In the BeforeOpenTables method of the DE, you can add code to access the Cursor objects of the DE, check the CursorSource property to see if it is the correct cursor, and change the property to something else.

When the DE does open the cursor, it will access the cursor object to get the necesasry information. Check out Message#349239 for an example.

HTH.
