Hi ppl,

What are the recommended field validations for validating user input?
I know the question is broad... Looking for a starting list. Things like, sql injection, removing funny characters (not people) etc...

I understand the basic checks just want to know if there is a good list out there of things to watch out for.

Thanks
Ash

You can add few basic validation methods to your UI control.

ValueMissing - returns true if a required element is empty.
TypeMismatch - This value applies to all the new type attributes. For example, if an email value is incorrect, this attribute returns true.
PatternMismatch - When an element contains the pattern attribute and doesn’t conform to the regular expression conditions, this attribute will return true.
TooLong - When any element surpasses its maxlength property this attribute will return true.
Rangeflow - If an element’s min or max attributes are above or below the specified values, this attribute will return true.
StepMismatch- When an element with the step attribute doesn’t conform to the required step value, this attribute returns true.
Valid - If any of the values listed above return true, this attribute returns false to indicate the field is invalid. Otherwise, if all the conditions
