DataGrid experiments
Explore typed filtering, sorting, selection, virtualization, and CRUD at different dataset sizes.
In this Blazor WebAssembly host: generation, filtering and sorting run on your device, so large datasets depend on its speed.
100
100 records in component memory (browser) · generation 0 ms · edits reset on navigation/reload. This timing measures generation, not browser rendering.

Why it works
This grid holds its dataset in component memory: on the server for Blazor Server, in the browser for WebAssembly. Virtualization reduces rendered rows, not allocation or filtering work. Compare it with the API lab's paged data.
Try it yourself
Compare 100 and 69,420 rows with the same seed. Search, select, edit, copy, and reset. Measure on your own machine.
