Change Powerapps label by Flow

[KollinFreise]

Hello,
I want to change a label by calling a Flow.
I created a flow which returns a string.
Now I want to use this flow to change the label of a PowerApps custom formula.
But I am not able to call the flow on this way...
Did you know any other possibilities to change the label text by the return value of a flow?

Thanks a lot for your help

Hi @KollinFreise ,

Based on the issue that you mentioned, I think there is something wrong with your operation.

The 'FlowName'.Run() formula is a Bahaviour function, which could only be executed within Behaviour Property, e.g. OnSelect property of a Button, the OnVisible property of a screen, OnStart property of App control, ... etc.

As an alternative solution, you could consider put your 'FlowName'.Run() formula within the OnStart property of the App control or OnVisible property of current screen, then save the returned result into a variable, then set the Text property of the Label to this variable. So when your app loads or your current screen is visible, the Label control would be populated with proper value returned from your flow.

I have made a test on my side, please take a try with the following workaround:

Set the OnVisible property of your current screen which contains the Label control or the OnStart property of the App control to following:

Set(
       ReturnedResult,
       PowerAppsbutton.Run("VE,VD", 0).returnedproperty
)

Note: The returnedproperty represents the property you specified in the "Response to PowerApps" action, which you want to return from your flow to your app.

If you use "Request - Reponse" action to return value from your flow to your app, please modify above formula as below:

Set(
       ReturnedResult,
       PowerAppsbutton.Run("VE,VD", 0)
)

Then set the Text property of the Label control to following:

ReturnedResult

Please take a try with above solution, then re-load your app, check if the issue is solved.

Best regards,
