Why does Gridview ALWAYS emit style="border-collapse: collapse;"

[Tom Castiglia]

I am inheriting from the GridView and I noticed the GridView ALWAYS emits its
table tag with a style attribute containing "border-collapse: collapse". I
have tried everything that I can think of to remove this style, but without
results.

I have tried the following:

Attributes.CssStyle.Remove(HtmlTextWriterStyle.BorderCollapse);
Attributes.CssStyle.Clear()

I have attempted this from the RenderContents(), OnInit(), and OnPreRender()
methods. The problem is that even in the RenderContents() method, the
Attributes.CssStyle.Count properties is 0. So it seems that the
Border-Collapse style is not added until a later point in the control's
lifecycle.

Any thoughts on this? It seems to be really improper for the Gridview to
inject this style into HTML. I really need to control the control's style
through a CssClass.

Hi Tom,

It's incorrectly hardcoded in ASP.NET in some places.

Try this?

GridView1.GridLines = GridLines.None
GridView1.CellSpacing=-1

Note that you'll still get

border="0"

Nothing can be done about that til there's an update.

Let us know if this helps?

Ken,

Thank you...That worked!

Can you also figure out how to get me back the 10 hours I spent working on
this problem?
