Commented Unassigned: PropertyGrid issue with ValueRangeTextBox [21655]

I am loading an object into the PropertyGrid, and I get the below error. I use the PropertyGrid for many other types, and just one type causes this exception. Doesn't the PropertyGrid only create textboxes for types that it can handle? Is there a way to find out which property/value is causing the exception?

InnerException: System.InvalidCastException
_HResult=-2147467262
_message=Object must implement IConvertible.
HResult=-2147467262

Hi,

Can you attach a sample showing the problem so we can reproduce to test?
Thanks.
