TextBlockFormatting not work properly in Datasource binding

[Shanti 😎]

I am binding a Datasource to RadCheckedDropDownList. This RadCheckedDropDownList have checked items. TextBlockFormatting not working binding time (Figure 1).
After binding i checked or unchecked item TextBlockFormatting working properly(Figure 2). I need a RadCheckedDropDownList like Figure 2..
Waiting for your favourable response.


Binding code...
RadCheckedDropDownList1.DataSource = Nothing
RadCheckedDropDownList1.CheckedMember = "vaIsProductVariant"
RadCheckedDropDownList1.DisplayMember = "ProductVariantValueID"
RadCheckedDropDownList1.ValueMember = "VariantValue"
RadCheckedDropDownList1.DataSource = value


Formatting Code....
Private Sub chkVariantValue_TextBlockFormatting(sender As Object, e As TextBlockFormattingEventArgs) 

        Dim token As TokenizedTextBlockElement = TryCast(e.TextBlock, TokenizedTextBlockElement)

        If token IsNot Nothing Then
            token.GradientStyle = Telerik.WinControls.GradientStyles.Solid
            token.BackColor = ColorTranslator.FromHtml(TokenColor)
            token.BorderColor = ColorTranslator.FromHtml(TokenColor)
            token.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
            token.Shape = New RoundRectShape
        End If

End Sub

Hello, Shanti, 

Your question has already been answered in the other thread you have posted on the same topic. Please, see our answer there for more information.
We kindly ask you to use just one thread for a specific problem to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two or more tickets instead of one. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.

Note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread. 

Thank you for your understanding.
