IDataErrorInfo Validation overridden by PropertyGrid

The Object that is being displayed by the PropertyGrid has its own IDataErrorInfo validation logic.

This object contains UInt16 types, which I want to validate. I looks like however that when this UInt16 value is out of range (-1 is typed into the text box), that the IDataErrorInfo Validation gets to it first and throw an exception.

When my validation processes it it see a valid value. This results in the internal exception message being displayed in the tooltip as opposed to my error message.

Is there a way to prevent this?


Here's the output from the debugger Output Window
