Border Attribute on Table Webcontrol

U

Unknown

When I create a Table webcontrol programmatically (no static table tag in
the aspx file), it renders in the HTML with a border attribute set to "0".

If I add my own border attribute--MyTable.Attributes.Add("border",
"1")--with a value of "1", the border attribute shows up twice in the HTML
tag in the browser.

How can I suppress the default border attribute of "0" for the Table
webcontrol?

Thanks
Phil

Pretty basic stuff here. Below you will find the code for the aspx file,
the c# code behind file, and the html markup taken from "view source" in the
browser window. Please note that the border attribute is repeated twice in
HTML file for the table.

The operating environment is:
-- VS.Net: 7.0
-- .Net Framework: 1.0
-- IE: 6.0

Thanks,
Phil

Have you tried, instead of
tbl.Attributes["border"] = "1";
Click to expand...

simply

tbl.Border = 1;

Using "tbl.Border = 1" seems to create an inline CSS style; We want to use
only the border attribute of the table element in this particular case for a
number of unrelated reasons.
