Trigger event on variable change

Hi All


I have an app connected to a SQL db with Azure

Everything runs quick in the web UI. But it's a tad slower on the phone


The only place this causes a real problem is on the success screen

Because the BrowseGallery.Selected.... variables take so long to update (a good 10 seconds) initially the SuccessScreen still displays the PO number of the last PO raised. Likewise if you press the 'Book Now' button it launches an email with all the previous PO's details

I need to disable the 'Book Now' button and hide the label that contains the PO number until the variables have updated


Is there anyway of triggering events when the BrowseGallery variable updates?

Thanks all,
