Hi All
I got an error while working with Crystal reports
I have added a crystal report and set a command over there to get data.
I have added a crystalreportviewer named CRV to my web form and the code given as

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace Cryppp
	/// <summary>
	/// Summary description for WebForm1.
	/// </summary>
	public class WebForm1 : System.Web.UI.Page
		protected CrystalDecisions.Web.CrystalReportViewer CrystalReportViewer1;
		protected CrystalDecisions.Web.CrystalReportViewer CRV;
			Sample sr=new Sample();
		private void Page_Load(object sender, System.EventArgs e)
			// Put user code to initialize the page here
			sr.SetDatabaseLogon("sa", "", "as34", "pubs");

		#region Web Form Designer generated code
		override protected void OnInit(EventArgs e)
			// CODEGEN: This call is required by the ASP.NET Web Form Designer.
		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
			this.Load += new System.EventHandler(this.Page_Load);


the error was
