– Consistent look and feel
– Ease of use and reuse

• Server-side control running inside
context of Web Part pages within
ASP.NET application or Windows
SharePoint Services site.
• 2 types of Web Parts:
• ASP.NET 2.0:
• Built on top of the ASP.NET Web Part
infrastructure
• Have a dependency on System.Web.dll
• Can be used in SharePoint and other
types of web sites, making them much
more flexible
• SharePoint:
• Older and have a dependency on
Microsoft.SharePoint.dll
• Can only be used in SharePoint web
sites
Web Part Attributes
– Add/remove Web Parts from page.
– Move Web Parts on page.

•Personalization requires database.
Default is SQL Server Express 2005, but
a different database can be specified in
configuration file.

Web Part infrastructure.
• In most cases, should develop Web Parts
inheriting from
System.Web.UI.WebControls.WebParts.WebPart.

ESRI OPTIONS
WebADF
FIRMWIDE
SERVICES
– 64-bit MOSS 2007 requires IIS application
pools to run in pure 64-bit mode, which means
that 32-bit applications, including the WebADF,
will not work. (Rex Hansen, ESRI,

– Potential for additional ArcGIS Server license
depending on network set-up.

•Possible to create WebADF Web Parts.
•ArcGIS Server blog provides samples for
both 9.2 (http://tinyurl.com/baaajs) and
9.3 (http://tinyurl.com/djj3oa).

ArcGIS Server JS API

– Potential for multiple web parts, including
identical web parts, on a single web page.
Affects element names.
– Use the _spBodyOnLoadFunctionNames array
to add JS functions to the window.onload
event.
_spBodyOnLoadFunctionNames.push('Indy.Web
Controls.JSAPI.init()');";
– JS & CSS can be added in different ways. Make
sure you test to see if files already exist.

•Surprisingly powerful and relatively easy
to use in SharePoint.
