PowerApp Custom PCF OnChange does not trigger.

How can I get the OnChange property to trigger.  Do I need to somehow register the  OnChange event?  If so, how?

    Hi @ra1449 , 

     

    From inside the PCF you need to call the notifyOutputChanges(). The runtime will call the PCF "getOutputs" method, where you can pass the new value(s).

    On the form you can use the control as any other one, and register to onChange events as usual.

     

    Maybe you would like to check the PCF architecture too, for more details: https://docs.microsoft.com/en-us/learn/modules/get-started-component-framework/2-architecture?WT.mc_id=BA-MVP-5004107

     

     

    Hope this helps!

     

    Kind regards,

    Diana
