Solved: Re: Embedding a Canvas App in a Model Driven App -... - Page 2

I've created a canvas app and (mostly) successfully embedded it into a tab in a model-driven app. However, there are two issues... First, there is a large dark-gray space above and below the tablet-sized app. I'm not sure why it's there, and as the canvas app is embedded in the first field in the tab, the first gray block is even more confusing. (Attached "Gray space.jpg" image)

The bigger problem is that my app simply reads "Getting your data..." and never updates. It's in the same environment, the data is loaded via an "Edit" form, and is linked to the proper entity. There are no errors listed for the app, and in the Studio, everything works perfectly. (Attached "GettingYourData.jpg" and "PAStudio.jpg" images)

The app fields pull/post data from grant application records in the CDS. All of the pages in the app load, and the built-in navigation works. It's just that no data ever loads.

Does anyone have any ideas what could be causing this? What better information can I provide to help diagnose this issue?

Thanks!

We need to take a few steps back and start from the beginning. How did you start the process of embedding a canvas app in a model-driven app?

Did you choose a mandatory field on a model-driven form? Did you add the Power Appd control to that field? Tablet and Phone options are disabled by default. You can only select Erb which is you need to select as it is not selected by default. Then when you click on what I believe is called Customize, it opens the Power Apps studio with the ModelDrivenFormIntegration control added to the app so you can fetch the contextual record. My blog post here talks about the entire process from the beginning. https://thepoweraddict.com/how-to-embed-a-canvas-app-in-a-model-driven-form/

Let's review these steps first. And don't worry about your existing app, we will not let it go waste. Let me know if you want to get on a call/screen share session.

Thanks Hardit,

I did choose a mandatory field, but where I think that I went wrong is creating the app from make.powerapps.com, as opposed to creating it from inside the form itself. I think that because the only options available to me were phone and tablet. I did see the "Customize" button that you're talking about, but since I'd already created the app outside of the form, I simply copied/pasted the app ID into the field.

Let me create the form from inside the field and see how that works. Then, if need be, I can chalk this up to a timely learning experience! And if this doesn't work, I'll certainly take you up on that Teams call!

Thanks again!

I was able to successfully embed the canvas app into the MDA, and now I'm seeing what you were referring to with the ModelDrivenFormIntegration.Item" property - and also why mine wasn't working. It does seem that there's a way that I could have retrofitted my old app into this by installing that ModelDrivenFormIntegration object, but that's a course for another day!

Thanks so much for your help - I'm going to mark your blogs as the accepted solution! Very much appreciated!
