At the first meeting of the OTEC group in Guangzhou, I gave a keynote speech titled "Developing and deploying web components based on SharePoint Portal Server 2003" and made a demo, now, you can download the source ppt and demo programs.
In this demo, I introduced most of the features in webpart, including:
Renderwebpart in webpart
Custom Attributes
Use properties with a drop-down menu
Custom attribute Selector
Use child Widgets
Custom context menu
Custom toolpart
Use custom attributes in custom toolpart
Use preview View
Design-Time View
Provide icons for webpart
Use resource files
It is not found in the demo, but has introduced features in the PPT, and provides download of the demo, as shown below:
Create a connectable webpart
Define context menu
Create a webpart for asynchronous calling
For webpart debugging, a video link "How to debug webpart in one step" is provided.
Hope to help you
