Why can't I use System.Data namespace in a web custom control? I am making a reference to the namespace
System.Data in the following snippet

[ToolboxData("<{0}:WebTrailLogger runat=server creator=raza></{0}:WebTrailLogger>")]
public class PWWebTrailLogger
{
// override the DayRender function
public void Log(WEB_AUDIT_TRAIL_INFO info,string userId,string SessionId)
{
try
      {
      DAWebRequestTrail objDA = new DAWebRequestTrail(
            Connection.getConnectionString((int)Constant.CONNECTIONSTRINGLOCATIONS.SETTINGS_XML,
                              (int)Constant.DATABASE.DATABASE1)
                              );
      // Get an Empty Dataset
      DataSet ds = objDA.Get("");
      objDA.Get(userId);
      }
catch(Exception err)
{
      Debug.WriteLine(err.ToString());
}
}
}

But the compiler would not let it go until it sees

using System.Data on the top?

What do I need to do?

Instead of the "using..." clause, you might as well use the fully qualified name.. System.Data.DataSet .. etc.

Yes, of course we can use fully qualified name
like System.Data.DataSet but the problem is in the context of Web Custom Control that namespace is not visible. Does anyone know why?

Hmm. I haven't heard of any restrictions regarding use of specific namespaces in composite server controls.

In this article about creating composite server control .. the author uses System.Data.

Got it figured out. The namespace does not get included automatically in the references node. It has to manually added.
