Navigation actions that define no tooltip of their own inherit the page tooltip, as the version 29 client demo shows, while version 28 shows the action's own tooltip. The video covers less repeated code, table-field tooltips, consistent tooltips across the app, and why AI agents and MCP servers need meaningful tooltip text. tier: community language: en tags: - tooltip property - page design - al development - code reduction - action inheritance - ai agents - consistency - table fields - navigation actions - developer guidelines system: development review: state: reviewed by: opus at: "2026-10-07T23:18:55.004Z" flags: [] generated: at: "2026-10-09T00:29:02.995Z" pipeline: 0.2.0 prompts: extract-video: 1 summarize-video: 2 input_hash: 2f3e6fa89db6114ec1c7433005f9509a56f45f519cfb22461248666f89d11d8b evidence: - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=535s title: "ToolTip property on page objects: generally available" date: "2026-09-14T04:45:31.000Z" commit: null t: 535 quote: Tool tip and or tool tip ML are now available directly on business central page object. - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=20s title: "Business Central: ToolTip Property Now Available on Pages" date: "2026-09-14T04:45:31.000Z" commit: null t: 20 quote: you can now define tool tip or or and tooltip ML properties directly into the page object. - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=33s title: "Business Central: ToolTip Property Now Available on Pages" date: "2026-09-14T04:45:31.000Z" commit: null t: 33 quote: navigation action can inherit those tool tip when they don't define one themsel. - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=93s title: "Business Central: ToolTip Property Now Available on Pages" date: "2026-09-14T04:45:31.000Z" commit: null t: 93 quote: With this change Microsoft have made tool tip and tool tip ML available on the page object level as well. - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=376s title: "Business Central: ToolTip Property Now Available on Pages" date: "2026-09-14T04:45:31.000Z" commit: null t: 376 quote: You cannot do both because that generates an error message that you should either use a tool tip or a tool tip ML. - kind: video url: https://www.youtube.com/watch?v=Z0K38pXvjWk&t=407s title: "Business Central: ToolTip Property Now Available on Pages" date: "2026-09-14T04:45:31.000Z" commit: null t: 407 quote: AI uses these tool tips very seriously.

Before this, tooltips were defined repeatedly on individual actions. A tooltip set once on the page can now be reused wherever an action navigates to that page. It also covers defining tooltips on table fields so pages inherit them, which reduces page code size. The presenter stresses that AI agents and MCP servers rely on tooltips, so the text should be meaningful and not just generated static text. A client-side demo shows the inheritance. ## Key points - ToolTip and ToolTipML can be defined directly on a page object. - Using both ToolTip and ToolTipML on the same object generates an error; use one or the other. - A navigation action inherits the page tooltip only if the action defines no tooltip of its own. - An action can still override the page-level tooltip by defining its own. - Defining the tooltip once on the page keeps it consistent where the same page is referenced from several places in the application. - Tooltips defined on table fields can be inherited by page fields, which reduces page code. This is recommended but not mandatory. - AI agents and MCP servers use tooltips on pages, tables and fields, so write meaningful text instead of tool-generated placeholders. ## Chapters - [0:00](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=0s) Introduction to tooltip feature on pages - [0:57](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=57s) Understanding tooltips and context for users - [2:02](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=122s) Historical tooltip definition on pages - [3:17](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=197s) Reducing page size through action references and table-level tooltips - [4:56](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=296s) Page-level tooltips for consistency across the application - [6:27](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=387s) AI agents and meaningful tooltip content - [7:32](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=452s) Benefits and client-side demonstration - [8:34](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=514s) Key takeaways and action inheritance ## Features | Feature | Status | At | Evidence | |---|---|---|---| | ToolTip property on page objects | generally available | [0:20](https://www.youtube.com/watch?v=Z0K38pXvjWk&t=20s) | "Tool tip and or tool tip ML are now available directly on business central page object."
