Some control to Validate in asp.net

[Guest]

I need to validate that a user enters (in a TextBox) only the values 1, 2, 4.
6, 8, 10 or 20. Using the RangeValidator control, it only accepts the min and
max value. Is there any other control or property to do it?

For this type of validation there is no built in control. You need to
write a custom validator [1].
