Adding items in collection property during design mode

[Saimeera]

Hi,

I am creating a custom control in asp.net 2.0. I want to add items in
the collection property when i set the value for a property name 'code'
during design mode.

I can able to add items in the collections property. But problem is
that when i switch to HTMLview, The items are once again added in the
collection property.(atlast same items are added twice in the collection
property)

I also cleared the items in the collection property. Still those items are
added once again.
