Hi Nisa,

You need to use "count" request parameter for your "list/query" service.

More info here: https://devcenter.appery.io/documenta...

Here is a common steps to populate label with count rows in db, you can also use here "where" request parameter for narrow items:

Open your list service.
Add "where" and "count" request parameters. http://prntscr.com/51gys0/direct
Navigate to "Test" tab and click "Test". You will get result of all item counts.
Click "Import as response". http://prntscr.com/51gzdz/direct
Navigate to "response" tab and check if you have parameters like on screen shot: http://prntscr.com/51h078/direct
Add this service to the page.
Open "Success" mapping for this service. And create link from "count" to label component you need. http://prntscr.com/51h23q/direct
Now you need to invoke this service datasource by event you wish. For example on "page load" or "button click" etc...

Regards.

thank you,this is very useful but i need to know
what if i don't want to display it?
for example the parents can register their kids after they has login,so i want to use the value from count is for if the user has register for their kids more than 3 times ( the kids register in another page)
i already follow the step and i found i dont have any label cause i don't want to display it
