PowerApps Host control
In Microsoft PowerApps, you can manage organizational data by running an app that you created, or an app that someone else created and shared with you. Apps run on mobile devices such as phones, or you can run them in a browser by starting Microsoft Dynamics 365 for Finance and Operations. You can create many types of apps without having to learn a programming language such as C#. By using the PowerApps Host control that is available to developers who use Microsoft Visual Studio, you can embed a PowerApps app that you’ve created or a shared PowerApps app. To learn more about PowerApps, see https://powerapps.microsoft.com.
Host a PowerApps app on a page
In PowerApps, find the web-based PowerApps app that you want to host, and record or copy the App ID value.
In Visual Studio, open your project, and then, in the form designer, add an instance of a PowerApps Host control to your page.
In the Properties pane, enter the App ID value.
If your PowerApps app shares or is linked to the current data source on your page, you should pass the ID of the primary or linked key field for the data that you want your PowerApps app to show. In this case, provide the ID as the value of the Entity ID, Entity ID Data Source/Field, or DataMethod property. This value will then be passed to your PowerApps app as a parm value, and your PowerApps app must use that value to obtain the linked data.
In some cases, your PowerApps app might be hosted in a development or sandbox PowerApps environment that is provided by Microsoft. In this case, you must supply that override URL as the value of the PowerApps Environment Override property.
Sizing is determined by the container that you put your control in. If you put your control in a form pattern that has limited available space, and your PowerApps app has been designed to be larger than the available space, your PowerApps app will have scroll bars.
