Kommentarer

Metoden RenderEndTag ger ytterligare formatering efter att basklassens metod anropats HtmlContainerControl.RenderEndTag . Med den extra formateringen blir kontrollens HtmlTable renderade HTML lättare att läsa genom att infoga en radretur efter den avslutande <table> taggen.

Metoden RenderChildren används främst av kontrollutvecklare som utökar kontrollens HtmlTable funktioner.
