Hello,

We have a DNN website with community version. We are getting a very big View State in DNN page, and this is not good for SEO(Search Engine Optimization).

So to remove viewstate at the bottom of page I added render method in Default.aspx.vb in my DNN website as following :

Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
      Dim stringWriter As New System.IO.StringWriter()
      Dim htmlWriter As New HtmlTextWriter(stringWriter)
      MyBase.Render(htmlWriter)
      Dim html As String = stringWriter.ToString()
      Dim StartPoint As Integer = html.IndexOf("<input type=""hidden"" name=""__VIEWSTATE""")
      If StartPoint >= 0 Then
        Dim EndPoint As Integer = html.IndexOf("/>", StartPoint) + 2
        Dim viewstateInput As String = html.Substring(StartPoint, EndPoint - StartPoint)
        html = html.Remove(StartPoint, EndPoint - StartPoint)
        Dim FormEndStart As Integer = html.IndexOf("</form>") - 1
        If FormEndStart >= 0 Then
          html = html.Insert(FormEndStart, viewstateInput)
        End If
      End If
      writer.Write(html)
      ''MyBase.Render(writer)
    End Sub

With this change I am getting the view state at the bottom of the page. But now in Admin/host mode  "Control Panel" of DNN is not working.

 And I am not getting options of adding page, adding modules to a page, etc..

Can anyone please help on this.

Thanks and Regards,

Ashish Shukla

Hi Cathal,

Thaks for your quick reply.

Can you please suggest that how we can configure spider robot content to handle viewstate issue?

We want crawler to crawl on a page for reading page content.

Thanks in advance,
