Question

I have a web application that allows a user to upload an Excel spreadsheet to insert ~250,000 records at a time into a database. I’d like to have a progress bar that shows the user how far along the process is.

Here’s my basic plan

1. Upload a spreadsheet
2. Write total ExcelRow Count to TempTable
3. Loop through cells in each row to build sql and execute query (for each row)
4. Client makes ajax call every 3 seconds to get Count(*) From TempTable Group By ExcelRowID
5. Update progress bar until 100%

Is there a better way of doing this? Is there anything I should watch out for? Will this work?

I’m using ASP.Net 4.0, SQL Server 2008 R2 Express, EPPlus 3.0, and jQuery 1.7.1

Answer 1

I ended up just approximating the time and making a very elaborate progressbar to entertain the user.
