Reset all the items in a form

Question

I was wondering, is there a way I can reset all the checkboxes, textboxes, numerics and other controls back to the default values without writing code for every control individually? This is the code I've tried, but doesn't seem to work:

for (int i = 0; i < this.Controls.Count; i++)
{
    this.Controls[i].ResetText();
}

EDIT:
I've fixed it by manually setting the control values, sorry for all the trouble >.<.

Do as below create class and call it like this

Check : Reset all Controls (Textbox, ComboBox, CheckBox, ListBox) in a Windows Form using C#

private void button1_Click(object sender, EventArgs e)
{
   Utilities.ResetAllControls(this);
}

public class Utilities
    {
        public static void ResetAllControls(Control form)
        {
            foreach (Control control in form.Controls)
            {
                if (control is TextBox)
                {
                    TextBox textBox = (TextBox)control;
                    textBox.Text = null;
                }

                if (control is ComboBox)
                {
                    ComboBox comboBox = (ComboBox)control;
                    if (comboBox.Items.Count > 0)
                        comboBox.SelectedIndex = 0;
                }

                if (control is CheckBox)
                {
                    CheckBox checkBox = (CheckBox)control;
                    checkBox.Checked = false;
                }

                if (control is ListBox)
                {
                    ListBox listBox = (ListBox)control;
                    listBox.ClearSelected();
                }
            }
        }      
    }
