This snippet of code allows you to create a hidden SharePoint Provider Web Part that is used to pass properties from the current user’s profile to consumer web parts.
All of the User Profile properties are populated into a drop down list.
When a value is picked, the current user’s property value is displayed. You also have the option to override this value.
You can then connect this web part to a consumer web part. In this case, I have created a web part that filters a list based on a certain criteria. One of the query parameters is a user profile property.
