Dynamic Picklist - Sub Industry based on Industry aka Cascading Picklists in Microsoft CRM

This contains sample code that demonstrates how to implement dynamic picklists on a custom entity. It creates a custom entity named “Dynamic Picklist Test” that contains Industry and Sub-Industry picklist fields. When a value for Industry is selected, the values in the Sub-Industry picklist field are filtered. If there are no sub-industries for an industry, the Sub-Industry field is disabled.

See how the Sub-Industry Field isn't even an option. :-)

The pick list for the accountants.

The picklist for the consulting industry.
