Hi All,

I have a situation where I need to remove the last file attached from the attachment control, if a condition returns true.

i.e.:

OnAddFile Event - > if(true,"Remove last file attached from attachment control")

Please guide.

Hi @Anonymous ,

Maybe you could try to select the Attachments Data Card and apply the following formula on its Update property as:
If(conditionresult=true&&CountRows(DataCardValue31.Attachments)>1,FirstN(DataCardValue31.Attachments,Sum(CountRows(DataCardValue31.Attachments),-1)),DataCardValue31.Attachments)
When updating attachments and the number of attachments is greater than 1, this formula will not upload the last attachment to the data source.

Best Regards,
Charlie Choi
