InfoPath Dev

 I need to have a confirmation pop up on an infopath form to reduce the chance of accidental deletes.

I am using infopath designer 2013 and have tried using

if (XdConfirmChoice.xdNo == thisXDocument.UI.Confirm("Message that should be shown to user", XdConfirmButtons.xdYesNo))

but it won't recognise thisXDocument.

Can  anyone help please ?

Just so you know I never found a solution to this, if I do I will come back and edit this.

In the end I just made a section that had a confirm and cancel button and just hid/showed that as appropriate and ran the code on button click of these.

Thanks anyway

Jacqui.
