      this.ValidateTextBox(ValidateType.IS_EMPTY, PostValidate);
  }

  private void PostValidate()
  {
      MessageBox.Show("Field is Required");
  }

ValidateType.IS_EMPTY - Verify if the TextBox is empty
PosValidateAction - The method that will run after validation

Custom validator

  private void btnSave(object sender, EventArgs e)
  {
      this.ValidateTextBox(ValidateType.NONE, PostValidate, c =>
                  string.IsNullOrEmpty(c.Text) && c.Tag.Equals("Required"));
  }

  private void PostValidate()
  {
      MessageBox.Show("Field is Required");
  }

ValidateType.NONE - Indicate that none validate it will be executed
PosValidateAction - The method that will run after validation
c => string.IsNullOrEmpty(c.Text) && c.Tag.Equals("Required") - Condition to validate a TextBox, you can put anything.
