Posted on by Community Power Pla... Microsoft Employee

I have Lat/Long data on my Powerapp page which is want to continously send to Shareponit list after every 5 min.

I have made the logic and share point list but data is written in share point only 1 time and i need to refresh the page manually or go to another page and come back to this page.

OnVisible Property of Page:

Patch(Testpowerapp,
{
Title: Office365Users.MyProfile().DisplayName,
Lat: Lat.Text,
Long: Long.Text
}

)

Not sure doing it every 5 minutes is a good idea, but to do something like this create a Flow with a recurrence trigger set to the time interval. Then in the Flow update the listitem. Otherwise you could just use a timer in the PowerApps page and set it to autostart and update the list using OnTimerEnd.

Hi @Pstork1 , Thanks for your reply.
I have If conditions that if the loction is OUT or IN a given Lat/Long range then, it should update the Sharepoint list.

Set(_flag1,Status.Text);
If(_flag1<>_flag,
Concurrent(Patch(Testpowerapp,
{
Title: Office365Users.MyProfile().DisplayName,
DT: Now() + .0835,
Status: Status.Text
}
) , Set(_flag,_flag1) ) )

Can a timer be used to check IN or OUT lable.text in the page?

Two things I see wrong here.

1) Why are you using Concurrent()? YOu only have one function so why do you need Concurrent?

2) Your Patch statement won't work because you don't identify the record you want to update. The syntax for Patch should be Patch(datasource, record to be updated in deatasource, updates). You have Patch(datasource, updates)

1) you don't need to update the Flag at the same time as the patch. Doing it immediately after the patch should work exactly the same.

2) If you want to create a new record you need to supply defaults(datasource) as the second parameter. YOu use defaults for a new record and an existing record for an update. YOu don't supply either.

Hi @Anonymous ,

1)Yes, Timer control's OnTimeEnd can be used to set variable.

2)Your three actions are step by step. You do not need to use Concurrent function. Concurrent function is used to act two actions at the same time. Just use ";", which means that act actions in order.

3)The right syntax of Patch should be:

Patch(tablename, Defaults( tablename),{....}) //create a new item

Patch(tablename,one spefic item, {....}) //modify an existing item, please replace one spefic item with the item that you want to modify

Here's a doc about Patch for your reference:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-patch

To sum up, try this formula:

Set(_flag1,Status.Text); If(_flag1<>_flag, Patch(Testpowerapp,Defaults(Testpowerapp), { Title: Office365Users.MyProfile().DisplayName, DT: Now() + .0835, Status: Status.Text } ) ;
Set(_flag,_flag1)
