I want to put coutdown timer on my site for displaying remaining time for cases. I am using gridview to display cases and i want to add these countdown timers seperate for every row. Please tell me how can i make countdown timer to show remaining time for every case and how can i display in gridview. I have stored target datetimes in ms sql database table. So i want to calculate remaining time in hours, minutes, seconds and display them.

Thank you in advance.

first if you put lot of timer controls in a form, it may impact performance

it is better to gor JavaScript client side control, and trigger the server side event when you required
