Mein Blick auf SharePoint & M365 & .NET aus der Sicht eines Full-Stack Entwicklers

A blocked HTTP request does not have to stop your next SharePoint app. With a small Power Automate flow and a file in a SharePoint library, you can bring external information into an interactive HTML dashboard created with Copilot. In this video, I demonstrate the approach with a company news feed. The goal is to turn news from an external service into an attractive dashboard with headlines, dates, categories, and additional details on demand. The challenge: Copilot cannot connect the app directly to the endpoint My first idea was straightforward: give Copilot the endpoint details, describe the desired layout, and ask it to build the app. An HTTP endpoint is simply a web address through which a service provides data—in this case, company news. However, Copilot-generated HTML apps running in SharePoint's HTML page experience cannot call external HTTP endpoints directly. SharePoint runs these pages in a restricted sandbox and blocks outbound API calls. Provid...

Can Copilot build an HTML app that brings together two connected SharePoint lists? Yes—and this video demonstrates exactly that. Using a training catalogue and a participant registration list, I create an interactive app that helps employees explore training offers, view registered participants, and start their own registration. The key ingredient is a lookup column connecting the two lists . Copilot uses this relationship to bring the right information together in one interface. With the Smart HTML application page Integrator web part, the finished app becomes part of an existing SharePoint page. A practical example: Employee Training and Registration Many companies manage internal training in SharePoint. One list holds the available courses, while another records who has registered for each session. This is also the starting point for the demonstration. SharePoint list Purpose ...

A live message board, automatic updates, and interactive details—all created with Copilot without writing a single line of code. What if your next intranet improvement started with a simple description? In this video, I demonstrate how to build a custom notification and message board app with Copilot in under five minutes. Then I embed it into an existing SharePoint page using the Smart HTML application page Integrator web part. The result is a compact, interactive board that keeps company messages visible exactly where employees already work. HTML apps now feel at home in SharePoint SharePoint can now render raw HTML pages directly within the SharePoint chrome, without distracting document-preview controls. Here, “chrome” means the familiar SharePoint surroundings, such as the site header and navigation. Your HTML content becomes part of that experience, with the focus on the app itself. This opens up useful possibilities for custom dashboards, informati...

A support ticket changes status, and your dashboard updates a few seconds later—right inside your SharePoint page. In my latest video, I demonstrate how native HTML pages, Copilot, and the Smart HTML application page Integrator work together to make this possible. Raw HTML, seamlessly integrated into SharePoint SharePoint can now render raw HTML pages directly within the SharePoint chrome, without distracting file-preview controls. “Chrome” simply means the familiar SharePoint surroundings, such as the site header and navigation. Your HTML content appears within that environment, giving users a clean, focused experience. This makes HTML a useful option for dashboards, visual summaries, and small business applications. Users can open the content and stay within the SharePoint site they already know. HTML is now a fully supported page type in SharePoint’s Site Pages library. You can create or upload HTML pages, edit their content, publish them, and share th...

Große Bilder, überlappende Textflächen und eine Abteilungsseite mit eigenem Charakter: Mit flexiblen Abschnitten lässt sich in SharePoint viel gestalten. Drei neue Funktionen erleichtern jetzt die Arbeit daran: vorhandene Abschnitte umwandeln, das Raster nach Bedarf einblenden und Layout-Hilfen anzeigen. In meinem neuen Video stelle ich diese Neuerungen vor und zeige anschließend anhand einer Seite, wie daraus ein moderner Einstieg ins Intranet entsteht. Zum Einsatz kommen Bilder, Texte und eine hervorgehobene Karte mit einer Schaltfläche – direkt im SharePoint-Seiteneditor. Was machen flexible Abschnitte möglich? Flexible Abschnitte, auch Flexible Sections genannt, gibt es bereits seit einiger Zeit. Darin lassen sich Seitenbausteine, die sogenannten Webparts, innerhalb eines Rasters frei positionieren und in ihrer Größe anpassen. Auch überlappende Elemente sind möglich: Eine Textfläche kann beispielsweise teilweise über einem Bild liegen. Das bietet besonders für Intra...

Ein übersichtlicher Projektbericht, eine individuell gestaltete Informationsseite oder eine mit Copilot erstellte HTML-Anwendungsseite (HTML app): Solche Inhalte sollen sich künftig ganz selbstverständlich in SharePoint Online nutzen lassen. Mit der angekündigten Funktion „SharePoint: HTML pages“ können reine HTML-Seiten direkt innerhalb der vertrauten SharePoint-Oberfläche angezeigt werden – ohne störende Vorschauleisten oder zusätzliche sichtbare Einbettungsrahmen. In meinem neuen Video zeige ich einen ersten Einblick. Um die Einbettung zu verbessern, kann auch mein WebPart  Smart HTML application page Integrator eingesetzt werden. Dies ermöglicht die nahtlose Einbindung von interaktiven (Copilot-) HTML-Anwendungsseiten (HTML-Apps) ohne störenden Rahmen. Stand September 2026: Die Funktion befindet sich noch in Entwicklung ( Roadmap details ). Laut der im Video gezeigten Microsoft-365-Roadmap ist der Start des Rollo...
