Help with Hiding a Button based on # of attachments

(0) ShareShare
ReportReport
Posted on by 30

Hello,

 

I have an app that acts as a way to complete a form with various screens that attach a signature to a sharepoint list item via an attachment.

 

I would like to somehow make the "sign/save form" button not visible if the item already has two attachments (basically two signatures). 

 

Is there any sort of "If" statement I can implement on a visibility control that will make a button not visible if the item being viewed on the form has 2 or more attachments?

    You will need to reference the attachments table of the record you are working on.

    With that you can set the Visible property of the button to:

    CountRows(yourRecord.Attachments) < 2

     

    I hope this is helpful for you.

    Awesome @RandyHayes . That does seem to work. I have one follow up question I wonder if you may be able to help me with.

     

    In another part of my form I have a section that I would like to display specific attachments. I have found and am using the "first(thisitem.attachments).value" to display the first attachment/signature.

     

    Is there a way to specifically display the second?

     

    I tried "second(thisitem.attachments).value" but it seems to affect a function to do with time rather than the second item in my attachment list.

    There is no Second function.  You can get the second record with this:

    Last(FirstN(thisitem.attachments, 2)).value

    Understood - looks like I can use that to select any specific item in the list with a little tweaking. Very appreciated. 😁

    @SamR 

    Yes, as you can see the number 2 in that formula "essentially" determines which record you are going to get.
