Component, Properties window and Object Collection Editor

Hello.

I am trying to create a component to Validate Controls in a Form. (i don't
like the IErrorProvider).

My point is that i am trying to create an item in the properties window
where i can click it and select the controls that i want to check and store
them in an Arraylist, so, whenever i feel that i want to check those
controls, i just call the arraylist and with a method that i have
implemented check on their properties.

Ok. i got to put the Propertie into the Properties window and when i click
the three dots button [...] it pops up the Object Collection Editor. That's
OK. When i click Add i can see a System.Object object added but with no
properties at all. Nothing. I add three more and when i click OK they are
not saved. Of course... I assumed that the object collection automatically
will add them to my araylist... but nothing seems to be happening.

Anyway, i have been looking for some tutorials or articles about this and
can't find anything.

Does anyone knows a lil bit about this?
