Greetings from Syncfusion.
To bind a remote data to the server using Angular Observables, we are using Async Pipe. This has been discussed in the following Help Document.
Grid actions like Paging, Sorting were also handled and their query will be executed within the dataStateChange event.
Enable pager in the Grid for better performance. Use the pager with the Observables concept which will bring the data to the Grid on pagination. Refer to the following Help Document.
If you wish to use the unpaged scrolling, you can prefer the Virtualization concept of the Grid with the Observables.
Refer to the following demos.
