The grid I'm working with is used for time reporting.

I have two ComboBox columns.  Column A is the project, column B is the project step.  So until they select a project in column A's drop down, there should be no values in column B's drop down.  Once they selet a project in column A's drop down, the drop down in column B should be populated with the steps related to that project.

What's the best way to achieve this?  For column B I can bind to a DomainDataSource (I'm using RIA services) and apply a filter to it and call a load, but how do I capture the event of a selection in column A, and get to the selected value?
