bool isStrictMatch = false; string patternStrict = @"^([a-zA-Z]+)$"; Regex reStrict = new Regex(patternStrict); if (txtSecond.Text.Trim() != string.Empty) { isStrictMatch = reStrict.IsMatch(txtSecond.Text.Trim()); if (!isStrictMatch) MessageBox.Show("Please use alphabetics", "Validation", MessageBoxButtons.OK); }
