In the following example, the Web Part, Get More Information, tracks the requester's name and address, so it can be retrieved the next time the user accesses the dashboard. It stores these values in custom properties using the State Management service. For each property, the Web Part specifies the namespace and name in addition to the value for each property.

Later, the Web Part can retrieve this state through the Properties collection.

The following is the content of the Web Part, Purchase Car.

**Note   **The Web Part uses the string 'varPart_WPQ_' to reference itself.
