Locked Property [Access 2003 VBA Language Reference]

The Locked property specifies whether you can edit data in a control in Form view. Read/write Boolean.


expression Required. An expression that returns one of the objects in the Applies To list.


The Locked property uses the following settings.

Setting Visual Basic Description
Yes True (Default for unbound object frames) The control functions normally but doesn't allow editing, adding, or deleting data.
No False (Default for all controls except unbound object frames) The control functions normally and allows editing, adding, and deleting data.

You can set these properties by using a form's property sheet , a macro , or Visual Basic .

Use the Locked property to protect data in a field by making it read-only. For example, you might want a control to only display information without allowing editing, or you might want to lock a control until a specific condition is met.


The following example toggles the Enabled property of a command button and the Enabled and Locked properties of a control, depending on the type of employee displayed in the current record. If the employee is a manager, then the SalaryDetails button is enabled and the PersonalInfo control is unlocked and enabled.

Sub Form_Current()
    If Me!EmployeeType = "Manager" Then
        Me!SalaryDetails.Enabled = True
        Me!PersonalInfo.Enabled = True
        Me!PersonalInfo.Locked = False
        Me!SalaryDetails.Enabled = False
        Me!PersonalInfo.Enabled = False
        Me!PersonalInfo.Locked = True
    End If
End Sub
