Re: User v Custom Controls

User controls are derived from UserControl and thus inherit the
infrastructure to contain other controls (e.g. you can create a new user
control containing buttons, list views, etc, all with Designer support).
Custom controls inherit from Control and thus have no container facilities.

You normally use user controls if you want to create a new control as a
compound of other controls (i.e. like a form, but reusable), custom
controls if you create a new control from scratch, even drawing it
yourself in its OnPaint method.

Where's the problem?

ArrayList __gc * l = new ArrayList();
l->Add(S"Test1");
l->Add(S"Test2");
l->Add(S"Test3");
comboBox1->DataSource = l;

What do you want to use the user control or custom control for?
