How to set the background color of a web page using code behind?

Yes

1. In the body tag, add runat=’server’ and give the tag an id (e.g. id=’bodyID’).
2. In the class definition in the code-behind, add
   VB.NET

   
   Protected bodyID As System.Web.UI.HtmlControls.HtmlGenericControl
   

   C#

   
   protected  System.Web.UI.HtmlControls.HtmlGenericControl bodyID  ;
   

3. In code, use the attributes collection to set the bgcolor attribute:
   VB.NET

   
   bodyID.Attributes.Add('bgcolor', 'green')
   

   C#

   
   bodyID.Attributes.Add('bgcolor', 'green');
