the value changed event

Ouch. What kind of controls are these? It would seem that the Value properties of these controls do not check that the value was actually modified. If these are controls developed by you, consider revising the Value setter so that the event is only raised if the new value for the backing field differs from the old value.

If you cannot modify the controls, then you'll need to keep track of the old values on the side and do the comparison yourself in the event handler to detect the spurious events.

Hi mlde,

When you bind some controls with the same object, you will be notified when the property value is changed. That cannot be apply to part of these controls but to all. If you don't want some control receive the change, you'd better do not use binding for these control.

The function of binding is to keep all the controls bind to the same source get data changed synchronously.

Sincerely,
Kira Qian
