SharePoint: Build Forms with Power Apps

Key insights

• Demo summary: Ivan Wilson shows how to customize SharePoint document library forms using Power Apps to improve layout, add validation, and streamline processing with hidden fields and flows.
  He demonstrates practical steps and real-world tips from a Microsoft 365 & Power Platform weekly call.
• How to start: Open a SharePoint list and choose Integrate > Power Apps > Customize forms to auto-generate a canvas app connected to the list.
  This gives a ready-made form you can edit and publish to replace the default SharePoint form instantly.
• Form modes and control: Use the SharePointIntegration control with formulas like OnNew, OnEdit, OnView, and OnSave to manage behavior across New, Edit, and View modes.
  Set variables in these handlers so the app submits the correct form and branches logic cleanly.
• Validation and automation: Add inline validation and use hidden fields to collect metadata without cluttering the UI.
  Trigger Power Automate flows from the form to handle approvals, document moves, or other automated processing.
• Layout and responsiveness: Design responsive forms with containers and Screen.Size checks so forms work well on phones, tablets, and browsers.
  Duplicate and customize screens for New/Edit/View to present only relevant fields and reduce user errors.
• 2025 updates and best practices: Use the new Plan Designer (May 2025) to import data models from SharePoint or Excel and create tables that back your forms.
  For large lists, group or hide fields, use Patch for complex updates, and favor accessibility and consistent branding for better adoption.

Overview of the Video

The YouTube demo, published by Microsoft, showcases how Ivan Wilson customizes a SharePoint document library form using Power Apps. It focuses on improving form layouts, adding validation, and streamlining processing with hidden fields and automated flows. Moreover, the session came from a Microsoft 365 & Power Platform weekly call held on October 9, and it targets makers who want practical, low‑code solutions. Consequently, the video balances conceptual explanation with hands‑on steps to help viewers replicate the approach.

Demo Walkthrough and Key Steps

First, the presenter opens the document library form and uses the Integrate menu to launch Power Apps, which auto‑generates a canvas app connected to the library. Then, he duplicates screens to create mode‑specific layouts, naming them for New, Edit, and View modes, and wires the app to the SharePointIntegration control to manage mode transitions. In addition, the walkthrough shows how to set variables in the form mode events so that the same OnSave handler can submit different forms depending on the current mode. As a result, the demo delivers a clear pattern for organizing forms that simplifies maintenance and reduces errors.

Techniques Demonstrated

The video highlights several practical techniques, including responsive layout design, field validation, and use of the Patch function for complex column types. For example, the presenter demonstrates grouping fields, hiding unnecessary inputs in New mode, and using hidden fields to capture metadata without cluttering the interface. Furthermore, he integrates flows via Power Automate to automate downstream processing and illustrates when to trigger a flow versus when to use a direct Patch call. Consequently, these methods improve data quality and streamline how records move through business processes.

Tradeoffs and Challenges

While the approach offers clear benefits, it also introduces tradeoffs around complexity and maintainability that teams must consider. On one hand, custom forms deliver tailored experiences and better validation, but on the other hand they add layers that non‑developers might struggle to support in the long term. Moreover, heavy customization can complicate upgrades or migration to newer tools, and using many conditional controls can affect performance on older devices. Therefore, teams need to balance user experience gains against ongoing management costs and performance impacts.

Scaling, Governance, and Best Practices

To scale these solutions, the demo emphasizes reusable patterns such as screen duplication for form modes, consistent naming, and storing logic in predictable places. Additionally, teams should document their customizations and use environment governance to control who publishes changes, because uncontrolled edits can break integrated flows or connected lists. As a best practice, makers should also test forms with realistic data volumes and mobile devices to identify delegation or rendering issues early. Finally, planning around a governance model helps preserve long‑term stability while still allowing business users to iterate quickly.

Practical Recommendations and Takeaways

In summary, the video provides a pragmatic path for customizing SharePoint forms with Power Apps that suits many common organizational needs. It shows how to create role‑specific views, add validation rules, and automate follow‑up actions without deep developer involvement, but it also cautions teams about maintenance and performance tradeoffs. Looking ahead, makers should adopt modular designs, document decisions, and apply governance to keep solutions sustainable while taking advantage of new features such as the updated Plan Designer. Overall, the demo offers a balanced, actionable guide for teams who want to modernize their SharePoint forms and processes.
