In order to access the DataList
using grid events, you can use the FindControl method. You can also use the DataList events, like DataBinding or Load, get a reference to it using the sender object and find the DataKeyValue of the master item using its NamingContainer, which is of type GridNestedViewItem.
Both of these methods are demonstrated in the attached web site sample. Please run the application and let me know if it helps you.
