Ever get frustrated when looking at a SharePoint calendar and for a particular month you've clicked expand all then move to a different   month and find that you're back in collapsed view.

Well you can change this by making some modifications to the CORE.JS file but keep in mind that you migh t have to redo this customization following any SharePoint service packs that you might apply.

There's basically 2 functions  that  you need to change

• GetMonthView -  called whenever you click the Expand All or Collapse all buttons.
• MoveToViewDate  - called when you navigate to a new month

Here's the new code that you'd need in those functions

function GetMonthView(str)
{
 //Added by Andy Bonner to memorize state
 SetCookie('ExpandCollapse',str,'');
 //Added by Andy Bonner to memorize state


 var wUrl=window.location.href;
 var ExpWeek=document.getElementById("ExpandedWeeksId");
 if(ExpWeek!=null)
  ExpWeek.value=str;
 else
  return ;
 SubmitFormPost(wUrl, true);
}


function MoveToViewDate(strdate, view_type)
{
 //Added by Andy Bonner to keep expanded or collapsed state
 var ExpCol = GetCookie('ExpandCollapse');
 if(ExpCol != null)
 {
  var ExpWeek=document.getElementById("ExpandedWeeksId");
  if(ExpWeek!=null)
   ExpWeek.value=ExpCol;
 }
 //Added by Andy Bonner to keep expanded or collapsed state



 var wUrl=window.location.href;
 if (strdate !=null)
  wUrl=StURLSetVar2(wUrl,"CalendarDate",escapeProperly(strdate));
 if (view_type !=null)
  wUrl=StURLSetVar2(wUrl,"CalendarPeriod",view_type);
 SubmitFormPost(wUrl, true);
}
