On a weekly basis, it would be correct to use radio button instead of checkboxes , since the user can only select one of the options.

Either way, the implementation is exactly the same:

In the checked event of the element that defines the type of person (the checkbox ) you should do something like this

private void rbPessoaFisica_CheckedChanged(object sender, EventArgs e)
{
    txtDocumento.Mask = rbPessoaFisica.Checked ? @"000\.000\.000\-00" : @"00\.000\.000\/0000\-00";
}
