I don't know if site & displayRectangle always occurs in properties, when
their BrowsableAttribute is Browsable=true.
What make those property unique, so I can check not only by their name, and
delete them from my list, but by some attributes, or something else ?

Thanks :)

Armin,

I have seen endless times here Herfried replying about the browsable
attribute, and I've almost the same times written that it does not make a
property invisible in a property grid.

I also think it should do that, so I don't know what Net versions that were
and if it is currently doing what you would expect.

At least I was never able to make a public property invisible in the grid.
And then come forever with the sample background from a picturebox, which in
fact does nothing and would be better not in the property grid of the
designer.

I don't know what makes them unique or why you think they are unique. They are
properties like others and browsable=true. Therefore they are listed. You can
check all their attributes by calling GetCustomAttributes.

I've never used the PpropertyGrid. :-D

I've only read the documentation and counted the # of properties in the
property window in the IDE if I select a picturebox or a panel in the Form
designer.

I don't challenge the whole task every time. ;)

I've only shown you the part you've asked for. I don't write the final code.
You should combine my information with what you already have. I guess you've
ignored 'CanWrite' this time. DisplayRectangle is readonly.
