  <h5 id="GrapeCity_ActiveReports_Design_Selection_remarks"><strong>Remarks</strong></h5>
  <div class="markdown level0 remarks"><p>This class provides functionality to manage the selection of components in the designer. It allows querying the current selection, changing the selection,
and listening for selection changes. The selection can include controls, sections, or other design-time components. This class is particularly useful for
extending the designer's functionality or integrating with other parts of the application that need to react to changes in the designer's selection state.</p>
