<h5 id="GrapeCity_ActiveReports_Viewer_Win_Viewer_HandleError_System_Exception__remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>This method is intended to centralize error handling within the viewer control.
It allows for a consistent approach to managing exceptions, such as logging errors or informing the user through the UI.
The actual handling strategy is implemented within the viewer model.</p>
