I created a sample UserControl that exposes a Collection
Serialization works in this sample, the single problem I found is that I
want to have an edit updated with number of items in the collection. For
that I had to call Control.Refresh() when CollectionEditor.SetItems() is
called. Can you please use this sample and tell if it is close to what you
need?
Tip1: I have to restart VStudio 2005 quite often (almost each time I modify
control)
Tip 2: I use dbmon or DbgView (from
www.sysinternals.com) to see the output
of System.Diagonostics.Trace.WriteLine even if is in VStudio Designer
Here follows the source code

{

set { intValue = value; }
}
public String StrValue
{
get { return strValue; }
set { strValue = value; }
}
}
public class ValuesEditor : CollectionEditor
{
public ValuesEditor()
: base(typeof(List<TestData>))
{ }
protected override object SetItems(object editValue, object[] value)
{
System.Diagnostics.Trace.WriteLine("SetItems1");
System.Diagnostics.Trace.WriteLine("SetItems2: " + editValue);
object retValue = base.SetItems(editValue, value);
Control control = this.Context.Instance as Control;
System.Diagnostics.Trace.WriteLine("SetItems3: " + control);
if (control != null)
{
control.Refresh();
}
return retValue;
}
}

{

}
protected override void OnPaint(PaintEventArgs e)
{
this.textBox.Text = values.Count.ToString();
base.OnPaint(e);
}
}
}

and none of those things are helping. :/
this is the header I've already been using.

solution to this.

I think you should use RefreshPropertiesAttribute.

FooCollection FooProperties
