How to put custom user control on page layout

Question

How can I add a custom user control to a page layout?

I have some custom user control developed. I want to place it in a custom page layout. So it will be in every page instance of that layout.

Answer 1

First create your User Control and publish is to SharePoint.
Then you register a tag for your control

<%@ Register Tagprefix="MyControls" 
    Namespace="KM.MyControls.MyControl" 
    Assembly="KM.MyControls, Version=1.0.0.0, Culture=neutral, PublicKeyToken=<Your token>" %>

Then you can reference your User Control

<MyControls:MyUserControl runat="server"/>

Answer 2

Make sure you put the user control into a subdirectory of {SharePointRoot}/Templates/ControlTemplates

Put a Register element at the top of you page-layout

<%@ Register TagPrefix="MyOwnPrefix" TagName="MyUserControl" Src="~/_controltemplates/MyProjectName/UserControl.ascx" %>

and the refer to it where you need it like:

<MyOwnPrefix:MyUserControl runat="server" id="userControl" />
