RenderBeginTag() output not XHMTL compliant

[MatsL]

Hi,
This is seriously driving me crazy, could anyone explain to me why
neither of these doesn't produce XHTML compliant output (it is being
called in Render() btw):

output.WriteLine("<img src=\"" + vars["{$baseUrl}"] + " />");

output.AddAttribute(HtmlTextWriterAttribute.Src,
(string)vars["{$baseUrl}"]);
output.RenderBeginTag(HtmlTextWriterTag.Img);
output.RenderEndTag();

They both produce the same output:
<img src="/ChartImages/AllChart_68.jpg?KxRx=0x0974">

What I want is this:
<img src="/ChartImages/AllChart_68.jpg?KxRx=0x0974" />

Is there some setting that needs to be set or anything like that?


Thanks in advance!

Best regards,
Mats Lycken

the fragment is valid, but what is the parent element?

Is "output" an HtmlTextWriter or an XhtmlTextWriter? (what it is rendering
is proper HTML but not XHTML, similar to how <input> works)

Hello Mats,

As for the control/element rendering code, where did you call them? Are you
using these code to output some child html element in your custom webserver
control?

As for the XHTML content producing, ASP.NET 2.0 provide three Conformance
mode

**Legacy (which is similar to how markup was rendered in previous versions
of ASP.NET)

**Transitional (XHTML 1.0 Transitional)

**Strict (XHTML 1.0 Strict)

And the default one "Transitional" will help render most controls as XHTML
conformed output though it still includes a few exceptions. And if you set
the conformance mode to "Strict", it will force to page to output xhtml
content that conform to XHTML 1.0 Strict standard. You can get more
information about the ASP.NET 2.0 xhtml confromance setting in the
following MSDN reference:

#ASP.NET and XHTML
http://msdn2.microsoft.com/en-us/library/exc57y7e.aspx

for your problem here, I've just performed some test on my local side
through a custom webserver control, it seems that the output is correctly
XHTML conformed (set ASP.NET xhtml conformance as "Transitional" and use
IE6 to visit the page). Here is my test code:

==========================
protected override void RenderContents(HtmlTextWriter output)
{
output.AddAttribute("id", "divxhtml");
output.RenderBeginTag(HtmlTextWriterTag.Div);


output.WriteLine("<img
src=\"http://www.asp.net/i/www_asp_net_logo.gif\" />");

output.Write(Text );


output.AddAttribute(HtmlTextWriterAttribute.Src,
"http://www.asp.net/i/www_asp_net_logo.gif");
output.RenderBeginTag(HtmlTextWriterTag.Img);
output.RenderEndTag();


output.RenderEndTag();
}

==========================

and the web.config file just contains the following XHTML conformance
setting(the default value):

<xhtmlConformance mode="Transitional"/>


Please feel free to let me know if there is anything I missed or if you
have any other particular settings in your application.



Sincerely,

Steven Cheng
