Disable User control

James Tyler

9/28/2011 10:10:00 PM

How do I disable an user control. It looks like I have to call a function in
the user control to do that. Why ? I can set the .Visible but I don't even
see the .Enabled property

TIA

Using the ActiveX Control Wizard you can add the Enabled Property.

I see an Enabled property for a userControl. But in
general I use an Enabled property that I create myself,
because I want to control the item(s) on the control.

The control is basically a form. If I have an RTB on the UC
I create an Enabled property that uses EnableWindow to
activate or deactivate the RTB. Likewise, if I build a button
UC I might have an Enabled property determines the color
of the button and whether it responds to clicks.

You have to write it yourself. The simplest form of doing this would just be
this:

Public Property Let Enabled(ByVal NewValue As Boolean)

UserControl.Enabled = NewValue

End Property

Public Property Get Enabled() As Boolean

Enabled = UserControl.Enabled

End Property


However, that will not cause any constituent controls to appear disabled.
It's just like putting controls in a PictureBox and disabling the
PictureBox. The controls are disabled because their container is disabled,
but they don't have a disabled appearance.

I see. Sorry. I didn't notice that. I still wonder
why you need it, though. I use several UCs and
all of them have custom Enabled properties that
relate to the controls/windows on the UC. The UC
is a container, like a Form. A Form, also, doesn't
have a runtime Enabled property.

Start a new project, add a user control, then add a command button and the
control to the form. Put this in the form:

Private Sub cmdCommand1_Click()
UserControl11.Enabled = Not UserControl11.Enabled
End Sub

Put this in the user control and try changing the Enabled property for the
control in the IDE and after running the project.

Private mbEnabled As Boolean

Private Sub UserControl_InitProperties()
mbEnabled = True
End Sub

Private Sub UserControl_ReadProperties(PropBag As PropertyBag)
mbEnabled = PropBag.ReadProperty("Enabled", True)
ShowEnabledState
End Sub

Private Sub UserControl_WriteProperties(PropBag As PropertyBag)
PropBag.WriteProperty "Enabled", mbEnabled
End Sub

Public Property Get Enabled() As Boolean
Enabled = mbEnabled
End Property

Public Property Let Enabled(ByVal NewState As Boolean)
mbEnabled = NewState
ShowEnabledState
End Property

Private Sub ShowEnabledState()
UserControl.BackColor = IIf(mbEnabled, vbWhite, vbBlack)
End Sub
