Locked Property
The Locked property specifies whether you can edit data in a control in Form view. Read/write Boolean.expression.Locked
expression Required. An expression that returns one of the objects in the Applies To list.
Remarks
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.
Example
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
Else
Me!SalaryDetails.Enabled = False
Me!PersonalInfo.Enabled = False
Me!PersonalInfo.Locked = True
End If
End Sub
