Designing InfoPath Forms New features in InfoPath and InfoPath Forms Services 2010 InfoPath Best Practices
Sandboxing Your InfoPath Forms Form Development Tools
In today’s world, most business processes rely on capturing information from the end users and translating it into appropriate and timely actions A majority of these business processes simply start with a form and may use other forms throughout their lifecycle Unfortunately,
in many cases forms are received with inaccurate information, which leads to bad decision making, signifi cant cost, and damage to organizations
SharePoint ships with a great object model that can be used to build sophisticated forms for gathering data and feeding it to the enterprise business processes, such as workfl ow sequences and composite applications The vision behind the product, as an application development platform, however, has always been based on its ability to build powerful enterprise
applications quickly and easily The emphasis on the words easy and quickly in the product’s
vision statement means that there should be an easier way to create, distribute, and manage electronic forms with little or no code
InfoPath 2003 was Microsoft’s fi rst attempt to uniquely position this product to handle the problems in business data collection and presentation needs The main feature of InfoPath
2003 was the ability to author and render XML-based electronic forms with support for custom-defi ned schema InfoPath 2003 native support for XML made it a compelling solution for integration with many backend systems that can understand and communicate in XML
In SharePoint 2003, a form library and its form template were designed to glue the two

products together Collectively, the form library and its template allowed customers to create new
instances of a single form template and translate the fi eld values into column values upon saving the
form, all done within the context of a SharePoint site but fi lled out via the InfoPath 2003 client
Because of some architectural and deployment limitations in InfoPath 2003, this product never
achieved adoption beyond simple departmental solutions that allowed members of small teams to
collect, route, and store data within their own little collaborative sandboxes But, how about the
Enterprise?
Not all users who interact with business processes have access to the InfoPath client application;
neither do they use one particular device, such as their computer, all the time! For example, sales
agents need to take the forms offl ine and use their PDAs and smart phones to fi ll them out, partners
use only their browser to interact with forms, and internal employees may use a combination of the
InfoPath client and browsers to participate in various business processes across the enterprise
When the Offi ce 2007 suite hit the streets, Microsoft introduced a very exciting feature: Forms
Services 2007 — included in the enterprise version of Microsoft Offi ce SharePoint Server 2007
If you are interested in learning about electronic forms integration with Microsoft Offi ce SharePoint 2007, Chapter 14 (by John Holliday) in the book Professional SharePoint 2007 Development (Wrox, 2007), is a great resource.
In a nutshell, Forms Services was all about allowing end users to use their browsers to fi ll out
InfoPath forms and allowing administrators to manage those forms Form Services 2007 was a
great move to help extend the reach of electronic forms by ensuring that electronic forms can render
content for a wide range of users using various client applications and different devices The concept
of content types and their association with form templates, two-way synching between form data
fi elds and columns, and a better deployment model were all among major improvements Microsoft
made to the product at that time
With the power of the SharePoint Server 2010 platform, InfoPath 2010 and Forms Services 2010
represent even more signifi cant improvements over their predecessors Some of the improvements
came from the core platform itself and some were made available in each product
InfoPath 2010, available in the Professional Plus volume license SKU, is a form creation and
data-gathering tool that ships with the Microsoft Offi ce 2010 package If we consider InfoPath 2003
Service Pack 1 as a major iteration in the product’s lifecycle, then InfoPath, in its fourth iteration
with the 2010 release, has evolved way beyond the product that was released back in August 2003
InfoPath 2010 is the most compelling release to date and is the quickest way to have a common form
rendition in the browser as well as in rich and offl ine clients
Once you install InfoPath 2010, the fi rst thing that you may notice is that InfoPath 2010 comes with
two fl avors: InfoPath Designer and InfoPath Filler InfoPath Designer 2010 is the primary tool used
by designers to create and design the forms with easy-to-use features based on pre-built templates
and baked-in functionalities As the name implies, InfoPath Filler 2010 comes with a Fluent UI,
which provides a much improved and yet simpler end user experience for fi lling out forms
Trang 3The following list provides a sneak peek of some of the new features introduced in InfoPath 2010 and InfoPath Form Services 2010:
Richer browser forms with shorter load time
The capability to handle more requests per second
The capability to customize SharePoint list forms
A brand-new InfoPath Form web part
Equal rendition across the major browsers Compliant browser forms (WCAG 2.0, XHTML 1.0, and strict CSS)
Integration with Business Connectivity Services (BCS)
Ability to query REST web services/ SharePoint REST APIs
Native offl ine integration with SharePoint through SharePoint Workspace 2010 client
New controls like the People/Group Picker, Date Time Picker, and Picture button
On-premises or multi-tenant hosting support (i.e., SharePoint online)
Ability to script various operations using PowerShell, backup, and restore
Seamless integration with new Health Rule Defi nitions
Enterprise forms is a broad topic that could make up several chapters, if not its own book
However, after reading this chapter, you will have a good understanding of how to leverage InfoPath in SharePoint to rapidly design and create forms used in enterprise management processes across your organization
And with that, it is time to get started
INTRODUCING THE TRAINING MANAGEMENT APPLICATION
In this chapter, you’ll use an example of a Training Management application at a fi ctitious company, Adventure Works, which illustrates some of the new capabilities of InfoPath 2010 and Forms Services 2010 First, take a look at how this application works from the user’s perspective
The Human Resources (HR) department at Adventure Works uses SharePoint and InfoPath to implement a training-course system You can think of the Training Management application as a set
of three use cases as follows:
New training creation use case Training registration use case Increment stat counter use case
As illustrated in Figure 9-1, Adventure Works staff can perform various activities in this application For example, the training coordinator can create trainings and add them to a SharePoint list named Trainings This list will be customized and enhanced by InfoPath 2010 to facilitate the training creation use case

Also, the Human Resources department at Adventure Works allows its employees to register for
a training opportunity The training registration form is designed in InfoPath and hosted inside
the new InfoPath Form web part on a web part page named Trainings Dashboard The training
registration form must be rendered in a typical desktop web browser and in browsers on handheld
or mobile devices
Once a training request is fi lled out and saved, the result is stored in a form library named
Registrations, and an event handler associated with the Registrations form library fi res and updates
a counter in another custom SharePoint list, named Stats The Stats list is hidden from employees
so that its content can’t be modifi ed and it does not clutter navigation At the end, the registration
form is connected to the Stats list through the web part connections framework in SharePoint to
demonstrate a simple form-driven mashup scenario
As you may notice, the primary forms in driving the business process just described are all
electronic forms and implemented in InfoPath 2010 The following diagram demonstrates a high
level overview of the Training Management application

CUSTOMIZING SHAREPOINT LIST FORMS
In Windows SharePoint Services 3.0, list forms were regular ASP.NET pages serving as the visual
interfaces to add an item to, or edit or display an item in, that list Typically, list forms were
defi ned in the list template and instantiated upon the creation of a new list instance Although
Trang 5there are several ways to replace the out-of-the-box list forms (DispForm.aspx, EditForm.aspx, and NewForm.aspx) with custom ASPX pages, as described in the following list, each approach introduces its own challenges:
to modify the layout of list forms and add custom business logic For example, you could create a new NewForm.aspx form from scratch This approach introduces a very limited
customizability that limits you to using HTML, JavaScript, and Extensible Stylesheet Language (XSL) only Additionally, customizing list forms using SharePoint Designer 2007 results in inserting a fairly big chunk of XSL into the HTML markup of the form, which makes it even harder to maintain!
New forms via a browser to add business logic for the inserting and editing of list item data The problem with this approach is that Microsoft clearly states that it is not supported, meaning that if something breaks you’ll have to remove the web part and leave the default List Form web part as the only web part on the page This is certainly not a solution that you can always rely on either
the other two, because you can use all your ASP.NET coding skill sets and deploy the list forms in a much cleaner way However, you cannot leverage this approach for the existing content types or lists that are not yours You must add to this the extra code that you would have to write to handle the CRUD (create, read, update, and delete) operations that your custom UI requires when interacting with lists, such as wrapping your calls to Update()
methods in a try/catch block and trap for exceptions like concurrency violations and so on
One of the exciting features in InfoPath 2010 is the ability to extend or enhance the forms used
by SharePoint lists for creating, editing, or showing list items Today, you can modify list forms layouts, set validation rules, or create additional views using little or no code When you are fi nished modifying the list forms, refl ecting your changes back to SharePoint is just a matter of using the one-click publishing capability that comes out of the box with the list form
In this section, you will explore some of the new functionalities of InfoPath 2010 used to customize SharePoint list forms in the context of a Training Management application, which you will build throughout the chapter
Creating the Trainings List
Before diving into customizing the Trainings list forms using InfoPath, you need to create the SharePoint list and add the required fi elds to it Business requirements of the Training Management application dictate that the training coordinator be able to create new training opportunities by selecting Add New Item in the Trainings list This list resides on the Human Resources website and requires the following information:
Title: A title for the training opportunity Code: A code that uniquely identifi es the training (unique eight-character fi xed) Description: The description of the training
