Using Grouping Expressions
Updated over 6 months ago
Overview
The GroupDescriptorCollection contains Expression property which is used to create flexible grouping conditions. Expression is a string that contains the column name followed by "ASC" (ascending) or "DESC" (descending). Columns are sorted ascending by default. Multiple columns can be separated by commas. Multiple grouping descriptors can be separated by semi column symbol.
