Validation - Regular Expression

Hi,

Yet another newbie question here. I am creating a new document type and as I am adding fields I would like to enforce certain rules to ensure data integrity. I see in the vaidation section for the field a place to enter a regular expression.

So for a real simple one for example the field cannot be left blank, would I enter: IS NOT NULL which is basically what I would do in Sql Server? Is there a listing anywhere of what regular expressions are available for validating fields as I have not been able to find on in any of the documentation?

Thanks

Gary

RE:Validation - Regular Expression

Hi,

When defining a new filed for the document type (or for bizform) there is a check box "Allow empty value" - when checked, the field could be left empty, if not checked, appropriate value is awaited for the field type.

In the validation fields you can use the standard .NET regular expressions. For example - http://regexlib.com/

Member	ndeych-gmail - 10/5/2009 10:09:02 AM RE:Validation - Regular Expression How can I specify a custom error message if the field is left empty but is required? Write now it just says "Please enter some value." I tried putting a message for each field under the validation section but it does not appear, seems like its only for the regex validation. Thanks


Kentico Developer	kentico_martind - 10/8/2009 7:24:42 AM RE:Validation - Regular Expression Hello, You can set following value into 'Min length' field in Validation section: 1 Then you can specify message that will be displayed if field is empty into 'Error message' field.
