, if a function returns this value, it is prompted that the WPF property system should ignore the execution of this feature. For example, during the execution of a binding, if the execution result of the binding is unsetvalue, then the execution of the binding will be ignored. This is also true during the execution of the Coercevaluecallback function: If the Coercevaluecallback function executes as unsetvalue, then the assignment to the dependency property will be invalid.The last is the propert
