Sorting Lists in the Report Viewer
The Report Viewer provides an interactive sorting capability for list-style reports.
To reorder the records in a list, click on header for that column. Multi-column sorting can also be done by holding down the Shift key while clicking a 2nd or 3rd column.
Columns being sorted will show an up or down arrow on the right side of the header area indicating ascending or descending sorting. Additional clicks of the same column will toggle between the sort orders.
When you export the report to another file type, the sort order in effect at the time will be used for the export.
