Hey Guys

I have a SharePoint list where i manage all of the companies IT Support requests from

I have created and published a Canvas app that allows users to submit a new support request on any device they have.

We have a few sites with patchy internet so would like to make the app avalible offline, so when they have internet again they have the ability to sync/submit the ticket.

I have found a few examples online on how to do this but none seem to fit my scenario.

Few screenshots below.

Any help would be great.

Cheers!

Adam

Yep, that is by design as a collection is only held in memory. You will want to use the SaveData/LoadData/ClearData functions to accomplish this.

I will be working on a project in the next few weeks that requires offline functionality so I will have more experience in this regard and will check back with more info as I learn how best to do this.

Thanks for the Reply Aaron.

Is there a way to get the collection data to save when the app is closed?
I have the below working to save the form in to a collection.
But when i close and reopen the app the data is missing?

Collect(
TicketCollection,
{
Requestor:RequestorValue,
ContactNumber:ContactNumberValue,
EmailAddress:EmailValue,
Subject:SubjectValue,
Description:DescriptionValue,
Status:StatusValue,
RequiredDate:RequiredDateValue,
Urgency:UrgencyValue,
Category:SelectedCategory,
SubCatApplication:ApplicationValue,
SubCatHardware:HardwareValue,
SubCatNetwork:NetworkValue,
SubCatUser:UserRelatedValue
}
);

Cheers

A potential design could be to save new records in a collection to submit to SharePoint later:

Create a collection that has the form schema you want to write to SharePoint.
Patch new support records to this collection.
Create an 'Upload' button, in OnSelect add a ForAll to loop through the collection and patch to SharePoint.
