I get the following error
"Timeout expired. the timeout period elapsed prior to obtaining a connection from the pool. this may have occurred because all pooled connections were in use and max pool size was reached."
The below code is in the click event of the Upload button. This works fine when it is executed the first time (for loop, loops thru around 100 records). However, when I click the button the second time, it displays the above error after looping around 6 to 8 times.
As far as I know, I am closing the connection.
What am I doing wrong?
Please help
