Model Driven Apps - Event Trigger help "OnChange"

Hi All,

I am a couple weeks old in Model Driven apps using the CDS/Dataverse but learning quickly. I have a "Country" field and a "State/Province" field. I am trying to reset the "Province/State" field if the country field is changed.


I know this should be an "OnChange" event I am just not sure how this works and do not have any JS coding background. Can anyone direct me on how I can do this now and with future fields please?

HI @mykedeabreu ,

On the OnChange of the Control control just put


meaning the actual input control (not the data card)

That would work in Canvas. I am asking for a Model Driven App.

@mykedeabreu ,

I will tag @RandyHayes here - I do not use Model Driven.

Hi Mykedeabreu,


Did you ever found a solution for this, I'm facing the same problems.
