Remarks
This method is called by the base implementation of the OnValueChanging and OnValueChanged methods. It calls the OnValueChanging method to determine whether the value is of a valid type. It calls the OnValueChanged method to set the type appropriately, based on the new value (unless the type was explicitly set otherwise).
The base implementation of this method calls GetTypeFrom on the object value and returns the .NET Framework type name.
