Thanks...I'll work through it using your excellant answer!!

>Approach Two - Trick the Grid using MM.NET Business Object AND defining a Typed Dataset that is then referenced in your form code so the Grid can import the schema information
>1. Review the MM.NET Dev Guide for how to configure your Business Objects to create typed datasets rather than their default behavior and change your BO as required.
>2. In the form code, create a reference to this typed dataset

>3. Add a dataset to the form by dragging from the toolbox data tab
>4. In the dialog Add Dataset - select typed dataset and in the name combobox select Referenced datasets and then select the dataset name from the listing

>9. Complete the desired other grid properties
>10. Make sure the Grid's Binding Source is set in code or in the properties to the MM.NET business object in which you just selected for the schema
>11. Change both hidden and header.caption properties as desired in the UltraWinGridDesigner Band and Column Settings - Band 0 (or appropriate Band #) - Columns ColumnName - Hidden property (False to True) and Header.Caption property to read as the column heading needs to be displayed.
