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.

The following code sniplet will do the trick.

Example:

First:
I created an assembly called WebPageBase and a class in the assembly called PageBase. My class inherits from
System.Web.UI.Page like a normal aspx page does.
namespace WebPageBase
{
///


/// Main Base for RealtorNavigator Web
///

///[Designer(typeof(System.Web.UI.Page))]
public class PageBase : System.Web.UI.Page
{
}

Next: Add this method in the PageBase class:
///
/// 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. Hope M$ doesn't decide to change the case of these tags anytime soon.
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;

// Strip out the viewstate.
string viewstate = html.Substring( start, end - start );
html = html.Remove( start, end - start );

// Find the end of the form and insert it there, since we can't put it any lower in the response stream.
int formend = html.IndexOf("") - 1;
html = html.Insert( formend, viewstate );
}

// Send the results back into the writer provided.
writer.Write( html );
}

Finally:
Inherit your aspx pages from the base class.
Example:
public class Default : WebPageBase.PageBase
{
// Your code here
}
Note: I put my PageBase instead of the VisualStudio System.Web.UI.Page
