How to disable drag-and-drop events in calendar.

Hi all! Based on this sharepoint.stackexchange question.

May be in some reasons you want to disable all drag-and-drop event for your calendar list. I don’t know if it possible through C# code, but it’s possible through javascript. In *SP.UI.ApplicationPages.Calendar.js* there is a factory method

SP.UI.ApplicationPages.CalendarContainerFactory.create.This method creates and initializes instance of calendar using javascript. Among other parameters this function accepts context object that contains initialization info about calendar (cctx object). This object contains property DataSources (Array) and each array element is an object that has property named disableDrag. disableDrag false by default. The main idea is to substitute factory method and pass updated cctx object, that has disableDrag=true for every datasource. Edit page with calendar and add content editor web part. In content past this code:

<script type='text/javascript'>
  ExecuteOrDelayUntilScriptLoaded(function(){
    var calendarCreate = SP.UI.ApplicationPages.CalendarContainerFactory.create;
        SP.UI.ApplicationPages.CalendarContainerFactory.create = function(elem, cctx, viewType, date, startupData) {
            if(cctx.dataSources && cctx.dataSources instanceof Array && cctx.dataSources.length > 0){
                for(var i = 0; i < cctx.dataSources.length; i++){
                    cctx.dataSources[i].disableDrag = true;
                }
            }
            calendarCreate(elem, cctx, viewType, date, startupData);
        }
  }, 'SP.UI.ApplicationPages.Calendar.js');
</script>

or through code (don’t forget about proper disposing):

var site = new SPSite("http://localhost/sites/test/");
var web = site.OpenWeb();
var wpManager = web.GetLimitedWebPartManager("Lists/cal/calendar.aspx", PersonalizationScope.Shared);
var contentEditor = new ContentEditorWebPart();
var xmlDoc = new XmlDocument();
var xmlElement = xmlDoc.CreateElement("HtmlContent");
xmlElement.InnerText = @"<script type='text/javascript'>
      ExecuteOrDelayUntilScriptLoaded(function(){
		var calendarCreate = SP.UI.ApplicationPages.CalendarContainerFactory.create;
        SP.UI.ApplicationPages.CalendarContainerFactory.create = function(elem, cctx, viewType, date, startupData) {
            if(cctx.dataSources && cctx.dataSources instanceof Array && cctx.dataSources.length > 0){
                for(var i = 0; i < cctx.dataSources.length; i++){
                    cctx.dataSources[i].disableDrag = true;
                }
            }
            calendarCreate(elem, cctx, viewType, date, startupData);
        }
  }, 'SP.UI.ApplicationPages.Calendar.js');
    </script>";
contentEditor.Content = xmlElement;
wpManager.AddWebPart(contentEditor, "Main", 0);

And that’s it. This code disables drag and drop for events for month, week, and day view. Hope this helps.
