Public Shared Function ControlToHTML(ByVal Control As System.Web.UI.Control) As String
06
Dim sHTML As String = String.Empty
07 Dim oTextWriter As New System.IO.StringWriter()
08 Dim oHTMLWriter As New System.Web.UI.HtmlTextWriter(oTextWriter)

環境設定:
1.Page 要覆寫 VerifyRenderingInServerForm 方法
1 Public Overrides Sub VerifyRenderingInServerForm(ByVal Control As System.Web.UI.Control)
2 '覆寫，不執行 MyBase.VerifyRenderingInServerForm 方法，解決執行 RenderControl 產生的錯誤
3End Sub
Public Overrides Sub VerifyRenderingInServerForm(ByVal Control As System.Web.UI.Control)2
'覆寫，不執行 MyBase.VerifyRenderingInServerForm 方法，解決執行 RenderControl 產生的錯誤3
End Sub
2.在 <%@ Page %> 中加入 EnableEventValidation="false"
<%@ Page Language="VB" AutoEventWireup="false" EnableEventValidation="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
