WSS 3.0 and MOSS 2007 now have a supported extensibility mechanism allowing developers to easily add links to existing menus or Site Settings.

Custom Actions can be used to add new custom functionality to many places in WSS and MOSS. Depending on where the custom action is located determines the user interface of the custom action. For example if you create a custom action for the Site Actions menu the result is a menu item anchored in the control. If you create a Custom Action for the Site Settings page you will see a link.  Creating a custom action for a list's display form toolbar results in a toolbar button. As you can see just from this small list a Custom Action provides a lot of extensibility in WSS and MOSS.

Each custom action exists in a specific location, and depending on that location, can be a part of a group of actions. You can find the Default Custom Action Locations and IDs in Microsoft site.

With a custom action feature, you can:

• Add a new Custom Action Group which can be used to group custom actions in a specific options screen;
• Add a new Custom Action which can be a new option in a settings screen, a new menu item, or a new toolbar button;
• Hide an existing Custom Action whether that action is the result of custom action feature or it belongs to SharePoint's out-of-the-box features.

How to Create a Custom Action Feature

1. Create a new Project in VS 2008.
2. Within the project create the following folder structure
3. Within the MyCustomActions folder, Add a new item and select XML file. Name it as CustomActions.xml
4. Add the following text and make the changes accordingly.

   <?xml version="1.0" encoding="utf-8" ?>
   <Elements xmlns="http://schemas.microsoft.com/sharepoint/">
       <!-- Custom Action Group -->
       <CustomActionGroup
           Id="MyActionGroup"
           Description="This group contains all my custom actions."
           Title="My Action Group"
           Location="Microsoft.SharePoint.SiteSettings"
           Sequence="30" />
   
       <!-- Custom Action in Custom Action Group -->
       <CustomAction
           Id="MyCustomAction"
           Description="This link is a custom action."
           Title="My Custom Action"
           GroupId="MyActionGroup"
           Location="Microsoft.SharePoint.SiteSettings"
           Rights="ManageWeb"
           RequireSiteAdministrator="FALSE"
           Sequence="20">
           <UrlAction Url="~sitecollection/_layouts/MyCustomPage1.aspx" />
       </CustomAction>
   
       <!-- Custom Action in Site Actions Menu -->
       <CustomAction
           Id="MyNewCustomAction"
           Description="This menu item is a new custom action."
           Title="My New Custom Action"
           GroupId="SiteActions"
           Location="Microsoft.SharePoint.StandardMenu"
           ImageUrl="/_layouts/MyActionIcon.jpg"
           Sequence="10">
           <UrlAction Url="~sitecollection/_layouts/MyCustomPage2.aspx" />
       </CustomAction>
   
       <!-- Hide Custom Action -->
       <HideCustomAction
           Id="HideDeleteWeb"
           GroupId="SiteAdministration"
           Location="Microsoft.SharePoint.SiteSettings"
           HideActionId="DeleteWeb" />
   </Elements>
    

   
   



5. Within the MyCustomActions folder, Add a new item and select XML file. Name it as feature.xml



6. Add the following text and make the changes accordingly.
   

   <?xml version="1.0" encoding="utf-8"?>
   
   <Feature  Id="Paste your NEW GUID Here"
   
   
             Title="My Custom Actions"
   
   
             Description="My Custom Actions"
   
   
             Version="12.0.0.0"
   
   
             Scope="Site"
   
   
             xmlns="http://schemas.microsoft.com/sharepoint/">
   
   
     <ElementManifests>
   
   
       <ElementManifest Location="CustomActions.xml" /> 
     </ElementManifests>
   
   
   </Feature>

   
   



7. Build the project using WSPBuilder and deploy the WSP.

Custom Actions really provide us with a great mechanism to place our needed extensions into the menus of WSS and SPS. This post about Custom Actions is a very simple start to what you can do. If you want to know more about Features, check this nice article SharePoint 2007 Deployment: Overview.

Today I restore a site collection from different server to my VM and when I try to update the site Collection Administrators info on the site I received “you need to be a site collection administrator to set this property”. And also I don’t see the Site Settings and others which you normally see under site Action menu.

After a quick google, I found that Site Collection was locked and I need to unlock it. To unlock site collection, Go to central Admin –> Application Management. Click on “Site collection quotas and locks” under “SharePoint site Management”, then select “Not Locked” option.

Hope this post helped someone.

If you are writing web parts either in ASP.NET or SharePoint, you need to understand the events and order of execution.

In this post i am trying to summarize the events and its order

OnInit – Configuration values set using WebBrowsable properties and those in web part task pane are loaded into the web part.
LoadViewState – The view state of the web part is populated over here.
CreateChildControls – All the controls specified are created and added to controls collection. When the page is being rendered for the first time the method generally occurs after the OnLoad() event. In case of postback, it is called before the OnLoad() event. We can make use of EnsureChildControls() - It checks to see if the CreateChildControls method has yet been called, and if it has not, calls it.
OnLoad
User Generated Event – for e.g. button click on the web part.
OnPreRender – Here we can change any of the web part properties before the control output is
drawn.
RenderContents – Html Output is generated.
SaveViewState - View state of the web part is serialized and saved.
Dispose
UnLoad.
