Exposing usercontrol components at design time

Hi,

I want to allow design time modification of components on a usercontrol. I
added a listview called listView1 to the usercontrol, then added this
accessor method:

[Category("Components"),
Description("Set the listview parameters."),

DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public MyListView ListView
{
get { return listView1; }
}

This works great, almost. When the usercontrol is added to a form, I can
edit the ListView properties. Unfortunately, this line of coded is added to
my form's InitializeComponent() method:

this.userListView.Controls.Add(this.listView1.ListView);

I've read that usually you have to expose each property individually, but
exposing the entire control works except for the redundant "Add" above. And
with DesignerSerializationVisibility.Content I didn't expect the control
itself to be serialized, just the contents. If I delete the line above
everything is fine, but of course I don't want to have to edit
InitializeComponent().

Is there a way to eliminate the redundant listview "Add()"?

Thank you,
Gary
 
You can try applying the DesignerSerializationVisibility.Hidden attribute to
the Controls property of your USerControl.

Wow! That seems to do what I need! The name of the UserControl listview does
not get updated in the properties window until I reload the form, but I can
live with that given how simple the solution is.

I applied the DesignerSerializationVisibility.Hidden using the following
code - is this the proper way to do it?

Thanks so much,
Gary

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public new ControlCollection Controls
{
get
{
return base.Controls;
}
}
