Question

In my master pages I have <form ... action='' ...>, in pre SP1, if I viewed the source the action attribute would be an empty string. In SP1 the action attribute is overridden ‘MyPage.aspx?MyParams’, unfortunately, this causes my postbacks to fail as I have additional pathinfo in the URL (ie. MyPage.aspx\CustomerData?MyParams). I have checked the action attribute in the OnLoad event and it is still blank at this time, so somewhere SP1 is overriding this :(.

Sorry, I just realized that part of my post was missing since I did not use the markdown correctly.

Great solution from MrJavaGuy but there is a typo in the code because pasting code in the box here doesn’t always work correctly. There is a duplication on the WriteAttribute method, corrected code is as follows –

public class HtmlFormAdapter : ControlAdapter  {     protected override void Render(HtmlTextWriter writer)     {         HtmlForm form = this.Control as HtmlForm;          if (form == null)         {             throw new InvalidOperationException('Can only use HtmlFormAdapter as an adapter for an HtmlForm control');         }         base.Render(new CustomActionTextWriter(writer));     }       public class CustomActionTextWriter : HtmlTextWriter     {         public CustomActionTextWriter(HtmlTextWriter writer) : base(writer)         {             this.InnerWriter = writer.InnerWriter;         }          public override void WriteAttribute(string name, string value, bool fEncode)         {             if (name == 'action')             {                 value = '';             }             base.WriteAttribute(name, value, fEncode);               }     } }
