ComboBox

Adding Items: add elements to the Items property. „Value” is the key property which uniquely identifies the items of the ComboBox. This property may be an integer field from the DataSet.

Before creating your own ComboBox, take into consideration that one may be already available. ComboBoxes can be filled with already existing values

When using controls whose value are retrieval arguments bind the control to the argument of the DataSet, not the field from the table.
