constructor on type "" not found when inheriting forms c# forms

created a form that inherits from another form, but for some reason I am getting the error constructor on type "baseForm" not found. This is the inheriting class constructor:

public partial class loadHtmlFormsDatabaseForm :      NEA_Official.createHtmlFormsForm
{
    List<field> listOfFields = new List<field>();
    static string username1;
    int originalListOfFieldsCount;
    htmlFormsProject loadedProject;

    public loadHtmlFormsDatabaseForm(htmlFormsProject loadProject, string username) : base(username1)
    {
        username1 = username;
        loadedProject = loadProject;
        InitializeComponent();
    }

This is the constructor for the base class:

    public partial class createHtmlFormsForm : Form
{
    List<field> listOfFields = new List<field>();
    string username = "";

    public createHtmlFormsForm(string username1)
    {
        username = username1;
        InitializeComponent();
    }

You can fix it by overload the constructor with no parameter in base class like this:

public partial class createHtmlFormsForm : Form
{
 List<field> listOfFields = new List<field>();
 string username = "";

 public createHtmlFormsForm(string username1)
 {
    username = username1;
    InitializeComponent();
 }
 public createHtmlFormsForm()
 {
    InitializeComponent();
 }
}

If you don't need constructor with no parameter you can create it private :

public partial class createHtmlFormsForm : Form
{
 List<field> listOfFields = new List<field>();
 string username = "";

 public createHtmlFormsForm(string username1)
 {
    username = username1;
    InitializeComponent();
 }
// private contructor with no parameter
 private createHtmlFormsForm()
 {
    InitializeComponent();
 }
}

or you can use Obsolete Attribute:

public partial class createHtmlFormsForm : Form
{
 List<field> listOfFields = new List<field>();
 string username = "";

 public createHtmlFormsForm(string username1)
 {
    username = username1;
    InitializeComponent();
 }

 [Obsolete("Designer only", true)]
 public createHtmlFormsForm()
 {
    InitializeComponent();
 }
}
