title: How to Set Dataset in XtraReport
body: <p>i'm trying to create a simple XtraReport in my web-application. 
  for this, i create a DataSet Class in App_Code folder and drag Table from "Server Explorer" ToolBars in it. But this newly created DataSet Class doesn't show in XtraReport's DataSource dropdown list. Additionally, when i build the web site then lot of errors (almost 16 messages + 10 errors) occurs like these .. </p>
