Question

A canvas app displays a gallery of 400 product records from Dataverse. Each gallery item shows a product image stored as a URL in the record. Users report that the screen takes a long time to render when it first opens, and scrolling is sluggish. Delegation is already correctly configured and the query returns quickly. You need to improve the perceived load time and scrolling smoothness with the least redesign effort. What should you do?

Accepted Answer

Set the gallery's Image control to load images only when items become visible by leaving the default virtualization behavior and reducing the number of controls per gallery template.

Answer

Increase the app's Data row limit for non-delegable queries setting to 2000 so all records and images load at once during OnStart.

Answer

Move the entire product collection into a Collect() call inside OnStart so the gallery reads only from local memory.

Answer

Wrap the gallery's Items property in a ForAll() that pre-fetches every image URL into a variable before display.
