AdvancedDataGrid should be using Virtual item renderers. You can check the DOM and see how many rows are in each column's list.
Is it slow at startup, or when scrolling? Try using a JS profiler to see where the compute time is going. -Alex On 12/8/20, 2:32 AM, "Harbs" <[email protected]> wrote: If you have many rows, you probably want to use an InfinateVScroller to load the rows dynamically as you scroll. Flex only rendered the visible item renderers by default. Royale loads them all by default. I believe some work was done with Virtual Lists, but I’m not sure about AdvancedDataGrid. Using an InfinateScroller to load data as-needed should help a lot. > On Dec 8, 2020, at 12:23 PM, Nallathambi, Varunkumar <[email protected]> wrote: > > Hi, > I feel dead slow in royale application, especially when we have AdvanceDatagrid.
