Server filter and sort at the same time

[Matjaz]

I enabled server filtering and sorting. How can I filter and sort with one method. I don't want two request to the server.
Is it save to use filter and sort method one after another or there will be multiple request send to server?

Hi Matjaz,

You can apply multiple operation descriptors, such as filter, sort, group, paging, etc. via the query method of the DataSource. Note that this method will override the existing descriptors, therefore you will need to pass the descriptors for the operations you want to persist. Similar to the following:

dataSource.query({
  sort: { field: "ProductName", dir: "desc" },
  filter: { field: "ProductName", operator: "startswith", value: "Manjimup" },
  page: dataSource.page(),
  pageSize: dataSource.pageSize(),
  group: dataSource.group()
});

Regards,
Rosen
