design time DataSource in VB

[Stephen]

IN VB.NET
I have a form with a ListBox and would like to set the DataSource property
at design-time but I can't seem to declare any kind of variable that will
show up in the list. I have tried a traditional array, ArrayList,
Collection as public vars in the Form Class's Declarations section. Setting
the DataSource property to any of these works fine at run time.

I want to do it at design time because after I change the Collection, it
doesn't update it in the ListBox, even though breaking showed that the
Collection.Count property had gone up. I first add to it in code with
Coll.Add("WHATEVER") and it shows up fine, before and after binding. But I
try
to do this: Coll.Add(TextBox1.Text) and it doesn't show up in the ListBox
but is apparently being added to the collection object just fine.

Any answer to either of these questions would be helpful
Thanks,
Stephen

Have you tried resetting the ListBox's DataSource after adding your item to
the collection?

Me.ListBox1.DataSource = mMyCollection

I have something similar where my collection object raises a List_Changed
event, and I respond by resetting the DataSource of the ListBox.
