Remove span tag from webcontrol
===

> I have seen a few examples of how to do this such as:


    Imports System.Globalization
    Imports System.Web.UI
    Imports System.Web.UI.WebControls
    
    Protected Overrides Sub Render(writer As HtmlTextWriter)
        RenderContents(writer)
    End Sub

> RenderContents is not declared. What am I missing?
