Move ViewState to the bottom of the page

If you move your viewstate from the top of the page to the bottom, you will get better search engine spidering.

 

Step 1 :

Create a class file in App_code folder of your application and name it as "PageBase.cs". Copy following code to the class file.

 

using System.IO;

using System.Web.UI;

 

namespace WebPageBase

{

public class PageBase : System.Web.UI.Page

{

/// This method overrides the Render() method for the page and moves the ViewState

/// from its default location at the top of the page to the bottom of the page. This

/// results in better search engine spidering.

 

protected override void Render(System.Web.UI.HtmlTextWriter writer)

{

// Obtain the HTML rendered by the instance.

StringWriter sw = new StringWriter();

HtmlTextWriter hw = new HtmlTextWriter(sw);

base.Render(hw);

string html = sw.ToString();

 

// Hose the writers we don't need anymore.

hw.Close();

sw.Close();

 

// Find the viewstate.

int start = html.IndexOf(@"<input type=""hidden"" name=""__VIEWSTATE""" );

// If we find it, then move it.

if (start > -1)

{

int end = html.IndexOf("/>", start) + 2;

 

string strviewstate = html.Substring(start, end - start);

html = html.Remove(start, end - start);

 

// Find the end of the form and insert it there.

int formend = html.IndexOf(@"</form>") - 1;

html = html.Insert(formend, strviewstate);

}

 

// Send the results back into the writer provided.

writer.Write(html);

}

}

}

 

 

Step 2 :

Inherit your aspx pages from the base class.

 

public partial class Page : WebPageBase.PageBase

{

// Your code here

}
