Sorting tables with dynamically loaded branches

Webix JS
1

Hi, I’m testing out Webix for our product. We’d like to use a tree table with dynamically loaded branches. I’ve built a table like this:

  webix.ui({
    container:"tree",
    view:"treetable",
    position:"flex",
    columns: [
      { id: "name", template:"{common.treetable()} #name#", width: 300, header: ["Name", { content: "textFilter" }], sort: "string"},
      { id: "description", fillspace: true, header: "Description", sort: "string"},
      { id: "created_at", width: 150, header: "Created At", sort: "datetime"},
    ],
    url: "/feeds/node",
    datatype: "json"
  });

Dynamic branch loading works fine, as does sorting. However, if I first sort a column, and then expand a new branch, the nodes on the new branch are not sorted corrected. They seem to be sorted however they come back from the server. Is this a known issue, and is there a way to work around it?

Thanks!

This is expected behavior.

Sorting is one time operation, not a persistent state. So if you are adding new items in the treetable after sorting they will be added as is, without automatic re-sorting.

It possible to catch the loading event and reapply sorting to the treetable after that.

Thanks for the response! Would you mind pointing me at some documentation or examples of hooking into a loading event, and also how to manually apply sorting to a treetable?
