Refresh Gallery in Power App that interacts with Power Automate flow

Hello,

I have the following gallery based on a Sharepoint List in my Power App that activates a Power Automate flow from a button:

Quite early in the flow I set the column ReleaseRequest to Yes in the Sharepoint List. I was hoping to update the button behaviour based on column:

Text property of button:

If(ThisItem.ReleaseRequest = "Yes", "Requested", "Request")

DisplayMode property:

If(ThisItem.ReleaseRequest = "Yes", DisplayMode.Disabled, DisplayMode.Edit)

I try to refresh my DataSource after 5 seconds after running the Power automate Workflow in hopes that the gallery will refresh real time and the button will update. The OnSelect of the Request button has:

OtherUser_Cancellation_DNG_PowerApp.Run(requestedOtherDocRef, User().Email);
Set(varStartTimer, true);

And the invisible timer element has OnTimerEnd after being Started with the varStartTimer set to true:

Set(varStartTimer, false);
Refresh('Authorization Matrix');

However the gallery still does not refresh real time. Is there any other way to achieve this?

@DJanssen What is 'Authorization Matrix'? Is it data source? Did you tried resetting the gallery control itself?

Reset( GalleryName)

@ANB Yes the 'Authorization Matrix' is the data source! Thanks I will try your suggestion by adding the Reset to my Timer property.

So I tried the following on the OnTimerEnd property:

Set(varStartTimer, false); Refresh('Authorization Matrix'); Reset('CancelDoc_OtherUsersGallery');

The Authorization Matrix is the Data Source and the CancelDoc_OhterUserGallery the gallery control itself. It did not work unfortunately. I checked the flow run time and when the ReleaseReqest is set to Yes this takes less than 1 second, so the 5 seconds timer should be enough.

I published the app to try it out when not in Play Design mode. But the gallery does not seem to refresh real time. When I navigate back and forward the button has changed but I prefer to have this update realtime.

@DJanssen Is there any output parameter that you are using for Power Automate?

OtherUser_Cancellation_DNG_PowerApp.Run(requestedOtherDocRef, User().Email)

If not then as a suggestion, i would ask you if you can set output parameter to Power Automate: Example:

Get the ReleaseRequest information in this output parameter.

Then use this parameter in Power using this:

Set(gblvar_Output, OtherUser_Cancellation_DNG_PowerApp.Run(requestedOtherDocRef, User().Email).output)

Then use this gblvar_Output for the for text and display mode of control.

Hey @ANB ,

I don't think I can use this in my case as the Power automate flow starts an Approval process which can take quite long to complete:
So in order for the flow to be done and return the output this could possibly take hours or days.

@DJanssen Then Refresh of Data source should work in this case. Do this for Timer control:

OnTimerStart have below code:

Refresh('Authorization Matrix');

With this every 5 second the source will refresh. No need to reset gallery. No need to use varStartTimer.

@ANB This worked! A bit puzzled why my initial approach did not work by refreshing it after 5 seconds with the OnTimerEnd property but happy to see the behaviour I need 🙂 The items now flicker every 5 seconds so I'm hoping my client will not complain about this.
