OnLookup - SetFilter and regex?

(0) ShareShare
ReportReport
Posted on by SammySevens 132

Hi all,

I am able to filter a field on a specific page to only include relevant results. 

However, I would like to implement a RegEx (or some method) so that I filter results once, and then filter again for results that start with 3 letters (E.g. ABC , DEF, CAT)

Any thoughts?

I have the same question (0)

    Hi, are these three letters fixed?

    If so it's relatively simple.

    For example, you can use following ABC* to represent data beginning with ABC.

    Item.SETFILTER("No.",'ABC*');

     

    Hope this can give you some hints.

    Thanks.

    Hi Zhu,

    I feel privileged to get an answer from you! I read your posts all the time!

    Unfortunately the letters are not fixed, what I'd like is to filter out anything that begins with 3 alphabetical letters ([a-z])

    Hi, In that case, you can try to extract the first three characters, and then use a loop to determine whether they are all alphabetical letters.

    The following is an example of judging whether it is a number, I think it can be used as a reference.

    Hope this helps.

    Thanks.
