Expandable properties update from TypeConverter

Hi,

I am sorry if this is a stupid question, but I am new to expandable properties.

When I change the value of TextAlpha I would like the clsButton to get informed and update the m_AlphaText variable.
How do I do that?

In advance thank you,
Henrik

Public Class clsButton
    Inherits Button

    Private m_Text As New TextProperties
    Private m_AlphaText As Integer = 100

    <CategoryAttribute("Design"), _
RefreshProperties(RefreshProperties.All), _
DisplayName("Text Properties"), _
Description("All text properties")> _
    Public Property TextProp() As TextProperties
        Get
            Return m_Text
        End Get
        Set(ByVal value As TextProperties)
            m_Text = value
        End Set
    End Property
End Class


    <TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class TextProperties
    Private m_AlphaText As Integer = 100
 
    <DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _
    Browsable(True), NotifyParentProperty(True),
    EditorBrowsable(EditorBrowsableState.Always)>
    Public Property TextAlpha() As Integer
        Get
            Return m_AlphaText
        End Get
        Set(ByVal value As Integer)
            If value < 256 And value > -1 Then
                m_AlphaText = value
            Else
                MsgBox("Min. alpha is 0 and max. alpha is 255")
                m_AlphaText = 100
            End If
        End Set
    End Property
End Class
