    To fix this issue you need to add an attribute to your properties:

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

    But, I think you're using a UserControl in the wrong way. A UserControl should follow the encasulation rules and not expose its internal objects (what happens if you set the TextBox to null?), so expose only the properties you need, for example:

    exposing a label text in the head of the control. 

    public string HeaderText

    {

       get { return lblHeader.Text;}

       set { lblHeader.Text = value; }

    } 

    To set the font of all controls in the UserControl, just change the UserControl font and it will effect all its children font.
