I read your article regarding Using ASP.NET to Prompt a User to Save When Leaving a Page from a website, I downloaded the code there and used it in one of my application. But i have a problem with this, the method is working fine, but a datepicker when clicked the confirm msgbox is comming up.anyway i need to display this when i am about to leave the page without saving. Four check boxes i am using in this page, which the autopost back is set to true, to uncheck the 3 when one among four is selected. I understood that, this code doesn&#039;t work for a control, where the autopostback property is set to true.<BR>How I can handle controls with autopostback enabled using ur logic.Please suggest a solution<BR>
