FormClosing Treatment ErrorProvider

Question

I ran into a problem closing a form where my ErrorProvider wouldn't let me do it. To correct it I made a jerry-rigged creating a variable Boolena to confirm if the form was being closed. I had already tried FormClosing but still the ErrorProvider was validating the focus field. Has anyone had the same problem? How did you solve it? I wanted to do it more elegantly.

Form Initialize

public partial class MyForm: form
{
  private bool _isClosing = false;
...
...
}

Generic Validate With Error Provider

private bool ValidatingFields(Control control)
{
  bool eventArgs = false;
  if (!this._isClosing) //Boolean Variable jerry-rigged
  {
    
    if (string.IsNullOrEmpty(control.Text))
    {
      eventArgs = true;
      control.BackColor = Color.Red;
      errorProvider.SetError(control, "Campo Obrigatório!");
    }
    else
    {
      eventArgs = false;
      errorProvider.SetError(control, null);
    }
 }
 return eventArgs;
}

Field Validating

private void textName_Validating(object sender, CancelEventArgs e)
{
  e.Cancel = ValidatingFields(textName);
}

Event Close Button Click

private void btnCancel_Click(object sender, EventArgs e)
{
  this._isClosing = true;
  this.Close();
}

Yeah Nothing wrong in this behavior. Control Validation will trigger any button click event except who's CausesValidation = False. In short you can set this property of the cancel button to "False". This will skip the validation.
