Dailing with controls at runtime

Well, you will need to add the eventhandlers to your form at compile time. For example:

        private void myUserControl_MouseDown(object sender, MouseEventArgs e)
        {
            // code
        }

but you'll need to wire up these eventhandlers at run time.

So, if myUserControl denotes a reference to the user control you've created using reflection and added to the form's Controls collection:

       myUserControl.MouseDown += myUserControl_MouseDown;

You will, of course, need to add all this code to the form manually as the VS designer won't have any knowledge of the user control to be added.
