INTRODUCTION
Microsoft Dynamics 365, a powerful platform for managing customer relationships and business processes, continues to grow in capability and flexibility. But while its out-of-the-box features meet many business needs, they can sometimes fall short when highly customized or visually dynamic user interfaces are required.
That’s where the PowerApps Component Framework (PCF) comes into play. PCF empowers developers to create reusable, visually engaging, and fully responsive components that seamlessly integrate into model-driven apps and canvas apps. With PCF, you’re no longer limited by traditional form controls or UI constraints—you’re free to build controls that are both powerful and tailored precisely to your business needs.
In this blog, we’ll explore what PCF is, why it’s a game-changer for Dynamics 365 developers, and how you can harness its potential to transform user experiences and boost productivity.
PROS AND CONS OF PCF
PROS
- Modern and Flexible UI: PCF allows developers to use modern web technologies like TypeScript, HTML, CSS, and external JavaScript libraries to create highly customizable and responsive components that blend seamlessly with Dynamics 365 and Power Apps.
- Seamless Integration with Dataverse: PCF controls are natively supported within the Microsoft Dataverse environment, allowing tight coupling with form fields, datasets, and business rules — making data interaction smooth and intuitive.
- Reusability across Apps: Once developed, a PCF control can be reused across different model-driven or canvas apps, ensuring consistency in UI and reducing development effort over time.
- Enhanced User Experience: Standard controls often fall short in terms of interactivity or visual appeal. PCF enables richer user experiences — such as drag-and-drop interfaces, visual indicators, and custom input methods.
- Controlled DOM Manipulation: Unlike traditional web resources, PCF provides better encapsulation and lifecycle management, giving developers more control over how and when components render or update.
CONS
- Steeper Learning Curve: PCF development requires knowledge of TypeScript, web bundlers like Webpack, and the Microsoft Power Platform CLI. This can be challenging for traditional Dynamics developers unfamiliar with front-end technologies.
- Limited Debugging Tool: While PCF supports local testing, debugging PCF controls within the Dynamics environment can sometimes be complex due to the encapsulated rendering engine and asynchronous behavior.
- Deployment Overhead: Deploying PCF components involves multiple steps including packaging, solution imports, and sometimes manual dependency management — making the deployment process slightly more involved compared to standard customizations.
- Performance Consideration: Poorly optimized PCF controls can negatively impact form performance. Developers must pay special attention to data handling, rendering speed, and memory usage to maintain a responsive experience.
- Limited Canvas App Support: While PCF is supported in canvas apps, certain features — especially dataset-bound controls — may behave differently or be limited compared to model-driven apps.
PREREQUISITES
KNOWLEDGE REQUIREMENTS
- Basic Understanding of Dynamics 365 and Power Apps: Familiarity with how model-driven apps work, the structure of forms, fields, and Dataverse (formerly CDS) is essential. You should understand where PCF controls fit in the application layer.
- Web Development Skills: PCF is rooted in modern web technologies. You should have working knowledge of TypeScript, HTML, CSS and JavaScript libraries.

- Power Apps Developer Environment: Sign up for a free Power Apps developer plan to get your own Dataverse environment where you can test your PCF components.
USE CASE
We have developed a custom PowerApps Component Framework (PCF) control for the Email entity in Dynamics 365. This control enhances email usability by displaying related Case documents in a custom grid and streamlining the process of attaching SharePoint documents to emails. It also includes smart handling for large files via automated linking.
Key Features
- Integrated PCF Control: Embedded directly into the Email form in Dynamics 365.
- Document Display: Automatically fetches and displays all related Case or other entity documents in a tabular grid.
- User Interaction: Each document row includes:
- A checkbox for multi-selection.
- A “Download” button to download the document.
- A “Preview” button for inline preview (if supported).
User-Friendly Interface
- Tabular Layout: Displays document name, size, and actions in a structured grid.Multi-Selection: Allows users to select and attach multiple documents.
- Quick Access: “Dowload” link enables direct file download.
- Preview Support: Inline preview for supported file types.
Direct Attachments:
Files ≤ 5MB are directly attached to the email.
Large File Linking:
Files > 5MB are linked via URLs in the email body.
Visual Indicators:
Attachment status clearly shown (e.g., attached vs. linked).
Error Messages:
User-friendly error handling and guidance included.
Automatic Refresh
After clicking “Attach Selected Documents”, the email form automatically refreshes to reflect the new attachments.
File Preview Functionality
- Clicking “Preview” opens a modal window.
- Supported file types are rendered for inline preview.
- A Close button is included.
- A loading indicator is displayed during file preparation.
If preview fails due to SharePoint/browser restrictions, the “Open File” link opens it in a new tab or the file can be downloaded via the “View” link.
HOW TO USE THIS PCF
- Import the EmailAttachSPDocControl solution into your Dynamics 365 environment and publish all customizations.
- Navigate to the Email entity and create a new lookup field to either Case, Lead, or Contact (for referencing related documents) if the fields is not available
- Add the new lookup field to the Email form if not available.
- Open field properties, go to the Controls tab.
Add Control and choose “EmailAttachSPDocControl.”
Set the following parameter values RegardingObjectd_DisplayName
Set Email ID to activityid
Configure HTTP flow POST URL by pasting the copied flow URL
Paste the relevant SharePoint site URL
- Save and publish the email form, then refresh the form to see the control appearing on the form.
You can get the HTTP POST url by going to the imported solution -> open HTTP flow -> enable it (if disabled) -> copy the HTTP POST URL
Navigate to the sharepoint site -> copy the site URL
