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 AttributesWeb 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 WebPartsSharePoint 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

WebADFWebADF

•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).

•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, http://tinyurl.com/bfcnwf)

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

ArcGIS Server JS APIArcGIS 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.

_spBodyOnLoadFunctionNames.push('Indy.WebControls.JSAPI.init()');";

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