Another way to moving ViewState to the bottom of 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 the 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();
        
        // Close 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
}
