Which of the following properties binds the object to a source from which data is to be retrieved?
The RecordSource property belongs to the form and report objects. This property binds the object to a source from which data is to be retrieved. This source can be a table or a query. When a form or a report is bound to a table or a query, the controls can be bound to a column of the table through the ControlSource property.
Answer option D is incorrect. The ControlSource property bounds a control to a field of a table. If a control is bound to a field by using this property, the control is known as a bound control. If the value of this property is blank, the control is known as an unbound control. If the ControlSource property contains an expression, the control is known as a calculated control.
Answer option C is incorrect. The RowSource property belongs to the combo box and list box controls. When these controls are bound to a column by the RowSource property, all the data of the column is displayed in the list box or the combo box.
Answer option B is incorrect. The TextFormat property of a control helps to change a text to rich text format. This helps to apply multiple formatting options for the text in a control.
