I do I remove the style attribute from Image controls?

[J055]

Hi

A number of controls which use images seem to render html with a default
style attribute: style="border-width:0px;"

e.g.

<input type="image" name="ctl00$Main$ImageButton1"
id="ctl00_Main_ImageButton1" src="images/address_book.gif"
style="border-width:0px;" />

<img id="ctl00_Main_Image1" src="images/delete.gif"
style="border-width:0px;" />


I'd like to remove it from all of these controls because it's a waste of
mark-up and we use external stylesheets to style web pages.

I've tried things like this in the Load and PreRender page events but the
style refuses to disappear.

ImageButton1.Style.Clear();
ImageButton1.Style.Remove.("border-width");

Any suggestions?

Thanks
Andrew

Not an answer, but just to let you know that we ran into a similar problem
with the GridView and haven't yet found a way to remove it.

That attribute seems to be hardwired in.

Hi

Thanks for the response. Looks like you're right about hardwiring. Using the
Reflector tool to disassemble the Image control I found it contained an
AddAttributesToRender method with this code tucked in at the bottom:


if (this.BorderWidth.IsEmpty)
{
if (base.EnableLegacyRendering)
{
writer.AddAttribute(HtmlTextWriterAttribute.Border, "0",
false);
}
else
{
writer.AddStyleAttribute(HtmlTextWriterStyle.BorderWidth,
"0px");
}
}


I'm sorry Microsoft but that is just plain wrong!

Hi Andrew,

Yes, it is a bit dummy that the style is hard coded. Currently what I can
get is using the html image server control instead or creating a custom
control to render the clear image element.
