  • ESRI options
  • Microsoft Virtual Earth
what is a web part
What is a Web Part?
  • According to Microsoft, ASP.NET Web Parts controls are an integrated set of controls for creating Web sites that enable end users to modify the content, appearance, and behavior of Web pages directly in a browser.
  • Why use a Web Part?
    • Consistent look and feel
    • Ease of use and reuse
from a developer s perspective what is a web part
From a Developer’s Perspective:What is a Web Part?
  • 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
Web Part Attributes
  • A Web Part-based page allows users to:
    • 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.

SharePoint WebParts
  • In WSS3.0, Web Parts based on ASP.NET 2.0 Web Part infrastructure.
  • In most cases, should develop Web Parts inheriting from System.Web.UI.WebControls.WebParts.WebPart.
  • Microsoft.SharePoint.WebPartPages.WebPart provides the following features:
    • Cross page connections
    • Connections between Web Parts outside of a zone.
    • Client-side connections (Web Part Page Services Component)
    • Data caching infrastructure, including ability to cache database

Operating System
  • No easy way to develop on Windows XP.
  • Free Virtual Hard Drive downloadable from Microsoft at
  • Includes WSS 3.0 SP1 and VS 2008.
  • Expires Sept 20, 2009.
  • About 1.8GB.
wss 3 0 tools vs 2008 extensions

  • Contains VS project templates for Web Parts, site definitions, and SP solution.
  • Available for download from
  • F5 builds and deploys solution, then opens IE.
  • Provides ability to debug code.
  • Possible to create WebADF Web Parts.
  • ArcGIS Server blog provides samples for both 9.2 ( and 9.3 (
  • Limitations:
    • 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.

ESRI 9.3 sample from

arcgis server js api
ArcGIS Server JS API
  • Surprisingly powerful and relatively easy to use in SharePoint.
  • Keep in mind:
    • 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.


    • JS & CSS can be added in different ways. Make sure you test to see if files already exist.
