Determines whether the provided value is accepted for the type of property through basic type checking, and also potentially if it is within the allowed range of values for that type.
Assembly: WindowsBase (in WindowsBase.dll)
For a dependency property, an allowed range of values for that type can be specified through a ValidateValueCallback that is provided in the dependency property registration.
This method calls IsValidType internally. If the dependency property in question has no ValidateValueCallback,then calling this method is effectively equivalent to calling IsValidType. If the dependency property does have a ValidateValueCallback, and if IsValidType would have returned true, then the value returned will be as implemented in the callback.
A null value is a valid value for reference type dependency properties, or for a Nullable<T> dependency property, and would return true for these cases. In cases where the dependency property is neither a reference nor a Nullable<T> type, IsValidType will return false for a null value rather than raise an exception.
