Re: TypeConverte: GetProperties Not fund in base in base

Rob,
You got it - Thanks for the help.
By the way do you know how to obtain the PropertySort for the 
"Context"?  If I do a break I can via the "Local Variables" window see 
a "data" item called "PropertySort" which includes the information if 
the user want to sort using Categories or strait Alpha.  However I an 
not sure how to get to this PropertySort.  I assume it is a part of 
GridEntry. Even with that information I am not sure how the IDE can get 
the value.  Any idea?

Which should be OK if you read the manual, online material, even 
samples
done in C#, but I still get the compiler error under Delphi 2005 Net:
[Error] OrderedPropertyGrid.pas(33): E2137 Method 'GetProperties' not
found in base class
In fact there are three GetProperties methods in the base class, but
none of them matches the signature of the method you show above, and so
the compiler is correct. The third parameter should be an array of
Attribute, not just one.
