Hello Nicholas,

I think it depends on your custom paging. If you select Top rows for each page in your select method, the  WebGrid sorting only will sort depend on your data. I think your WebGrid does not reload all data, but only partially (pages). That's why it will sort based on data at each page, not all data in all pages.
So, would you mind to let me know your GetData() for custom paging?

Yes,

public HierarchicalList<Sample> GetData(ControlParametersBase parameters,
                                                                Helper helper,
                                                                int startRowIndex,
                                                                int maximumRows,
                                                                string sortExpression)
        {
            int? startRow = startRowIndex;
            var params = parameters;

            var data = GetDataRecords(params,
                                      helper,
                                      string.IsNullOrEmpty(params.CurrentSortOrder) ? sortExpression : params.CurrentSortOrder,
                                      startRow,
                                      maximumRows != 0 ? maximumRows : (int?)null);

            return data;
        }

GetDataRecords call a server-side method with take and skip arguments.

Is it enough?

Many thanks,

Nicolas

Hello Nicolas,

When you used Custom Paging, the sorting would sort each page because the data is loaded for each page (partially). If you want, you would need to handle your own sorting. Our sorting would not work because the data is not loaded all due in Custom Paging mode.
