2.  FilteredTextBox is an extender which prevents a user from entering invalid characters into a text box. Note that since this effect can be avoided by deactivating JavaScript, you should use this extender as a convenience for your users, but you must never expect that the data being sent to the server consists of "valid" chars only.

3.  TargetControlID - The ID of the text box for this extender to operate on  FilterType - A the type of filter to apply, as a comma-separated combination of :  Numbers.  LowercaseLetters.  UppercaseLetters  Custom,If Custom is specified, the ValidChars field will be used in addition to other settings such as Numbers.  FilterMode - A the filter mode to apply, either ValidChars (default) or InvalidChars. If set to InvalidChars, FilterType must be set to Custom; if set to ValidChars, FilterType must contain Custom.  ValidChars - A string consisting of all characters considered valid for the text field, if "Custom" is specified as the filter type. Otherwise this parameter is ignored.  InvalidChars - A string consisting of all characters considered invalid for the text field, if "Custom" is specified as the filter type and "InvalidChars" as the filter mode. Otherwise this parameter is ignored.  FilterInterval - An integer containing the interval (in milliseconds) in which the field's contents are filtered, defaults to 250.
