Stop IGraphicsContainer delete Refresh Automatically

Question

Below is my code where I am first collecting graphic elements to delete, and then iterating the list to delete the elements. Issue is that the ArcGIS gets refreshed after every delete graphContainer.DeleteElement(item). How can I prevent it for automated refresh.

  IActiveView activeView = pMxDoc.ActiveView;
  IPageLayout pageLayout = activeView as IPageLayout;
  IGraphicsContainer graphContainer = pageLayout as IGraphicsContainer;
  graphContainer.Reset();
  IElement pElement;
  List<IElement> toDel = new List<IElement>();
  pElement = graphContainer.Next();   
  while (pElement != null)
  {
    //if (pElement is ITextElement)
    if (pElement is IMapFrame)
    {          
    }
    else
    {
      toDel.Add(pElement);        
    }
    pElement = graphContainer.Next();
  }
  foreach (IElement item in toDel)
  {
    graphContainer.DeleteElement(item);
  }

You should wire the IActiveViewEvents.ItemDeleted Event.

https://desktop.arcgis.com/en/arcobjects/latest/net/webframe.htm#IActiveViewEvents_ItemDeleted.htm

From there you can control what happens, whether a refresh, partial refresh, or nothing.

I tired following and has worked for me.

I set the DelayUpdateContents property on IMxDocument and it has done the trick !

mpMxDoc.DelayUpdateContents = true;

Thanks for all the replies.
