ControlAdapter sample from Scott Gu no more work ?

Hello,

Using url rewritting and ajax.net, I tried to circumvent some potential
problems with postback url using a code from a sample given by Scott.
The idea is to use a control Adapter on htmlform to catch the attribute
'action' wich contains the url where the post will occur and replace it with
a safe url.
Unfortunately, it doesn't works, does something has changed with framework
3.5 used by vs2008 ?
From the trace I put inside I can see that the adapter is working but I
never get an attribute named action ????

Here is the code:

public class FormRewriterControlAdapter : ControlAdapter
{
protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
base.Render(new RewriteFormHtmlTextWriter(writer));
}
}

public class RewriteFormHtmlTextWriter : HtmlTextWriter
{
public RewriteFormHtmlTextWriter(HtmlTextWriter writer)
: base(writer)
{
InnerWriter = writer.InnerWriter;
}

public RewriteFormHtmlTextWriter(TextWriter writer)
: base(writer)
{
InnerWriter = writer;
}

/// <summary>
/// If the attribute we are writing is the "action" attribute, and
we are not on a sub-control,
/// then replace the value to write with the raw URL of the
request - which ensures that we'll
/// preserve the PathInfo value on postback scenarios
/// </summary>
public override void AddAttribute(string name, string value, bool
fEncode)
{
HttpContext Context =
HttpContext.Current;
if ( name.Equals("action") )
{
if (Context != null && Context.Items["ActionAlreadyWritten"]
== null)
{
value =
Context.Request.RawUrl;
// Indicate that we've already rewritten the <form>'s
action attribute to prevent
// us from rewriting a sub-control under the <form>
control
Context.Items["ActionAlreadyWritten"] = true;
}
}
base.AddAttribute(name, value, fEncode);
}

}

I have also a special declaration in my web site Form_Browsers folder

<browsers>
<browser refID="Default">
<controlAdapters>
<adapter controlType="System.Web.UI.HtmlControls.HtmlForm"
adapterType="AddonNice.Core.UI.Adapters.FormRewriterControlAdapter" />
</controlAdapters>
</browser>
</browsers>



Thanks to any help on this, it is so simple that the error must be
evident.....but.

HtmlForm as been recoded and no longer uses the attribute collection to
determine what to render for the action. Action has been exposed as a
property you can just set in your code or your adapter.

Hi,

I've tested Scott's project:
http://www.scottgu.com/blogposts/urlrewrite/UrlRewrite_HttpModule1.zip

It works fine. Could you try it again to see if it works? Firstly please
view the page Default.aspx. Then click a link on the page to view
Products.aspx. View source of Products.aspx and you will see the action
attribute in the form tag:
<form name="form1" method="post" action="/SOS/Products.aspx" id="form1">

Hi,

I believe the change what Bruce mentioned is in the .NET 3.5 SP1. Are you
using .NET 3.5 SP1?

Actually the Action property is a shortcut to set/get the action attribute.
We can confirm it with the source code below:

public string Action
{
get
{
string str = base.Attributes["action"];
if (str == null)
{
return string.Empty;
}
return str;
}
set
{
base.Attributes["action"] =
HtmlControl.MapStringAttributeToString(value);
}
}


I tried Scott's project in Visual Studio 2008 SP1, it still works. Could
you try it again and paste the form tag here? The behavior on my side is:

1. Default.aspx:
<form name="form1" method="post"
action="/UrlRewrite_HttpModule1/Default.aspx" id="form1">

2. I clicked "Books" link to view Products.aspx:
<form name="form1" method="post"
action="/UrlRewrite_HttpModule1/Products/Books.aspx" id="form1">

Yes I am using the 3.5 SP1.
I try your code and give a feed-back, thanks.
