Hi, In my web application when hiting the F5 the data is posted again and again. Button is a User Control and is been used many places, problem is with only one palce. The button is used to generate report, on clicking that the data will be posted to SQL to insert a record and a process is started to generate the records, in this mean time the page is responded back and ready. at this moment if the user uses the F% - Refresh button the data is again posting and an warning pop up is displayed. "To display the webpage again, Internet Explorer needs to resend the information you've previously Submitted. If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click retry to display the we page again." thanks in advance. -- Raghuram Raichooti
