[RESOLVED] TypeConverter?

[VBDT]

Hi everyone, I have a UserControl that I want to show some of its properties whit the percentage char like (100%) so I created a class that inherits from TypeConverter class. For some reason it doesn’t work see the image. What could be the problem?
Thanks in advance!

Here is the class:

Public Class PercentageConverter
        Inherits TypeConverter
 
        Public Sub New()
 
        End Sub
 
        Public Overloads Overrides Function CanConvertFrom(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal sourceType As System.Type) As Boolean
            If sourceType Is GetType(String) Then
                Return True
            End If
            Return MyBase.CanConvertFrom(context, sourceType)
        End Function
 
        Public Overloads Overrides Function ConvertFrom(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal culture As System.Globalization.CultureInfo, ByVal value As Object) As Object
            If TypeOf value Is String Then
                Dim s As String
                s = CStr(value)
                If s.EndsWith("%") Then
                    s = (CStr(value)).Substring(0, (CStr(value)).Length - 1)
                End If
                Return Double.Parse(s, NumberStyles.Any, culture) / 100
            End If
            Return MyBase.ConvertFrom(context, culture, value)
        End Function
 
        Public Overloads Overrides Function ConvertTo(ByVal context As System.ComponentModel.ITypeDescriptorContext, ByVal culture As System.Globalization.CultureInfo, ByVal value As Object, ByVal destinationType As System.Type) As Object
            If destinationType Is GetType(String) Then
                Dim v As Double
                v = CDbl(value) * 100
                Return CStr(v) & "%"
            End If
            Return MyBase.ConvertTo(context, culture, value, destinationType)
        End Function
 
    End Class

and this is how i use it:

''' <summary>
    ''' Gets or sets the size of the center-point that is directly proportional to the circumference of the clock.
    ''' </summary>
    <DefaultValue(0.03R), TypeConverterAttribute(GetType(PercentageConverter)), _
    Bindable(True), Category("Layout"), Description( _
    "Indicates the size of the center-point that is directly proportional to the circumference of the clock.")> _
      Public Property CenterPointSize() As Double
        '<DebuggerHidden()> _
        Get
            Return Me._centerPointRatio
        End Get
        '<DebuggerHidden()> _
        Set(ByVal value As Double)
            If Not Me._centerPointRatio.Equals(value) Then
                If value < 0 Or value > 1 Then
                    Throw New Exception("The value should be in the range of 0 to 100.")
                Else
                    Me._centerPointRatio = value
                    Me.SetCenterPointPath()
                    Me.ClockPanel.Invalidate()
                    Me.ClockPanel.Update()
                End If
            End If
        End Set
    End Property
