I want a .aspx that will display the progress of a long web processing .. ? You can make it simple like the following for loop.
for (int i=0; i < 1000; i++)
? ? ? wait(1000);
? ? ? //Here the progress need to be displayed in a modal popup, containing like "Processing Item:abcde, record xxx of nnnn, Error: yy, Success: zzz"
In the modal, there should be a "Cancel" button, when cancel is clicked, then process should stop? displaying? "Cancelled By User" in the modal.
