Answer 1

The AcceptButton is a property of Form and cannot be used for the UserControl. You can simply override ProcessCmdKey though and this will work so long as the user control has focus. Otherwise you will need to use the AcceptButton of the form separately or override the ProcessCmdKey in the form if you have multiple controls which could be active.

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData) 
  {
      if (keyData == Keys.Enter) 
      {
        button.PerformClick();
        return true;
      }
      return base.ProcessCmdKey(ref msg, keyData);
    }

Answer 2

If you set the Modifier property on the button to "Public", you can use the button as AcceptButton on the form. Unfortunately you cannot do it design-time with the properties window of Visual Studio, but you can do it in code.

    public Form1()
    {
        InitializeComponent();
        this.AcceptButton = userControl11.button1;
    }
