SharePoint Customization Tricks: Part I

This multipart series of articles is intended to help you getting ramped up with SharePoint Customization. It's about modifying the default SharePoint user experience, list forms customization, branding, skinning SharePoint portals, etc. When I looked around the "SharePoint Landscape", I noticed the lack of documented experiences in the SharePoint customization area and thus this multipart series of articles was born.

Prerequisites

First you need to have prerequisite skills in .NET Development and in particular ASP.NET Development, you should also have basic understanding of JavaScript, SharePoint and how to use it from the User Interface and of course you should have some experience in using the SharePoint customization tool (SharePoint Designer).

Trick #1 : Hiding List View Toolbar Menu Items!

 

I've gone through SharePoint projects on different scales; a common requirement among most of these projects is hiding some menu items that are implemented by default within the framework of SharePoint. The obvious choice from the SDK is HideCustomAction ! After digging through the web, I found out the following:

• The "HideCustomAction" feature can merely hide the items which have been rendered through the "CustomAction" feature framework such as Site Actions and Site setting.... etc.
• ECB (Context Menu) items are rendered by JavaScript from Core.js file so we can't hide them via "HideCustomAction" feature. However, you can add a new menu item in the ECB menu through "CustomAction" feature and hide it again through The "HideCustomAction" feature. In other words," HideCustomAction" feature can be used to hide the ECB menu items that you created via CustomAction but can't be used to hide the out of the box menu items.
• The ListViewWebPart menu items ( New menu, Upload menu, Actions menu,... etc ) are rendered through a class library as a web control from the Microsoft.SharePoint.dll so they can't be hidden through The "HideCustomAction" feature.

Hmm, I thought of delving back into the world of JavaScript and I came up with some generic functions that can be used to hide any menu item in SharePoint and I decided to share them with the community.

hideListViewToolbarItems("Edit in Datasheet","export to Spreadsheet","view rss feed","settings:create view"); 

function hideListViewToolbarItems()
{       

var menuItem;        
var menuItemName;
var menuItemIndex=-1;
var menuItemNames=new Array("edit in datasheet","open with windows explorer",
"connect to outlook",'export to spreadsheet','view rss feed','alert me'
,"create column","settings:create view","list settings",
"document library settings","explorer view","all documents",
"all items","modify this view","view:create view","new document",
"new item","new folder","upload document","upload multiple documents");
var menuItems = new Array("EditInGridButton","OpenInExplorer","OfflineButton",
"ExportToSpreadsheet","ViewRSS","SubscribeButton","AddColumn",
"AddView","ListSettings","ListSettings","View1","DefaultView",
"DefaultView","ModifyView","CreateView","New0","New0",
"NewFolder","Upload","MultipleUpload");             
var allMenuItems = document.getElementsByTagName('ie:menuitem');

for(var i = 0; i < hideListViewToolbarItems.arguments.length; i++ )
{                                                                          
          menuItemName= hideListViewToolbarItems.arguments[i].toLowerCase();
          for (j=0;jif(menuItemNames[j]==menuItemName)
                   {                                    
                             menuItemIndex = j;
                             break;
                   }
          }          

          menuItem=menuItems[menuItemIndex];
          for (var l = 0; l < allMenuItems.length; l++)
          {                 
                   if(menuItemName.indexOf(":")!=-1)
                   {
                             menuItemName = menuItemName.split(":")[1];
                   }
                   if (allMenuItems[l].id.indexOf(menuItem)!=-1
                    && allMenuItems[l].text.toLowerCase() == menuItemName )
                   {                 
                             // For FireFox Compatibility
                             var parentNodeOfMenuItem = allMenuItems[l].parentNode;
                             parentNodeOfMenuItem.removeChild(allMenuItems[l]);
                   }
          }                 
}
}

You can use this function to hide any menu items rendered in the ListViewWebPart toolbar which is used in the list view pages, just call the function and pass the menu item names ( comma separated ) as they appear in the toolbar ignoring the case. Only one exception to that when you need to hide "Create View" which appears twice one in "List Settings" and the other one in the view selector, in order to resolve this conflict just call the function as follows :

hideListViewToolbarItems("settings:create view") or hideListViewToolbarItems("view:create view")
