Counting Attachments to enable a button

Hi everyone,

I need to enable a button based on the count of attachments. If the attachment datacard is not in a form it works but I can't get the value from the datacard property when it's in the form. I'm using countrows - is there another way to achieve this?

This is seriously irritating. Is there any way to add an attachment to a list without a form?

For what it's worth, you can't access a variable from inside the form either. I tried to update a counter when adding an attachment and nothing happens. It just stays at its initialised value.

Interesting. Just created a new project just incase there was something quirky in my current app but no change. Tried a different user - no change. Just have to wait I guess.
Where did you set the variable?

Just spoke to microsoft support, the FormMode must be New in order to access values in the form. I was testing my progress in Edit mode. I didn't realise the different modes would have that effect.

Hi @DSFlemming ,

That does not really help the bug - it makes it worse. There are always needs to access form information in both Edit and View modes.

Agreed. It solves my issue but it's still going to be a problem.

That's awesome...and a better workaround than using OnChange (which didn't work with a person lookup).
Seems to work when editing an existing record by doing NewForm(), getting the record, then EditForm()...or, even easier, just set the form's DefaultMode property to FormMode.New.

I just received an email from Microsoft regarding my issue. They're still working on it....
You saved the day! Maybe this will help them. 😉
