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.

SharePoint 2010 Script On Demand–give me my scripts right now!

Hi all! May be you are already familiar with sharepoint 2010 script on demand feature. Recently I was playing with it and want to show some examples and explanations how it works.

There is a server control, that is responsible for rendering scripts on demand - ScriptLink .This control has 4 significant properties: LoadAfterUI, Name, OnDemand and Localizable.

  • LoadAfterUI (if true) means that your script link (or script) will be rendered at the vary end of the <form> tag (when all other html elements already loaded). if this property equals to false, script will be inserted right after <form> tag. Internally, methods RegisterStartupScript and RegisterClientScriptBlock used. The only difference between these two methods is where each one emits the script block. RegisterClientScriptBlock() emits the script block at the beginning of the Web Form (right after the <form runat="server"> tag), while RegisterStartupScript() emits the script block at the end of the Web Form (right before the </form> tag).
  • Name - name of script file (or path to that file – read below). This property uses by javascript as key that uniquely identify loaded script.
  • Localizable – if true, sharepoint try to find your script under “_layouts/1033/”
  • OnDemand – the most interesting property, indicates if we need this script load immediately, or if it should be downloaded on demand

Ok, some examples. Imagine we have script file myscript.js directly inside the layouts folder and we want to load it (OnDemand = false) . Its easy:

<SharePoint:ScriptLink runat="server" ID="sl" Localizable="False" LoadAfterUI="False" Name="myscript" OnDemand="False"></SharePoint:ScriptLink>

This action produces this output:

<script src="/_layouts/myscript.js?rev=7KqI9%2FoL9hClomz1RdzTqg%3D%3D" type="text/javascript"></script>

How to extend deployment of sharepoint solution in Visual Studio using "Run PowerShell script" deployment step.

Hi2all! Today I'm going to explain how you can easily extend your deployment tasks using Visual Studio and plugin CKSDEV for Visual Studio 2010. This plugin enhance VS with many custom SharePoint project items (SPI), add additional deployment configuration for your project and some other useful details. One of the most great possibilities that CKSDEV offer are additional deployment steps:

Imagine that after deployment you must create on the site several sharepoint groups and assign permission to them. Using deployment step "Run PowerShell Script" you can place all logic reside to group creation to your custom powershell script file and execute this script file after deployment. We start with creation of script file and then we integrate script in Visual Studio 2010.
I've been created xml file definition for groups that have such structure:


            DOMAIN\FirstName_SecondName

Now lets create two files - in the first we are storing all functions and the second will use functions from this file. Call the first file "functions.ps1" and the second - "starter.ps1". "functions.ps1" include function "AddGroups" that actually read xml with group definition and adds required groups to a site. I will explain in other post how my code work, but it rather simple, if you have base knowledges of powershell you easily understand it:
