Enabled Property
Specifies whether a control can receive the focus and respond to user-generated events.
Syntax
object.Enabled [= Boolean]
The Enabled property syntax has these parts:
| Part | Description |
|---|---|
| object | Required. A valid object. |
| Boolean | Optional. Whether the object can respond to user-generated events. |
Settings
The settings for Boolean are:
| Value | Description |
|---|---|
| True | The control can receive the focus and respond to user-generated events, and is accessible through code (default). |
| False | The user cannot interact with the control by using the mouse, keystrokes, accelerators, or hotkeys. The control is generally still accessible through code. |
Remarks
Use the Enabled property to enable and disable controls. A disabled control appears dimmed, while an enabled control does not. Also, if a control displays a bitmap, the bitmap is dimmed whenever the control is dimmed. If Enabled is False for an Image, the control does not initiate events but does not appear dimmed.
The Enabled and Locked properties work together to achieve the following effects:
- If Enabled and Locked are both True, the control can receive focus and appears normally (not dimmed) in the form. The user can copy, but not edit, data in the control.
- If Enabled is True and Locked is False, the control can receive focus and appears normally in the form. The user can copy and edit data in the control.
- If Enabled is False and Locked is True, the control cannot receive focus and is dimmed in the form. The user can neither copy nor edit data in the control.
- If Enabled and Locked are both False, the control cannot receive focus and is dimmed in the form. The user can neither copy nor edit data in the control.
You can combine the settings of the Enabled and the TabStop properties to prevent the user from selecting a command button with TAB, while still allowing the user to click the button. Setting TabStop to False means that the command button won't appear in the tab order. However, if Enabled is True, then the user can still click the command button, as long as TakeFocusOnClick is set to True.
When the user tabs into an enabled MultiPage or TabStrip, the first page or tab in the control receives the focus. If the first page or tab of a MultiPage or TabStrip is disabled, the first enabled page or tab of that control receives the focus. If all pages or tabs of a MultiPage or TabStrip are disabled, the control is disabled and cannot receive the focus.
If a Frame is disabled, all controls it contains are disabled.
Clicking a disabled ListBox does not initiate the Click event.
