Q) How can we use custom controls in SharePoint?
Step
1:-
Create the custom control by inheriting from the ‘WebControl’ class and
override the ‘RenderContents’ method with your implementation. In the below
code snippet we are just writing the site title and site URL to the browser.
using
System.Web.UI;
using
System.Web.UI.WebControls;
using
Microsoft.SharePoint;
namespace
NameSpaceCustomControl
{
public class CustomControl1 :
WebControl
{
protected
override void RenderContents(HtmlTextWriter output)
{
SPWeb rootSite = SPContext.Current.Web;
output.Write("The Site
title is " + rootSite.Title);
output.Write("<br/>");
output.Write("The URL of
the site is " + rootSite.Url);
}
}
}
Step
2 : Compile the custom control class and generate the DLL
from the same. Once the compiled DLL is generated, register the same in GAC.
Step
3: Refer the custom control assembly in your ASPX page
using the register
attribute. Please note to specify the public key token
of the GAC.
<%@ Register
Assembly="CustomControl,Version=1.0.0.0,Culture=neutral,PublicKeyToken=4adae03f3c0d5b8e"
Namespace="NameSpaceCustomControl"
TagPrefix="CustomSitePages" %>
Specify the custom control with a proper unique ID.
<CustomSitePages:CustomControl1 ID="cc1"
runat="server" />
Below is the complete code of the page.
<%@ Page Language="C#"
MasterPageFile="~masterurl/default.master"
meta:progid="SharePoint.WebPartPage.Document"%>
<%@ Register Assembly="CustomControl,Version=1.0.0.0,Culture=neutral,PublicKeyToken=4adae03f3c0d5b8e"
Namespace="NameSpaceCustomControl"
TagPrefix="CustomSitePages" %>
<asp:Content runat="server"
ContentPlaceHolderID="PlaceHolderMain">
<h2>Hi this is a JaganInfo Site Page</h2>
<CustomSitePages:CustomControl1 ID="cc1"
runat="server" />
</asp:Content>

Q ) What
are WebParts and how does it interact with SharePoint ?
It helps to build reusable components which can
customized and personalized according to business user. We can either make our
own webpart or we can reuse the existing one's from SharePoint itself.
Web Parts are the fundamental building blocks for Share
Point user interface, and with them we can build and integrate many different
types of applications.In share point also be create custom web part using .oscx
control
Steps
create custom web part
1. create web
part project copied .oscx control and build application.place .dll file in GAC
.reset IIS.
2. go 12 hive
_layout folder create folder past your .oscx control
3. go inetpub
->wwwroot->wss->open Your site ->web con fig->create safe
control write assembly information of web part application
4. open
sharepoint site ->site action-site editing->Galleries ->web
part->new Add your web part.
Following
few WebParts are available in WSS 3.0
Data
View Web Part : Displays data with rich design support
through Microsoft SharePoint Designer.
List
View Web Part : Helps us to display list content for any
list in the SharePoint site.
Image
Web Part : Helps us to display image files.
Content
Editor Web Part : Use this to display static HTML content
using a WYSIWYG editor or to link to a text file.
Members
Web Part : Helps us to display members of the site.
Page
Viewer Web Part: Displays web page in an Iframe.
WebPart is nothing but a simple class which inherits
from System.Web.UI.WebControls.WebParts.
In other words you can say WebPart is kind of a
WebControl which can be deployed in a WebPartZoneControl.
------------------
Q ) WebPart
life cycle events
OnInit
:
This is the initialization event and is the first event to occur.
OnLoad
:
The load event.
CreateChildControls
:
When any child controls are added to a
composite control this event fires.
EnsureChildControls
:
This event makes sure that ‘CreateChildControls’
fires.
OnPreRender
:
This fires just before the render
event.Page.
PreRenderComplete
:
When all controls have executed the
‘OnPreRender’ event this event fires.
Render
:
Render the full control.
RenderContents
:
Renders the contents of the control
only.
Steps
to create a WebPart in SharePoint
Step 1 : Create the Webpart
Step 2 : Copy the compile DLL to the virtual directory
in the BIN folder.
Step 3 : Make
entry of the WebPart in to web.config file.
Step 4 : Add it to the WebPart gallery
Step 5 : Add the WebPart to site pages.
Step 6 : View
the WebPart
---------------------------------------------------------
Q) Workflows
:
While workflow associations are often created directly
on lists and document libraries, a workflow association can also be created on
a content type that exists within the Content Type Gallery for the current site
or content types defined within a list.
It can be applied
* At the
level of a list (or document library)
* At the
level of a content type defined at site scope
* At the level of a site ( Sharepoint 2010 )
What are the ways to initiate the workflow ?
* Automatic
(on item added or item deleted)
* Manual
(standard WSS UI interface)
* Manual
(Custom UI Interface)
*
Programatically through custom code
Types
of input forms in Workflows
Can create four different types of input forms
including
an
association form,
an
initiation form,
a
modification form, and
a task
edit form.
Note
that these forms are optional when you create a workflow template.
Different
types of Workflow
There are two basics type of workflow Sequential
Workflow and State machines workflow.
A sequential workflow has clear start and finish
boundaries. Workflow controls execution in Sequential workflow. In sequential
execution, one task is executed after other. Sequential workflow is more rigid
in format and execution path has a determistic nature.
A State machine workflow is more dynamic in nature.
Workflow has states and the state waits for events to help it move to next
state. In State machine execution path is undetermestic nature.
Different
stages of SharePoint workflow life cycle
There are four stage in the sharepoint workflow cycle
associate, initiate, modify and complete.
Associate
: As said workflows in sharepoint are always talked in
context with a content type.
So the first step is to associate a workflow with a
content type like list or a document.
Initiate
: The second step is to initiate the workflow instance.
Work flows are nothing but classes finally so a workflow instance needs to be
created to start the work flow in action.
Modify
: Later the workflow instance is modified as per the
workflow stages.
Complete
: Finally the workflow object is terminated.
How
the workflow will be executed ?
• Administrator creates the initiates the task. The
task is assigned to the reviewer.
• The reviewer then reviews the task, makes his
comments and makes the task in progress. Once he makes the task in progress
it’s automatically assigned to the acceptor.
• Acceptor finally does the complete review and closes
the task.
