You can add columns that are included in the data source to a DataWindow object. When you first create a DataWindow object, each of the columns in the data source is automatically placed in the DataWindow object. Typically, you would add a column to restore one that you had deleted from the DataWindow object, or to display the column more than once in the DataWindow object.
Adding columns not previously retrieved to the data source To specify that you want to retrieve a column not previously retrieved (that is, add a column to the data source), you must modify the data source.
To add a column from the data source to a DataWindow object:
Select Insert>Control>Column from the menu bar.
Click where you want to place the column.
The Select Column dialog box displays, listing all columns included in the data source of the DataWindow object.
Select the column and click OK.
