Patty,

>The biz object is now registered once. The new row is displayed in the form, but when the Save button is pressed, the data that has been entered never makes it to the dataset for saving. If I walk thru the HookPreSave code, the datarow contains the original default values that were set when the row was added. This implies a breakdown with binding, right?

When you say the new row is displayed in the form, is it displayed in a DataGrid or in a set of user interface controls such as text boxes, etc? If the new row is displayed in the form, that means it has been data bound. There is automatic two-way data binding in Windows Forms so the values entered in the UI should automatically be bound back to the DataRow...
