JavaScript/jQuery TreeList - remoteOperations
Notifies the TreeList of the server's data processing operations. Applies only if data has a plain structure.
Server-side data processing improves the UI component's performance on large datasets. When the server does not implement particular operations (and/or the corresponding remoteOperations fields are false) they are executed on the client. Note that the UI component may send queries to the server while executing a client-side operation.
The following table lists the possible remoteOperations configurations and the operations the server should implement. The server should also implement additional operations depending on the used UI component functionality.
| Setting | Required server-side operations | Additional server-side operations |
|---|---|---|
remoteOperations: { filtering: true } |
filtering | - |
remoteOperations: { sorting: true } |
sorting | filtering* |
remoteOperations: { grouping: true } |
grouping, filtering | sorting* |
- If this functionality is used in the UI component.
When operations are performed on the server side, the TreeList does not support:
- sorting, grouping, and filtering by columns with the calculateCellValue or calculateDisplayValue property defined;
- custom sorting using functions (that is, calculateSortValue accepts strings only).

grouping
Grouping is required only when a user can filter data using a header filter.
