Version 7.0 introduces the concept of control formulas.
The BaseApplicationTableControl, BaseApplicationRecordControl, FvLlsHyperLink, and LargeListSelector.Controls files in \App_Code\Shared needs are replaced during migration to add additional functions.
After migration, re-apply any customizations you may have made to the original BaseApplicationTableControl.cs (.vb) and BaseApplicationRecordControl.cs (.vb).
