I have the following c# code in my control's RenderContents method. How can I add the style/class that is in external css file?
output.AddAttribute(HtmlTextWriterAttribute.Border, "0");
output.AddAttribute(HtmlTextWriterAttribute.Width, "100%");
output.RenderBeginTag(HtmlTextWriterTag.Table);
output.RenderBeginTag(HtmlTextWriterTag.Tbody);
output.RenderBeginTag(HtmlTextWriterTag.Tr);
//Here -> Need to add some style from external stylesheet.css file
output.RenderBeginTag(HtmlTextWriterTag.Td);
rblLoadSelection.RenderControl(output);
output.RenderEndTag(); //Td
output.RenderEndTag(); //Tr
output.RenderEndTag(); //Tbody
output.RenderEndTag(); //Table
