SharePoint 2010 developer interview questions

Q. How does Client object model
works?

Ans.

When we use SharePoint client API’s to perform a specific task, the SharePoint Foundation 2010 managed
client object model bundles up these uses of the API into XML and sends it to the server that runs SharePoint
Foundation. The server receives this reque
st, and makes appropriate calls into the object model on the server,
collects the responses, forms them into JavaScript Object Notation (JSON), and sends that JSON back to the
SharePoint Foundation 2010 managed client object model. The client object model
parses the JSON and presents
the results to the application as .NET Framework objects (or ECMAScript objects for ECMAScript).

Q. How many types of Client Object model extension are available in 2010 and when would you use one or the
other.

Ans.

To develop
rich client side solutions, three set of client
-
side APIs has been introduced in the
Microsoft.SharePoint.Client namespace. The three APIs are targeted for three different types of clients.

1. .net Managed applications


These are used when we have to crea
te console applications or window
applications, web applications which are not running inside SharePoint Contex.

2. For Silverlight applications

3. ECMAScript


It is a client object model extension for using with JavaScript or JScript. This is used for cr
eating
applications which are hosted inside SharePoint. For example, web part deployed in SharePoint site can use this
JavaScript API for accessing SharePoint from browser using JavaScript.

Q. What is difference between Load() and LoadQuery() methods ?

Ans
.

Load method populates the client object directly with what it gets data from the server i.e. a collection object
like ListItemCollection etc. but LoadQuery returns the data as a completely new collection in


IEnumerable format.
Other major difference is
that the Collections that you load using the
Load
() method are eligible for garbage
collection only when the client context variable itself goes out of scope where as, in


these collections go out of
scope at the end of


IEnumerable<List>
list.

Q. How can
you write efficient and better performing client object applications ?

Ans.
You can always use Lambda expressions in your queries to return only specific properties that will be used in
your block. You can also use LoadQuery() method and specify multiple l
evels of properties to load for e.g. while
returning specific properties of the lists using LoadQuery(), you can also specify the fields to return from each list
to optimize the data access.

Q. What are the Authentication methods for your client object
model application ?

Ans.

Basically there are three (3) authentication options you can use when you’re working with the Client Object
Model in SharePoint 2010:

* Anonymous

* Default

* FormsAuthentication

You can specify clientContext.Authentication = Anonym
ous
\
Default
\
FormsAuthentication, If you do not choose an
authentication method in your code, the application will default to using the client’s Windows Credentials
(DefaultCredentials).

Q. How do you access ECMAScript object model API’s ?

Ans.

The ECMAScr
ipt library is available in a number of JS files in the LAYOUTS folder. The main file among number
of .js files is SP.js. When you include this file in the APSX page using a ScriptLink control, all other required JS files
are loaded automatically. By linki
ng SP.js to your page, the SP namespace gets registered. SP is the SharePoint
namespace that contains all objects. For debugging purposes every js file also has a ‘debug’ equivalent in the same
folder.


Q. What is the purpose of calling clientContext.Execu
teQuery() ?

Ans.

ExecuteQuery gives you the option to minimize the number of roundtrips to the server from your client code.
All the components loaded into the clientcontext are executed in one go.

Q. Why would you use LINQ over CAML for data retrieval?

An
s.
Unlike CAML, with LINQ to SharePoint provider, you are working with strongly typed list item objects. For
example, an item in the Announcements list is an object of type Announcement and an item on a Tasks list is an
object of type Task. You can then en
umerate the objects and get the properties for your use. Also, you can use
LINQ syntax and the LINQ keywords built into C# and VB for LINQ queries.

Q. Can we use our custom master page with the application pages in SharePoint 2010 ?

Ans.
With 2010, you can

now set whether the pages under _Layouts use the same Master Page as the rest of your
site. You can enable or disable this functionality through the web application settings in Central Administration.
This however, is not applicable to your custom applica
tion pages. If you want your custom applictaion page to
inherit the site master page you must derive it from Microsoft.SharePoint.WebControls.LayoutsPageBase class.

Q. What are WebTemplates and Site Definitions ?

Ans.

Site definitions consist primarily of
multiple XML and ASPX files stored on a front
-
end Web server in folders
under the %ProgramFiles%
\
Common Files
\
Microsoft Shared
\
web server extensions
\
14
\
TEMPLATE
\
SiteTemplates
directory.

Custom Web templates on the other hand, are stored in the database, an
d are created using an existing site, with
or without its specific content, as a model. This provides a means for reusing sites that you have customized.In
some ways, Web templates continue to depend, throughout their lifecycle, on the site definition that

is their
ultimate foundation.

Q. How do you write to SharePoint ULS logs in 2010 ?

Ans.

In SharePoint Foundation, ULS exposes configurable settings in two ways, through the


Object model and
Windows PowerShell cmdlets. For writing to SharePoint ULS logs
developers can can use Diagnostics Service, which
will make the customized categories viewable in the administrative UI for our errors.

or they can use the number of cmdlets available for accessing ULS logs using powershell. Some of the cmdlets are
Get
-
SPD
iagnosticConfig ,Get
-
SPLogEvent etc.


Q. What does CMDUI.XML contain?

Ans.

The definitions for the out
-
of
-
the
-
box ribbon elements are split across several files in the SharePoint root,
with TEMPLATE
\
GLOBAL
\
XML
\
CMDUI.XML being the main one.

Q.

What has Changed in SharePoint 2010 Object model?

Ans.
Microsoft has replaced the “12 hive” structure that we had in SharePoint 2007 with “14 Hive” structure in
2010.

It has apparently added four new folders to its hive.

The Folders are :

* Policy

* UserC
ode

* WebClients

* WebServices

Q. How would you deploy WebPart Using Windows PowerShell?

Ans.
At the Windows PowerShell command prompt (PS C:
\
>), type the below command :

Install
-
SPWebPartPack
-
LiteralPath “FullPathofCabFile”
-
Name “Nameof WebPart”

Q. How

would you re
-
deploy the old custom solutions in SharePoint 2010.What Changes are needed to the old
Solution files.

Ans.

SharePoint 2010 object model contains many changes and enhancements, but our custom code will still
compile and, will run as expected.
You should however, rewrite and recompile any code that refers to files and
resources in “12 hive”.

For Details See :

SharePoint Object Model


Backward Compatibility

Q. How would you add a link in the Ribbon?

Ans.

You can add any link or Custom Action und
er any of the existing tabs of the ribbon or can create a new a new
tab and place your links under it.

Q. What does CMDUI.XML contain?

Ans.
The definitions for the out
-
of
-
the
-
box ribbon elements are split across several files in the SharePoint root,
with
TEMPLATE
\
GLOBAL
\
XML
\
CMDUI.XML being the main one.

Q. What are the Disadvantages of Using LINQ in your Code?

Ans.

LINQ translates the LINQ queries into Collaborative Application Markup Language (CAML) queries thus adding
an extra step for retrieving the ite
ms.

Q. What is different with SharePoint 2010 workflows ?

Ans.

Some of the additions in workflow model are :

1. SharePoint 2010 workflows are build upon the the workflow engine provide .Net Framework 3.5.

2. In addition to the SharePoint lists we can now c
reate workflows for SharePoint sites as well.

5


3. SharePoint Designer 2010 also has a new graphical workflow designer for designing workflows and deploying
them directly to SharePoint.

4. Another Improvement in SharePoint Designer 2010 is that it now allows

you to edit the out
-
of
-
the
-
box
workflows that come with SharePoint.

Q. How does Ribbon works ?

Ans.

A file called CMDUI.XML stays at the web front end which contains the Out
-
of
-
Box site wide Ribbon
implementation i.e. all the Ribbon UI for the entire site
. In addition to this you have a CustomAction for each
ribbon component. These CustomActions have CommandUIExtentions block which has CommandUIDefinitions and
CommandUIHandlers which make up the activity of the ribbon component. So, when the ribbon is load
ed the
CommandUIDefinition merges with Out
-
of
-
Box definition in the CMDUI.XML

Q. How will you use WebParts or other solutions Created in SharePoint 2007 in SharePoint 2010 ?

Ans.

In SharePoint 2010 the 12 hive is now replaced by 14 hive, So we will rewrite

and recompile any code that
refers to files and resources in “12″ hive. In addition to we must recompile custom code written for Windows
SharePoint Services 3.0 and Office SharePoint Server 2007 that does not run on IIS.

Q. What is the advantage in using
Windows PowerShell over stsadm in SharePoint 2010 ?

Ans.
Unlike stsadm, which accept and return text, Windows PowerShell is built on the Microsoft .NET Framework
and accepts and returns .NET Framework objects.Windows PowerShell also gives you access to the

file system on
the computer and enables you to access other data stores, such as the registry and the digital signature certificate
stores etc..

Q. What is REST ? How is it used in SharePoint 2010 ?

Ans.

REST (Representational State transfer) is a protoco
l (powered by ADO.NET services) which is used for getting
data out of sharepoint via Url. It is mostly used to access data from sharepoint even when you are not in the
sharepoint context.

Q. What datatype is retured by REST ?

Ans.

REST does not return an o
bject of type SharePoint Site
\
List. Instead, it returns an XML output.

Q. What is a workflow?

Ans.

Workflows are the way an organization functions, a series of actions that correspond to a work process, such
as the process for purchase orders.SharePoint 20
10 helps you automate these workflows, thereby increasing the
efficiency and productivity of the organization.

Q. What are the types of workflow that you can design in SharePoint 2010.

Ans.

you can design List Workflows, Reusable List Workflows and Site wo
rkflows using SharePoint designer 2010.

Q. What Reusable List Workflows and Site workflows ?

Ans.

6


Reusable List Workflows
-

You can create a reusable list workflow (reusable workflow) in the top
-
level site in the site collection, and that
workflow can be
made globally reusable


meaning that the workflow can be associated to any list, library, or
content type in the site collection. You can also create a reusable workflow in any subsite in the site collection; this
workflow is available for reuse in that p
articular subsite.

Site workflows
-

A site workflow is associated to a site


not to a list, library, or content type. So unlike most
workflows, a site workflow is not running on a specific list item. Because of this, many of the actions that are
available

for items not available for site workflows.

Q. Can you modify the Out
-
of
-
Box workflows in SharePoint 2010 ?

Ans.

In SharePoint 2010, you have an option to customize the Out
-
of
-
Box workflows. The four most popular
workflows in SharePoint Server 2007


the Approval, Collect Feedback, Collect Signatures, Publishing Approval
workflows


have been completely rebuilt as d
eclarative reusable workflows, meaning that they are now fully
customizable in SharePoint Designer 2010.

Q. What are events, actions, conditions and steps?

Ans.

Lets look at this one by one.

Events
-

An event is what starts or initiates a workflow. Events
can also be used to manage the timing of actions
within a workflow, such as waiting for the status of an item to change. There are three events that can start a
workflow:

* An item is created.

* An item is changed.

* A workflow participant clicks a start b
utton on the SharePoint site.


Actions


An action is the most basic unit of work in a workflow. SharePoint Designer 2010 provides a set of ready
-
made, reusable actions for you to incorporate into your workflow.

For example, your workflow can:

* Create,
copy, change, or delete list items (including documents).

* Check items in or out.

* Send an e
-
mail message.

Conditions
-

When you design a workflow, you can use the workflow editor to create rules that apply conditional
logic to SharePoint sites, lists, i
tems and content types. A rule establishes a condition where the workflow
performs the associated action only if that condition is true. For example, you can create a rule where the
workflow sends a reviewer an e
-
mail message only if an item is created by
a specific person.

Q. What are Parallel and Serial actions ?

Ans.

When you have more than one action associated with a condition, the actions can be set up to run at the
same time (parallel) or one after another (serial), the default.

Q. What are the Types

of forms associated with the workflow ?

7


Ans.

With SharePoint Designer 2010, you can create three types of workflow forms:

Initiation form


An initiation form gathers information from the workflow participant when they start the
workflow. It is automatica
lly generated when you create the workflow in SharePoint Designer 2010. Initiation
forms are displayed to users when they manually start a workflow on a given SharePoint item. With an initiation
form, users can specify additional parameters or information
about the workflow as it applies to the given
SharePoint item.


Task form


A custom task form allows workflow participants to interact with tasks in the Tasks list specified for
the workflow. With the Custom Task Wizard, you can easily create custom form
fields and add them to a custom
task form. When you finish designing the workflow, SharePoint Designer 2010 automatically generates the
InfoPath or ASP.NET forms for your custom tasks.

Reusable workflow


association form



A reusable workflow, by default,

only provides the fields common to all
items, such as Created and Modified by. This is because a reusable workflow isn’t by default associated with a list,
library, or content type. An association form enables you to associate fields with a reusable workf
low so that the
fields will be available when you design and run the workflow.

Q. When are these forms get created ? And how do you customize it ?

Ans.

SharePoint Designer 2010 automatically generates the forms, but you can customize them by going to the
s
ettings page for the workflow, in the Forms section, click the form you want to customize. Workflow forms are
either InfoPath or ASP.NET pages. They are stored on the SharePoint site with the workflow source files.
