Tree Grid sort children nodes, not just the roots

  Yes, you can sort the children nodes in the TreeGrid, we actually do it in this demo: https://demo.aspnetawesome.com/TreeGrid#Tree-Grid-with-CRUD-operations in the `GridModelBuilder` `GetChildren` or `GetChildrenAsync` you need to sort the data according to the `GridParams`, and usually you would do this by calling `gmb.OrderBy(children.AsQueryable());` example: gmb.GetChildren = (node, nodeLevel) => { var children = result.Where(o => o.Parent == node); return gmb.OrderBy(children.AsQueryable()); };

  • I see your sample, but not seem sorted by a column (ex. ID)

  • Is it possible sort by only one column (ex. id) ?

  • yes, if you want to remove the sorting from other columns when you click on another use `.SingleColumnSort(true)` on the `Grid`, you can see it here: https://demo.aspnetawesome.com/GridDemo/Sorting (there's a checkbox setting for the demo grid)
