XhtmlTextWriter writes table and attributes problem

Hi all,
I am building a Composite control, and I need to render Xhtml content for my
control. Here is my sample code:

protected override void Render(HtmlTextWriter output) {
XhtmlTextWriter xWriter = new XhtmlTextWriter(output);

xWriter.AddAttribute(HtmlTextWriterAttribute.Cellpadding, "0");
xWriter.AddAttribute(HtmlTextWriterAttribute.Cellspacing, "0");
xWriter.RenderBeginTag(HtmlTextWriterTag.Table);
xWriter.RenderBeginTag(HtmlTextWriterTag.Tr);
xWriter.RenderBeginTag(HtmlTextWriterTag.Td);
xWriter.Write("Hello world");
xWriter.RenderEndTag();
xWriter.RenderEndTag();
xWriter.RenderEndTag();

xWriter.AddAttribute("src", "logo.gif");
xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.RenderEndTag();
}

And here is the output

RE: XhtmlTextWriter writes table and attributes problem

It seems that it is almost impossible to write "0" as attribute value im many
cases.

For example:

xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddAttribute(HtmlTextWriterAttribute.Border, "0");
xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.RenderEndTag();
Won't add border="0" to img tag.

xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddStyleAttribute(HtmlTextWriterStyle.BorderWidth, "0px");
xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.RenderEndTag();
Won't add border="0" to img tag.

xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddAttribute("borderwidth", "0");
xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.RenderEndTag();
Won't add border="0" to img tag.

xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddStyleAttribute(HtmlTextWriterStyle.BorderWidth, "0");
xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.RenderEndTag();
Won't add border="0" to img tag.

Is it a bug from MS?

Hi,

Can you try the following code please.

xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddAttribute(HtmlTextWriterAttribute.Border, "0");
xWriter.RenderEndTag();

xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddStyleAttribute(HtmlTextWriterStyle.BorderWidth, "0px");
xWriter.RenderEndTag();

xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddAttribute("borderwidth", "0");
xWriter.RenderEndTag();

xWriter.RenderBeginTag(HtmlTextWriterTag.Img);
xWriter.AddAttribute(HtmlTextWriterAttribute.Src, "a.gif");
xWriter.AddStyleAttribute(HtmlTextWriterStyle.BorderWidth, "0");
xWriter.RenderEndTag();
