I'm editing this, because I'm rethinking my problem, and I think I need help with the regular expression and that is the actual problem. I need a regular expression that can validate a RadMaskedTextBox. It has the following rules:
1. numeric only
2. minimum and maximum characters of 9
3. the same number can not be typed over and over like 111111111
4. no sequential numbers ascending like 123456789
5. And no sequential numbers descending like 987654321
Can anyone help me with this?
