DisplayControl Property
You can use the DisplayControl property in table Design view to specify the default control you want to use for displaying a field.
Setting
You can set the DisplayControl property in the table's property sheet in table Design view by clicking the Lookup tab in the Field Properties section.
This property contains a drop-down list of the available controls for the selected field. For fields with a Text or Number data type, this property can be set to Text Box, List Box, or Combo Box. For fields with a Yes/No data type, this property can be set to Check Box, Text Box, or Combo Box.
Remarks
When you select a control for this property, any additional properties needed to configure the control are also displayed on the Lookup tab.
Tip You can let Microsoft Access set the DisplayControl property and any related properties for you when you select the Lookup Wizard as the data type for a field.
Setting this property and any related control type properties will affect the field display in both Datasheet view and Form view. The field is displayed by using the control and control property settings set in table Design view. If a field had its DisplayControl property set in table Design view and you drag it from the field list in form Design view, Microsoft Access copies the appropriate properties to the control's property sheet.
