Please elaborate more on your requirements, such as:

- Do you need that the text should not start with "Enter One" OR
- It should not end with "Enter One" OR
- It should not come anywhere within written text. OR
- It should not be specific as "Enter One"

try this "[^Enter One]"

This would accept all text which gets started with "Enter One".

^ sign denotes the start of the text.

Get real. In this context ^ indicates regex Class negation. "[^Enter One]" Class will match any single symbol except capital E, lower case n, etc...
As such, it can not possibly work for janaki problem. Standard regex mechanism to do such things is negative look-ahead assertion.
Problem is, TS does not honor this syntax outside of Perl. So, either

a) code something like "^([^E]|E[^n]|En[^t]|Ent[^e]...)" regex or

b) double-check item's value with FormAPI onSave using JS

It should not be specific as "Enter One" i.e not equals to "Enter One" is the requirement.

If I were faced with this requirement, I'd look at using FormAPI rather than the validation-regex in the DCR. You should be able to do your check more easily with js string comparison and then use IWItem.isValid(true|false) depending on the result of your comparison. IIRC, FormAPI is now the recommended method for form validation.

I suggest to use, custom script rather than finding a solution within validation-regex.

Hi ,this can be done through javascript very easily but the thing is i need the teamsite validation(validation-regex).

I tried thie folowing one,

Enter One

But that fails for some conditions like

Enter Oneee
Enter Onen
Enter Onetr

What would be the exact regular expression ?

<text size="60" maxlength="150" validation-regex = "[^(Enter One)]">
<default>Enter One
</text>

Enter Oneee

Enter Onetr

I beleive I've already explained why this could not possibly work.

For example, this validation will accept "three" or "Tree" but reject "tree" and "One". I also showed the idea of how to code
this sort of validation regex correctly - it'll be a long one
