Offline web app asp.net help

munkee

Hi all,

I have a website written in asp.net using vb.net. It is used to submit issue reports across our business. We are going to be using iPads in the near future and I have found that we often work in remote locations without Internet access in the field.

I have done some research and found I can firstly use HTML 5 Application cache to store my web app offline. I am now however at the point of wanting to understand how or even find out if it is possible to store user form submissions within a cache or local db on the iPad and then submit these once an Internet connection is available.

Any input into this is appreciated.

Thanks,
Chris

Seems I totally misunderstood the fundamental problem here. By building my app in asp.net/vb.net and utilising server side controls the app would never be able to be made offline in simple terms without a re-write. If the application is running offline the server side controls would not be able to work due to a lack of postback. This can not even be simulated within an offline app that uses these controls.

In order to produce a solution to this problem I am looking towards a full client side web application which can then work offline without a problem. Current languages such as html5 can allow for client side databases/local caches and a full download of all scripts to the clients browser. So far I do not know too much about javascript (other than the very basics) but I assume Jquery and ajax will allow me to create a pretty fake/native app which can submit to my sql server when I am online, whilst saving to local db when offline.

I'll post back with some references to the above as there seems to be a ton of information out there if you google "offline web app" "html5 local cache"
