Possibility of Case specific Form??


Dear Experts,

If I need to create a lowercase specific field form in which special charaters are not allowed. Please suggest if this is possible in Episerver CMS.

If yes, via Editor studio or via code level changes?

Thanks in Advanced

You can add a regular expression in a textbox field in Episerver Forms. So just create the pattern you want that only support lowercase without characters and add it in there as shown below

Thanks for the URL's Scott, I am checking them if I can get something.

Something like this?

^[a-z ]*$

And if you don't want to allow space:

I think its working correctly with above suggested pattern and allowing only small charater not capital.

But something wrong with special charater format, Above suggested one also works for special charaters? As I need to get Special characters skip in same field also.

Thanks in advanced.

I'm not sure I understand your question.
The above regex will only allow ASCII characters in the range from a to z.
Could you post some screenshots which show things that are not working correctly and the expected result? Thanks

Hello Dejan,

I checked to post error screen shot, it looks to be issue related with some partner company association mandate for me or else i can't post the images.

But anyways, What I mean is, With suggest expression it is working fine for small/lower case entries condition but regarding Non allowance of special characters, Is it possible that expression also to include in this? or will that go into a separate one.

Actually I need a field which should not allow special characters and should only allow lower case letters.

That regular expression doesn't allow special characters. If you want to allow special characters, simply add them inside square brackets.

For example, this regular expression allows lowercase characters from a - z, exclamation mark, and a dollar sign, but no other special characters like dot, question mark, etc:


Hope this helps!

Dear Dejan,
Thanks for your help on this last time. Just addition to that if you can help to understand.

Is it possible to generate a Form number? does the form have a id counter or anything like that? if yes, is possible to send this number with the solicitation?
