hi if you want the user to only enter numerals then you will habe to write your own control derving from textbox which only accepts number and the letters you want and will probably need clientside javascript code to prevent entering of other letters. there are free controls you can use. goto http://www.eworldui.net/[^] and you will find a numericbox cotrol that u can use, hope this helps signature ;P

If you only want to validate the input eg "12", "12.32", "128.25", etc, etc... You can use the Range validator, and set the Type to "Currency" and the operator to "DataTypeCheck"
