Timer control in gallery

[PapithaSekar1]

I want to use a timer control in gallery ,can someone help me to clear my doubt

1.I have 'check in time' field in a gallery, consider this field to start the timer and timer has to run for 20 minutes and turn the toggle button false.

Each record will have different time.

2.whenever ppl check in gallery needs to be updated automatically

For example: Check in time is 4:15 then from 4:15 timer has to run for 20 minutes til 4:35

Can someone help me to achieve this

Add your timer into the Gallery (let's say it is called Timer1).

On the Timer1 control, set the Duration to 1200000 (20 minutes)

On the Toggle, set the Default to !(Timer1.Value = Timer1.Duration)

I hope this is helpful for you.
