<h5 id="GrapeCity_ActiveReports_Design_Designer_DesignerTabChanged_remarks"><strong>Remarks</strong></h5>
<div class="markdown level0 remarks"><p>This event is fired when the user switches between different tabs in the designer interface, such as moving from the &quot;Design&quot; tab to the &quot;Preview&quot; tab.
It allows for the execution of custom logic in response to this change, such as updating UI elements or performing cleanup tasks related to the tab change.</p>
<p>Event handlers can use this event to adapt the application's behavior to the newly active designer tab, enhancing the user experience and 
ensuring the application remains responsive to user actions.</p>
