When using the grid in navigatable mode, cells are correctly described, as seen in line 6014 of kendo.grid.js:
if (navigatable) {
rowTemplate += ' aria-describedby=\'' + column.headerAttributes.id + '\'';
}
This simple, yet essential functionality is missing in TreeList.
When attempting to use the filter function on a TreeListDataSource, the linked TreeList control reports that are no records to display regardless of what filter is entered. This includes attempts to clear/reset the filters using an empty object/null and behaves the same regardless of whether serverFiltering is enabled.
The TreeListDataSource object contains the expected records.
