Hi Team,

I need for loop in power apps but I don't see this. Is for loop available in PowerApps? Is forAll() replacement for For loop in PowerApps? Could you please share a sample code to build for loop in PowerApps.

I would like to have for loop to make concurrent calls to automate flow to get items by some batch of item IDs may be by specifying start, end and increment operator in the loop.

Hi @KrithiAnaje ,

You could create a timer control to do the loop.

Thank you. I want to auto-start the timer on page load itself (not on button click). I tried to set below code on OnVisible property of the screen, but still the loop execution starts after I click the timer instead of page load,
UpdateContext({varStartTimer: false});
UpdateContext({varRuns: 0});
UpdateContext({varStartTimer: true});

Hi @KrithiAnaje ,

You could set the timer's AutoStart property to true to auto-start the timer.

I have initialized UpdateContext({varRuns: 0}); in the OnVisible property of screen, but the loop is not working as expected. It must start with 0 and then increment by 1 but I get values like 26 in OnTimerEnd even though LoopEnd value is 5. The code If(varRuns > (varLoopEnd-1), UpdateContext({varTimerStart: false})); this is keep on running without stopping the timer.
