Power Apps - part 2

Forms and Galleries

• A form is used to view, edit, and create a single row for a data source.
• To configure a form, you select its data source.
• A gallery displays a list of rows from a data source.
• To configure a gallery control, you select its data source.

Buttons and Screens

• A button has a formula that can change the properties of other controls.
• A button can cause data to be saved, but the button is not linked to a data source.
• A screen is not linked to a data source.
• The controls added to the screen can be linked to data sources.

Model-Driven Applications

• Model-driven applications are used to create backend applications connected to Dataverse.
• They are typically used by management and other employees and can include business process flows for providing guidance to employees.
• Model-driven app forms are linked to a Microsoft Dataverse table.
• A form displays a subset of the columns for that table.
• To enable a different group of users to edit different fields, a new form should be created.
• A Microsoft Dataverse table can have multiple forms containing different columns from the table and different layouts.
• The app designer can select which of the forms is available in the app.

Business Process Flows and Views

• Business process flows are associated with a Microsoft Dataverse table, not the forms for the table.
• A view displays columns from the table but as a list.
• A form is required to edit the data.
• The view designer allows you to select the columns from the table to be shown and define the filter criteria for the rows to be shown in the view.
• The view designer also allows you to specify the sorting behavior of the rows in the view.
• The app designer determines which view is included in the app, not the view designer.
• All views can be filtered by the user in a model-driven app.

Canvas Applications and Power Pages

• Canvas applications are used to create applications targeted at specific scenarios.
• Desktop flows are used to create robotic process automations that automate manual tasks typically done by end users.
• Power Pages sites provide external users access to Dataverse data.
• They use model-driven application forms and views to display information to external users.

Microsoft Dataverse and Teams

• Microsoft Dataverse is a data platform.
• Power Apps created in Microsoft Dataverse for Teams are automatically shared with all the members of the Microsoft 365 group to which the Team is associated.
• This solution requires Microsoft Dataverse for Teams to satisfy the requirements.
• While multiple environments can be used with Microsoft Dataverse, only one environment can exist when using Microsoft Dataverse for Teams.
• Additionally, apps created in other environments are not automatically shared with all the users the way they are when created in a Microsoft Dataverse for Teams environment.

Sharing and Publishing

• A canvas app must be published before it can be shared.
• When a canvas app is connected to a Microsoft Dataverse table, a security role must be assigned.
• The email is only a notification; it does not affect sharing capabilities.
• To share an app, it is not required to allow users to edit it.
• Canvas apps can use data from different sources, including Azure SQL databases.
• Model-driven apps and canvas apps use data coming from Microsoft Dataverse, not Azure SQL databases.
