Can anyone tell me where I could find the namespaces available for ASP.NET and a definition of what they do? Just in case I am calling it something different than it is, I am referring to the code placed at the top of an ASP.NET page that looks like this:<BR><BR><%@ Import Namespace="System.Data" %><BR><BR>Also, do you need to have something like this at the top of every page or is there a default namespace loaded for basic processing.<BR><BR>ThanksI like to use the class documents at (http://msdn.microsoft.com/library/en-us/cpref/html/cpref_start.asp).<BR><BR>The default namespaces that are loaded vary depending on the type of page/project. For example, a ASP.NET page automatically has access to the System.Web.UI.WebControls (among others) class. You don't need to have an import or using directive in a .aspx page to use the WebControls. If you were using a code behind file then you still need to specify all namespaces being used.<BR><BR>hth,<BR>Alex<BR><BR>ASP.NET Examples/Tips: http://aspalliance.com/aldotnet
