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?
