public void BeginSelection()
Public Sub BeginSelection
A View allows a sequence of row selection operations to be performed without having the View render itself after each modification. To do this, the code performing sequential changes must be enclosed within calls to the BeginSelection and DataControlBase.EndSelection methods. This improves performance, and avoids unnecessary rendering operations.
The following code snippets (auto-collected from DevExpress Examples) contain references to the BeginSelection() method.

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.
