The Kendo Grid multi checkbox filter has the same sort order as the column it belongs to. There is a example of how to correct that and provide a sort here:However that sorts the multiple checkbox filters correctly but it does not persist any existing checked items. If you have pre-existing items checked when this runs it will clear that and just return sorted checkboxes. In our case when we change refresh the datagrid datasource (using setDataSource) it will refresh the filter options while persisting the existing selected checkboxes. However if we want to do that and have the checkboxes sorted then we lose our existing selection.
