Override CssClass property

Question

User-1821120043 posted

I am creating a "disabled" linkbutton control where the developer can specify a "DisabledCssClass".  I am trying to override the CssClass property to return the "DisabledCssClass" string instead of the CssClass (when applicable).  Problem seems to be that the Get never gets called to execute the code...even when i explicitly call it.  Any ideas?  Here is my code

 

Public Overrides Property CssClass() As String
            Get
                If Me.Enabled Then
                    Return MyBase.CssClass
                Else
                    If Not Me.DisabledCssClass = String.Empty Then
                        Return Me.DisabledCssClass
                    Else
                        Return MyBase.CssClass
                    End If
                End If
                Return MyBase.CssClass
            End Get
            Set(ByVal value As String)
                MyBase.CssClass = value
            End Set
        End Property

Hmmm....I think you defined the propert perfectly but the cssclass property that is getting called is from the base class and not your custom control class. I faced this situation whne i was overriding the text property. Use the shadows keyword to hide the base class property and to ensure that your property gets called.

the example is listed below

the text marked in bold is important
Public Shadows Property Text() As String
Get
Return GetText()
End Get
Set(ByVal value As String)
SetText(value) 'calling some utility function to set the text
End Set
End Property

Excellent.  I don't use Shadows very much, so completely forgot about it.

Well, that didn't work either.  I changed Overrides to Shadows and still the Get isn't being called.  The Set is still getting called.  Is this something to do with how the control renders?  Is it possible that when it goes to add the cssclass, it is calling some other method? The funny thing is that I am overriding the text property in the same control and it works great.

hmmm...sounds surprising
If its going in the set it should also o in the get.

Can u confirm if the enabled property is coming false and code does not go in the "if me.enabled" section
