Improve Dynamics 365 Performance by Fixing PCF Refresh Storm
Developers working with Power Apps Component Framework (PCF) dataset controls on Dynamics 365 Model-Driven Apps can encounter a common issue: triggering a refresh in one PCF control causes all controls on the form to fire their updateView() methods, leading to unnecessary re-rendering, performance issues, and debugging challenges. This issue arises because PCFs using virtual rendering share a single React rendering tree that treats any dataset refresh as a form-wide data change. To resolve this, the article suggests two key fixes: implementing a context.updatedProperties guard in the updateView() method to ensure only relevant data changes trigger a re-render, and using React.memo to prevent re-renders when component props haven't meaningfully changed. These strategies effectively isolate control renders, improving performance and user experience by preventing unwanted refresh storms.
