    Number Validation

    I have a text filed and on submitting the field I just want to check to ensure it is a number.

    Either floating point or integer.

    "12.9", "10000"

    Hmmmmm

    I'm and idiot, I know.

    Use a CompareValidator.
    Set the Operator property to DataTypeCheck
    Set the type to whatever you need, probably double or currency.

    Or you could use the IsNumeric function, but Hellswraith's way saves a trip to the server, by doing it client-side.
