SharePoint 2013 and SharePoint 2010 Delegate Controls

SharePoint Delegate control is a mechanism that we can inject a code or control to the SharePoint Master page with out touching any any code in the SharePoint Master page.

is a container type control which can holds child controls on it

This is the simplest explanation for the SharePoint delegate controls but this also may confuse to you. So let me further simplify.

SharePoint Master Page design in a way that leaving place holders(Not a place holder really but for get an idea) to some controls (Delegate Controls) that has a machinist to inject.

Assume this is our SharePoint Master page.


The Red Rectangle (SmallSearchInputBox) is a delegate control. It means the textbox and other functionalities in that search box not written in the  master page. Master page just have a place holder with id SmallSearchInputBox and which is going to dynamically replace by search box in the run time.

Master Page code is just look like this.


There are few delegate controls defined in the SharePoint Master page.

Why We need Delegate Controls

1. We can inject controls to master page with out changing any code. For an example you need a custom control to put in the place of small search box. So you can create a control and activate the control using a feature.Then control will display in the place of search box but good thing is you didn’t touch any master page code.

2.You can customize the master page delegate controls dynamically  by user permissions,URLs , or any other custom rule

3. Recently we have a problem that we need to include some custom user validation for each and every SharePoint page. So we finally decided to  put that code in AdditionalPageHead so it will get apply to all pages and we need to simply create a control to inject to the delegate control.

SharePoint 2010 and SharePoint 2013


  • This is top most delegate control in the master page. this delegate allows multiple controls. You can use this delegate to inject JavaScript to SharePoint master , inject custom logic and etc. page Good thing about the AdditionalPageHead control is it is lie between the html head tag. therefore it is not a control with interface. You can specify a control which only have a code to do what ever you need in onLoad event.


  • Global navigation is top most visible control collection. You can add your delegate controls to this location as well.


  • this delegate control handles social icons in the site. you can change this two icons by creating delegate control



  • SharePoint dashboard control handles using this  delegate.



  • you can change this menu (may be add more items to it) using this delegate control.



  • This delegate control holds the server ribbon. normally we didn't use it for customize the server ribbon. of cause if you want you can..


  • This delegate use for default top navigation. You can override the data source by adding a custom data source.


  • This control handles small search control in the master page.



  • This delegate control provides mechanism to override left side panel. So you can  create your own data source and set it as a Quick launch data source with out changing the master page.


  • Tree view is the other navigation apart from quick launch and top link. So you can change tree view’s default data source by providing custom data source to this delegate.

New Delegate controls in SharePoint 2013


  • This delegate handles these links in SharePoint 2013. so if you want to add a another link or some other component this is the delegate you need to use.



  • This delegate care about top left site logo and text. If you are interested in any other you can put it in here.



  • You can add controls in between Share and Follow. This holds empty controllers by default.

How to use SharePoint Emulator to test SharePoint list creation,Update

Open the visual studio 2012 and add empty SharePoint project.


Then create the project as farm solution by giving the testing SharePoint server URL (you can give sandbox solution as per your requirement)


Then I'm going to add a feature ; which is going to create a SharePoint list in feature activation.


(adding a feature receiver to the feature)


Now I'm going to add a class (SPController.cs) which is used in Feature Activation event for creating the list in the SharePoint. SPController class having a method called AddListSample() that is use for create a list in the SharePoint.

public class SPController
public void AddListSample(String siteURL, String listName, String description)
using (SPSite site = new SPSite(siteURL))
using (SPWeb web = site.OpenWeb())
Guid listguide = web.Lists.Add(listName, description, SPListTemplateType.GenericList);
SPList list = web.Lists[listguide];

list.Fields.Add("CustomerName", SPFieldType.Text, true);
list.Fields.Add("DOB", SPFieldType.DateTime, false);


Now we are adding the code to Feature to create the list.

public override void FeatureInstalled(SPFeatureReceiverProperties properties)
SPController spcontroller = new SPController();
spcontroller.AddListSample(SPContext.Current.Site.Url, "SampleList", "List Description");

Now we are going to test our code using SharePoint simulator.

For that we need to create a Test Project First (Framework 3.5)


Then we need to create a test class for test SPContollerClass. So im adding SPControllerTest Class to the test Project.



Before coding we need to install SharePoint Simulator uisng NuGet Manager. (This will download fake dlls for the  emulation purpose)



Now you are going to test the AddListSample Method.


Note: By using Emulation.Mode.Enabled this code will test in the Emulated SharePoint environment.

You can go to Test Menu and can Run or Debug the code.



Test result will display on left side of the screen. It will show failed test as well as Passed ones.

Result StackTrace

This error occurred to me when i try to test a SharePoint emulator with a test project.I tried in many ways and it is a simple code; but i wonder why it is  giving this error. i but the dlls to bin and did various things but nothing worked for me. then what i did was

1. First Uninstall the existing emulator from the project (By navigating to NuGet Manger).


2. Then change the Test Project Framework to 3.5 and reinstall the Sharepoint.Emulator using NuGet manager.

Then it worked.

Note: after installing Sharepoint.Emulator in 3.5 i again change the framework to 4.0. and the project still works.
