Pages overview

In Dynamics 365 Business Central, pages are the main way to display and organize data. Pages are the primary object that a user will interact with and have a different behavior based on the type of page that you choose. Pages are designed independently of the device they are to be rendered on, and in this way the same page can be reused across phone, tablet, and web clients.

A page is defined in code as an object composed of controls, properties, actions, and triggers. You can also use Designer in Dynamics 365 Business Central to create a page. For more information, see Use Designer.

Whether you are creating a new page, or extending an existing page, you will add a new .al file to your project and describe the page object in code. The difference is basically that for a new page, you need to define the entire page, whereas when modifying an existing page, you only add the extra functionality or modify the existing.

The structure of a page is hierarchical and breaks down in to three sections. The first block contains metadata for the overall page. The metadata describes the page type and the source table it is showing data from. The next section; the layout, describes the visual parts on the page. The final section details the actions that are published on the page.

Furthermore, the page has properties. Properties work in the same way for pages as they do for other Dynamics 365 Business Central objects. For more information, see Page Properties.

Tip

For information about designing pages, see Page Types and Layouts.

Page metadata

For a new page object, you must at least specify the type of page; PageType and the data source; SourceTable of the page. And you can also set other metadata at the beginning of the declaration of the page object. IntelliSense can help you explore the options for, which metadata you can set. Press Ctrl+Space to activate IntelliSense from everywhere in your code.

page 50102 PageName
{
    PageType = List;
    SourceTable = TableName;
    Editable = true;
    ContextSensitiveHelpPage = 'feature-overview';
    ...
}

Types of pages

Which page type you choose depends on the application task that you want to support, the content that you want to display, and how you want to display it. The Role Center page is the main or home page and it helps the user focus on the most important daily tasks and activities. Other types of pages, such as list pages or card pages are typically linked from the home page for easy access.

Tip

For more information about the different page types and how their layouts supports user scenarios, see Page types and layouts.

The following page types are available:

Page type Use it for...
RoleCenter The Role Center page is the main home page for a role.
Card A Card page is used to view and edit one record or entity from a table.
CardPart A Card Part page is used in a FactBox on another page to view or edit additional fields associated with a selected entity in the page.
List A List page displays content from a table in a list format.
ListPart Similar to a List page, a List Part page displays content from a table in a list format. The difference is that you use the List part page as another page in a FactBox or as a part of the Role Center page.
ListPlus A ListPlus page displays content from a table in a list format. The difference from a List page is that the main content is a ListPart, not a Repeater group as the List has it.
Document A Document page usually consists of two separate pages combined into one, with one page nested in the other. A Document page is suitable for use when you want to display data from two tables that are linked together.
WorkSheet You use a Worksheet page type for creating worksheet or journal task pages.
ConfirmationDialog You use the ConfirmationDialog page to display messages or prompt users with a confirmation before they continue with the task that they are working on.
StandardDialog The StandardDialog is a simple page type that you use when users only need to input data and do not need to perform other actions from the page.
NavigatePage You use a Navigate page type to create an assisted setup guide, also known as a wizard, that leads the user through a sequence of steps for completing a task.
HeadlinePart You use a HeadlinePart page type to display a set of changing headlines on a Role Center.
API Pages of this type are used to generate web service endpoints and cannot be shown in the user interface. This page type should not be extended by creating a page extension object. Instead, create a new API by adding a page object.
PromptDialog Pages of this type are used to enable creating generative AI experiences with the copilot look and feel.

Note

For backwards compatibility we continue to support adding non-part pages as parts. We do, however, recommend that you redesign your page to only use Card part or List part, as we may remove support in a future update.

Page layout

The page layout of the page object determines what the page will look like and is specified in the layout section. The layout contains one or more area sections that define a certain placement on the page. The area sections available depend on the page type that you have chosen.

The following area categories are available depending on the page type:

Area type Placement on the page
Content The content area displays the content of, for example, a RoleCenter or a List page.
FactBoxes The FactBox area is placed to the right-most side of a page.
Displays content related to an item on the main content page.
RoleCenter The RoleCenter is the main page of the application and is used for quick access to frequently used information and tasks.
Prompt The prompt area is used to gather input from the user for a copilot interaction and used on pages of the type PromptDialog. For more information, see PromptDialog page type.

Page actions

All pages contain menu items and navigation controls called actions. In Dynamics 365 Business Central, actions are displayed at the top of each page in the ribbon or in the navigation pane. The actions section of the page describes what the user is able to do on a page and must be designed with the user's need for process support in mind.

Actions can be displayed in the ribbon of all pages and grouped together under the following actions tabs:

  • Home
  • Actions
  • Navigate
  • Report

Creating actions can include adding activity buttons/cues to a page, configuring navigation items on a user role center, or adding Reports to a page. To learn how you can enable users to quickly locate the actions they want to use, see Action overview.

Adding Help to the page objects

The Business Central user assistance model expects your solution to include tooltips and links to context-sensitive Help. For more information, see User Assistance Model.

Context-sensitive Help

To apply context-sensitive Help to your app, you specify a URL to your Help library in the app.json file, and you then set the relevant target Help files as property values for each of your page objects and page extension objects. Between them, these two settings then give users access to context-sensitive Help for the features in your app at runtime. For more information, see Configure Context-Sensitive Help.

Tooltips

In combination with descriptive captions and instructional text, tooltips are our current implementation of embedded user assistance, which is an important principle in today’s world of software design. The tooltips are there to help users unblock themselves by providing an answer to the most likely questions the users might have, such as “What data can I input here?” or “What is the data used for?”.

The base application has set the Tooltip property for all controls on (almost) all page objects. Most system actions also include tooltips so that users get a consistent experience. Your extensions are expected to also include tooltips for the same reason. For more information, see ToolTip Property.

Note

Starting in Business Central 2024 release wave 1, you can define tooltips on table fields. When a tooltip is defined on a table field, any page that uses the field automatically inherits the tooltip. For more information, see Add tooltips to table and page fields.

Instructional text

The base application has applied instructional text to setup guides, certain other types of page objects, and for page fields. Your extensions are expected to also include instructional text to setup guides for the same reason. Similarly, instructional text is useful to implement on page fields to describe example values or a short summary directly in the field, which guides the user for what to input in that field. For more information, see InstructionalText Property.

Example

The following example shows how you can apply user assistance and link to Help in a page object:

page 50101 "Reward Card"
{
    PageType = Card;
    SourceTable = Reward;
    ContextSensitiveHelpPage = 'sales-rewards';

    layout
    {
        area(content)
        {
            group(Reward)
            {
                InstructionalText = 'Fill in the fields so that you can reward customers with discounts.';
                field("Reward Id"; "Reward ID")
                {
                    ApplicationArea = All;
                    ToolTip = 'Specifies the unique ID of the reward.';
                }

                field(Description; Description)
                {
                    ApplicationArea = All;
                    ToolTip = 'Specifies what this type of reward is used for.';
                }

                field("Discount Percentage"; "Discount Percentage")
                {
                    ApplicationArea = All;
                    ToolTip = 'Specifies the impact of the reward on the customer''s price.';
                    InstructionalText = 'For example, 7.5 %';
                }
            }
        }
    }
}

In this example, the app.json file has specified a link to where the sales-rewards target file is published, such as "contextSensitiveHelpUrl": "https://mysite.com/documentation".

Best practices for designing pages

We recommend that you simplify the user experience by reducing what users see by default. You can promote the information that the users most frequently need to see and hide the less important information. For example:

  • Place common tasks in the ribbon

  • Organize information pages under FastTabs and, by default, hide the FastTabs that are infrequently visited.

  • Use one to three FactBoxes on a page to provide supplementary information and a place for adding notes

  • Add a target Help file for context-sensitive Help for the feature that the page object supports
