Color coding calendar in SharePoint 2010

We put in place for our projects, SharePoint workspaces where we can share documents and collaborate with our client on the progress of their projects.
Among other items, I have created a team calendar mainly to share meetings, travels and vacations plans. Because I also wanted to manage differently those event types, I have created a Category for each of them.
·         Meeting
·         Holiday
·         Travel
·         Other
Here is my calendar with some information.

Because I think that color coding would help to easily identify event categories, I have created the following custom view (note that I have chosen not to display start and end time).

Here is the procedure to customize your calendar to be color coded.
Step 1: Create a new column [Color]. This will be used to define the color of the cell based on the category.
On the list settings page, click on Create Colum link. Name the new column “Color”, and set the type of information as Calculated (calculation based on other columns).
The formula is the following:
Finally, set The data type returned from this formula is: to Single line of text.
=IF([Category]="","LightCyan",
IF([Category]="Meeting","DodgerBlue",
IF([Category]="Holiday","Tomato",
IF([Category]="Travel","LawnGreen",
IF([Category]="Other","DarkBlue","")))))
The result of this column will be a color name based on a category. Note that category should reflect ones you choose and color names can be changed.

Step 2: Create a new column [EventText]. This will contains the html code that will display the event text on the calendar view (including the color scheme).
As above, create a new calculated column with the following formula:

="<span style='position:relative;display:inline-block;width:100%;'>
<span style='width:100%;display:inline-block;text-align:center;border:1px solid "&[Color]&";position:absolute;color:"&[Color]&";'>"&[Title]&"</span>
<span style='display:inline-block;width: 100%;background-color:"&[Color]&";text-align:center;border:1px solid;z-index:-1;filter:alpha(opacity=20);opacity:0.2;'>"&[Title]&"</span></span>"
Note that we used the previously calculated column [Color] to define the cell color, and we also use column [Title] to display the event title inside the cell (you can also display Start Time and End Time if requested).
This is up to you to define your own style, this is simply html syntax.

Step 3: Define [EventText] column as the display on the calendar view.
You now need to create a new view for this calendar. This new view should be a Standard Calendar format view. Define properties as you wish. The important part is to display our newly created column [EventText] to replace the default Title.

Let’s now save the view and check the result.

Not so good isn’t itL. It displays the html code instead of interpreting it. To solve this, we need to insert JavaScript code into the page.
Here is the JavaScript code (such kind of code can be found in MSDN web site or in some blogs like techtrainingnotes.blogspot.com).


// Color coded calendars for SharePoint 2010
<script>

// TechTrainingNotes.blogspot.com
// load our function to the delayed load list
_spBodyOnLoadFunctionNames.push('colorCalendarEventLinkIntercept');
// hook into the existing SharePoint calendar load function
function colorCalendarEventLinkIntercept()
{
  if (SP.UI.ApplicationPages.CalendarNotify.$4a)
  {
    var OldCalendarNotify =
SP.UI.ApplicationPages.CalendarNotify.$4a;
    SP.UI.ApplicationPages.CalendarNotify.$4a = function ()
      {
        OldCalendarNotify();
        colorCalendarEventLinks();
      }
  }
  if (SP.UI.ApplicationPages.CalendarNotify.$4b)
  {
    var OldCalendarNotify =
SP.UI.ApplicationPages.CalendarNotify.$4b;
    SP.UI.ApplicationPages.CalendarNotify.$4b = function ()
      {
        OldCalendarNotify();
        colorCalendarEventLinks();
      }
  }
  // future service pack change may go here!
  // if (SP.UI.ApplicationPages.CalendarNotify.???)
}
// hide the hyperlinks
function colorCalendarEventLinks()
{
// find all DIVs
  var divs = document.getElementsByTagName("DIV");
  for (var i=0;i<divs.length;i++)
  {
    // find calendar item DIVs
    if (divs[i].className.toLowerCase()=="ms-acal-item")
    {
divs[i].innerHTML = divs[i].innerHTML.replace(/&lt;/g,'<').replace(/&gt;/g,'>');
    }
    // find "x more items" links and re-remove links on Expand/Contract
    if (divs[i].className.toLowerCase()=="ms-acal-ctrlitem")
    {
      var links = divs[i].getElementsByTagName("A");
      if (links.length==1)
      {
        links[0].href="javascript:colorCalendarEventLinks();void(0);"
      }
    }
  }
}
</script>
To include the code into the page, there are 2 solutions:On SharePoint Designer, open your SharePoint site. On the left menu, select Lists and Libraries, then click on your Calendar name on the main screen. Right Click on the view you want to color code (or create a new one first) and select Edit File in Advanced Mode.
·         Using SharePoint Designer, the JavaScript code will be added to the page code directly
·         Using Content Editor Web Part, the JavaScript code is embed in a WebPart.
Using SharePoint Designer

Identify the section below to copy your JavaScript code inside

Save and check the result.
Click on the image to zoom
You can choose to leave items like this or modify CSS styles to remove the green box around your events.
Search the section <style type="text/css"> and replace with this: 
<style type="text/css">
.ms-acal-time {
  display:none;
}
.ms-acal-selected, .ms-acal-item {
  background:none;border:0px;
}
.ms-acal-sdiv span {
  margin-left:-47px;
}
.ms-acal-sdiv div.ms-acal-title span {
  margin-left:0px;
}
</style>
Save and check the result. Now we have the expected result J.
Using Content Editor Web Part
First of all, the script above should be saved into a txt document and uploaded in one of your site library.
Click on the image to zoom
On your custom Calendar View, select Edit page on the Site Actions menu.
Add a Content Editor Web part to Main section; this web part is located under Media and Content category. Edit the web part. Set ContentLink to your script document’s URL and Chrome type to None (this will remove web part title and borders)
Click on the image to zoom

Save and check the result.
The drawback of this solution is that you will not be able to select other views for this calendar,
where with the SharePoint Designer method, all views are still accessible.

Because of this I prefer to use the SharePoint Designer method.

Sorry Anonymous man, i miss your previous comment. I am sorry i do not have the environment anymore and cannot make tests. I think this should be achieved the same way using JavaScript and checking why not page name (or URL)

Hi, the code works great. However, "Exaned all" and "Collaps all" does not work. The color and the title is gone when I click those buttons and it shows the EventText script. Can you help me out?

Alexander said...

This is almost exactly what I was looking for. I wanted to modify it to display &Created By& rather than the title but unfortunately said column is inaccessible via a calculated column. Is there a way around this?

Jeremy Cottino said...

Hello guys, as i said i don't have the platform anymore so it's difficult to help you :)

Hi Jeremy,

I got an issue, when we put mouse over calendar event, it showing "EventText" related code written in calculated column like span tags. I need to solve this issue.

Thanks in advance.

Jeremy Cottino said...

This seems to be related to JavaScript inserted. I recommend you to check the source code generated of the page and check, you may need to update the code to change this.

I know this does not falls into this category but do you have any idea on how to remove weekends from a calendar in SP 2010? I've tried several scripts and they don't deliver the final solution.
thanks!

Hi Mike,
You can check this article, it's for SP2007 but might help you to find a better solution: http://blog.pathtosharepoint.com/2008/12/17/calendar-weekdays-only/.
