Hi,

I am new to component building and I'm trying to get some code to
execute when editing a TCollection property in the Object Inspector.
I'm using Delphi 2006 (excellent!).

In my component, I have created my own custom TCollection and my own
custom TCollectionItem object. When I drop my object on a form and
click on the property, the IDE displays the Collection Editor. What I
wish to do is execute some code just before the Delphi IDE displays the
Collection Editor.

Basically, I'm trying to copy the behaviour of the TADOStoredProc
"Parameters" property. In the Object Inspector, if you click on the
"..." button in the "Parameters" property, some code runs that
automatically populates this collection if there are no items present.
This code runs before the Collections Editor appears.

Does anybody know how to replicate this behaviour, or will I have to
build my own custom editor?

Thanks,

Larry
