Asp.net realtime update progress

[Vis1/0N]

I have a old Asp.net 2.0 site that needs a small update. A simple task is now being done in a batch, therefore server side processing from O(1) will change to (O)n with n being up to 2000+ ( 120 seconds in )

Without major redevelopment using more modern tech how could I give a real time update on the progress? When the button in the update panel is clicked then the selected items are posted back and processed. I can have a busy dialog but that is no indicator of progress. The other solutions I can come up with will require some work therefore looking for any quick pointers first.

Maybe look at adding a jquery async progress updater. It can be updated via a call from the server.

Or if you want to really go old school ( not recommended ) , have a control that shows progress ( based on whatever logic you have ) and a timer on the page that forces a post back at a time interval of your choice. Not ideal though, especially in a modern world. I'd investigate the jquery control route first.

without major redevelopment? mmmmm... F5 is just easier and less complicated bro

Is real-time actual progress actually needed? What about fake halving progress bar? Every N units of time, progress the bar 50% of the remaining time, until the ajax promise resolves or rejects

websocket and little bit of javascript. easy to retrofit

Considering that that IE7 support was removed and IE10+ approved recently I have been limited to bug fixes and small features.

I think what I will do is if the bulk operation is in place and expected to take more than 10 seconds I will redirect to a page that does the processing in chunks and display a button to carry on processing the next 200 loops but with a Response.AddHeader("Refresh", "3") to allow the page to postback automatically. Not much to do then.

Wait..... you only got the approval to upgrade to IE10... recently? IE7 support ended in January 2016
