Step by step procedures to create a Delegate control using Visual Studio 2013 in SharePoint 2013.

 Using the delegate control we can customize the SharePoint site controls without editing the master page by injecting user controls, scripts, css through this special type of control.

We are not customizing the existing (default) delegate control but we are creating our own control loading onto the SharePoint site.

The following code to add a delegate control

<SharePoint:DelegateControl runat="server" AllowMultipleControls="true" ControlId="IDofControl"/>

Some default Delegate controls:

SharePoint 2013:

SuiteLinksDelegate

SuiteBarBrandingDelegate

PromotedActions

 

SharePoint 2010:

AdditionalPageHead

GlobalSiteLink0

GlobalSiteLink1

GlobalSiteLink2

PublishingConsole

QuickLaunchDataSource

SmallSearchInputBox

TopNavigationDataSource.

Follow the Steps to Create a Delegate control in SharePoint 2013 using Visual Studio 2013:

1. Open Visual Studio 2013->File -> New Project, -> Empty Project.

 Confirm SharePoint Site URL for debugging and choose deploy as farm solution.

 

 

2. Add CONTROL TEMPLATES Mapped folder into the project. Right click on the project -> Add -> SharePoint Mapped Folder.

 

 

3. Select CONTROL TEMPLATES

 

 

4.  Now, Right click on the folder -> Add New Item and then select User Control (Farm Solution Only) to add User Control.

 

5. Logic for delegate control. I have just put a text message.

6. Again, Right click on the project -> Add New Item - > Empty Element.

 

Now the solution and project as below

 

By using Delegate controls we can inject a code or control to a SharePoint master page without touching the code of the master page.docx

 

7. Add the following code in Elements.xml file:

 

<Control Id="ControlToShowAlertMessage" Sequence="1"ControlSrc="/_controltemplates/15/ShowAlertMessage.ascx" />

 

Control Id using this we can call in master page.

 

ControlSrc : Path of user control.

 

 

Now build and deploy the project. After deployed successfully, and you deployed in web scope then it will show in Site Feature

 

8. Add call the control in master page by control id 

Just Open master page using SharePoint designer 2013 and Check out and Edit in Advanced mode and paste the following code in the master page.

 

<SharePoint:DelegateControl ControlId="ControlToShowAlertMessage" AllowMultipleControls="true" runat="server"></SharePoint:DelegateControl>

 ControlId is the id of user control given in Elements.xml file.

9. Now check in and publish the master page as a major version, and delegate control will appear:

If you do not want to show message then just deactivate this feature

Go to Site Settings -> Manage Site Features. And then in the Manage Site Features page you can deactivate the feature. The delegate control will not appear.
