Note
For performance reasons, we recommend that you not use the JoinOperand in sort properties, as this significantly increases the number of queries sent to the server.
The following code snippets (auto-collected from DevExpress Examples) contain references to the Sorting property.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
