• Site Definitions are the foundations on which all sites and user templates are built.
  
• Site Definition is collection ox XML and .aspx file.
  
• Site Definitions are predefined components needs to be included when a site was created in SharePoint server.

2. Copy a Site Definition and change it in Visual Studio: We can make copy an existing site definition and modify it in visual studio to create new site definition.

 

• The configuration of this site definitions are defined in XML file which is available in
  

  C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\1033\XML folder.
  

   

• In the file system these definitions are available in C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\Site Templates.
  
  • Each of these site definitions consists a XML folder and a Home page (default.aspx).

3. Open the folder Tiger
   
4. Search for default.aspx
   
5. Open default.aspx in notepad.
   
6. Modify code. Here we need to add code for site definition.

1. Register new site definition to SharePoint.
   
2. Open the folder
   

    

   C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\1033\XML
   

3. Copy the file WEBTEMP.XML and save it as WEBTEMPTIGER.xml. here make a note that , we need to append name of folder which we created in step 2 ( in this case it is tiger) to WEBTEMP. So here name would be WEBTEMPTIGER.xml
   
4. Open WEBTEMPTIGER.XML in notepad and replace it with following content.
   

 

 

<?xml version=”1.0″ encoding=”utf-8″?>

<!– _lcid=”1033″ _version=”12.0.4518″ _dal=”1″ –>

<!– _LocalBinding –>

<Templates xmlns:ows=”Microsoft SharePoint”>

 

<Template Name=”TIGER” ID=”10009″>

 

<Configuration ID=”1″ Title=”Tiger Definition” Hidden=”FALSE” ImageUrl=”/_layouts/images/Eye.GIF” Description=”Tiger Site.” DisplayCategory=”Custom” AllowGlobalFeatureAssociations=”False” > </Configuration>

 

</Template>

</Templates>

 

Make sure here ID should be greater than 10000. It must not collide with id of any other Site Definition.

 

1. Restart IIS. Go to Start->Run->IISRESET
   
2. Now you would be able to see this Site Definition inside Custom category.
   

 

 

 

Happy Coding
