Customizing Context Menu in SharePoint 2007


A couple of days back I got an email request from one of my friends who wanted to know that how can he customize the context menu for items in the document library for WSS 3.0, and the very next day I was assigned a project at my job in which I had to do exactly this as one of the requirements. So today I am writing this post to put a little light on how we can customize the context menu for items in a document library. Ok I am going to illustrate this with the help of an example problem.

Problem Statement:
Whenever we upload an excel file in the document library, the context menu should have an extra item in named as lets say "View Excel Sheet as a webpage" ofcourse in this post I am not going to illustrate how we would render that excel sheet as webpage to the user but this is just to give you an idea of how things are done. This menu item would also have an "excel" like icon along site it and whenever we will click on the menu item it would just alert the user the location of the excel file .i.e. where it is stored with reference to the site.

Ok now having stated the problem lets get to some basics first.

The context menu is itself a javascript program means that the context menu is generated by a javascript code . This javascript program can be found at

\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\1033\Core.js

Yes the name of the file has changed to Core.js from ows.js, menus in Windows SharePoint Services and SharePoint Portal Server 2003 were located in a javascript files at the following location

\Program Files\Common Files\Microsoft Shared\web server extensions\60\TEMPLATE\LAYOUTS\1033\ows.js

Ok now lets dig in a bit in the Core.js file, in the Core.js file the main function responsible for the document library drop down menus is AddDocLibMenuItems(m, ctx) and this provides a hook by which we can insert additional menu items.

The first few lines of the function are as follows

if (typeof(Custom_AddDocLibMenuItems) !="undefined")
    {
        if (Custom_AddDocLibMenuItems(m, ctx))
            return;
    }

Ok now what this piece of code does? it is basically looking as to whether a function named Custom_AddDocLibMenuItems is defined or not, if it is defined then it simply calls it. So the main idea here is to override this Custom_AddDocLibMenuItems function by our own script which we can use to extend the context menu, adding new items.

Note: It is recommended that you make a copy of your Core.js before you make any changes to it.

Ok now we can override the Custom_AddDocLibMenuItems function in core.js adding our own script as follows.

function Custom_AddDocLibMenuItems(m, ctx)
{
    var strDisplayTextCustom = ‘View Excel Sheet in Browser’;

    setDocType();

    if(currentItemAppName.toLowerCase() == "microsoft office excel")
    {
          strAction="alert(ctx.HttpRoot+unescapeProperly(currentItemFileUrl))";
  
           var strImagePath = ctx.imagesPath+"XLS16.GIF";
         
           // Add menu item
           CAMOpt(m, strDisplayTextCustom, strAction, strImagePath);
 
          // add a separator to the menu

           CAMSep(m);
   }
    return false;
}

How does the function above works?

The Custom_AddDocLibMenuItems function takes two parameters m and ctx, the first parameter m is basically representing the menu object itself, where as ctx provides HTTP context information about the web request. To add an item to the menu only one function call is needed.

CAMOpt(m, strDisplayTextCustom, strAction, strImagePath);

The CAMOpt function takes 4 parameters which are as follows:

1) The menu object to add item to.
2) The display text of the menu item.
3) Javascript action to perform when item is clicked.
4) Path to an image associated with the menu item.

CAMSep function simply adds a separator bar to the menu. Finally the function returns a false which means that standard menu items should also be included, if we had returned true then standard menu items would not have been included.

Having done all this simply save the Core.js file and open your sharepoint site and a few excel sheets to the document library and check its context menu. The context menu should be as shown in the image below.

Interesting query from a friend across the border :)

Today a friend from across the border scrapped me on orkut and asked an interesting question

 

is it necessary to install sharepoint to create the web parts? I have windows 2000?

 

"I have to use existing sharepoint webparts in my aspx page. for that do i need to install sharepoint ? "

 

 

Well this is quite a common question so I wanted to post the answer to it on my blog

 

So there are a few things we should keep in mind.

 

a)      To develop SharePoint webparts, we need a machine that runs Windows 2003, in case of any other operating system you can always Remote Desktop to work on another machine which has Windows 2003 this is quite a common practice.

 

b)      Webparts cannot run in complete isolation so you need to create a sample SharePoint site to play with the webparts you create.

 

c)   I assume SharePoint Service development is integrated with the Visual Studio .Net IDE on your machine (we’re talking about the .Net 1.1 framework. In .Net 2.0, Web Part development support is default) so that you have Web Part templates as you create a new project.

      d)  To make your life easy download Visual Studio 2005 Extensions 3. 0 for WSS, that really makes the webpart creating  process  quite easy. Click here to download Visual Studio 2005 Extensions for WSS.
