In most modern apps, it’s common to need to set a default choice in a dropdown menu. But how can you do this in Power Apps/Dynamics 365? The answer is different whether you’re building a Model-driven app or a Canvas app.
In this hands-on tutorial, I’ll show you my simple datasource setup in Dataverse, and then how you can easily set the default choice if you’re using a Model-driven app. For a Canvas app, we’ll need to do a little bit more work, but I’ll show you two options to make it happen.
If you want to learn more about Power Apps Canvas Apps, I’ve partnered with the good folks at Pluralsight to do a 3-hour course. During the course, we’ll build an app from scratch, leveraging data from Dataverse. Check it out! https://pluralsight.pxf.io/LP12Jo
