I have a collection class that is derived from CollectionBase. There is =
a property on my *Form Class* of type=3D MyCollection class. This form =
property has the following attributes:

<Editor(GetType(System.ComponentModel.Design.CollectionEditor), =
GetType(System.Drawing.Design.UITypeEditor)), =
DesignerSerializationVisibility(DesignerSerializationVisibility.Content)>=
_

Public Property Parameters() As UIWinScreenParametersCollection

At deign-time VS.Net displays the collection editor and allow us to =
input new items but items are not getting presisted. Is there any other =
attribute I have to use please ?

Thanks
