Hi,
I'm creating an ASP.NET application that needs to get data from database (time consuming) and show some indication (e.g. gif animation) that the application is doing something. After that the data should be send to user that the user can save or open the CSV file.
I'm able to do this with two button click's. One for getting the data from the database in codebehind and using javascript to show the gif animation for user in the meanwhile. Second to use the response.write(myData) and response.end() to send the data for user to save in CSV file.
The problem is that I need to do this with one button click. If I combine the code to one button click handler the data is sent correctly but the gif animation is not hidden because the page is not updated. How to do this correctly with one button click?
Thanks, Nitos
