Data Grid - Performance

The igGrid control provides several options and features that increase its performance.
The Virtualization feature improves rendering time if the grid has a large set of records.
The remote Paging feature allows the grid to request its data from the server in small chunks per page.
The remote Filtering feature executes the search operation on the server and returns the result to the client.
This sample is designed for a larger screen size.
On mobile, try rotating your screen, view full size, or email to another device.
