BoundColumn Property
This property returns or sets the name of the source field in a Recordset (Data control) object that is used to supply a data value to another Recordset (Data control).
object.BoundColumn= value
Read/Write at run time and design time.
Property applies to TDBList and TDBCombo controls.
Generally, you will use the TDBList and TDBCombo controls with two Data controls: one to fill the list as designated by the RowSource property, and one to update a field in a database as designated by the DataSource and DataField properties.
When the user selects an item from a TDBList control or the list portion of a TDBCombo control, the BoundColumn property determines which RowSource field supplies the data value to be used for the update. You can use the following pseudo-code to help you remember how to configure a list or combo control at design time:
DataSource.DataField = RowSource.BoundColumn
The left side of the assignment statement specifies the field to be updated; the right side specifies the set of allowable values.
Note: Do not confuse the BoundColumn property with the ListField property used to specify the incremental search field.
