Vue TreeList - remoteOperations

Notifies the TreeList of the server's data processing operations. Applies only if data has a plain structure.

Selector: DxRemoteOperations

Type:

Object

Mode

Default Value: 'auto'

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.

NOTE

Filtering and sorting are performed on the server side for the ODataStore, but you can change them to the client side by setting the corresponding remoteOperations fields to false. Other operations are always client-side.

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).
