The best solution is using stored procedure...............
1.Make A Store Procedure with all the fields from the table which is required in the report.
2.then add a .rpt file in your solution.
3.for designing of report, in field explorer add the stored procedure you made.Drag and drop the fields in the way you want.

You can directly add tables in the field explorer in place of making stored procedure.......but the report will open very slow as the data in database will increase..........................

using visual studio u can do crystal report
If u cant instead u can use gridview

We can create a crystal report.net using the following steps:

Create a Dataset and define the schema by drag and drop the database table from Server Explorer.
If there are multiple tables then put all the tables within one dataset itself.

STEPS:
Right Click Solution Explorer -> Add -> Add New Item -> choose DataSet under the Categories (Web Project Items - data).

Add new Connection in the Server Explorer and expand the connection to retrieve the database tables and choose the required table and drag and drop it in the Dataset xsd pane.

Generate Dataset from the Dataset XSD.

STEPS:
Right click on the dataset xsd pane and click Generate Dataset

Create Crystal Report.

STEPS:
Right Click Solution Explorer -> Add -> Add New Item -> choose Crystal Report under the Categories (Web Project Items).

Configure the Crystal Report.

STEPS:

Select Report Layout, ProjectData, ADO.NET DataSets
Expand ADO.NET DataSets and select the table
Select the fields

Create a WebForm and drag and drop the CrystalReportViewer control from the Toolbox(General).

Put a textbox and button

Open the Code window of the WebForm and write the following code.

And change the value of the connectionstring variable sqlConn.
Webform1.aspx.cs

using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;

using System.Data.SqlClient;

namespace CrystalReportEg
{
///

public class WebForm1 : System.Web.UI.Page
{
protected CrystalDecisions.Web.CrystalReportViewer CrystalReportViewer1;

protected System.Web.UI.WebControls.TextBox TextBox1;
protected System.Web.UI.WebControls.Button Button1;
public Customer oRpt = null;

private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here

}

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
base.OnInit(e);
oRpt = new Customer();
GenerateReport();
}

///

/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
///

private void InitializeComponent()
{
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);

}
#endregion

private void Button1_Click(object sender, System.EventArgs e)
{
GenerateReport();
}
protected void GenerateReport()
{
SqlConnection sqlConn = new SqlConnection("Server=localhost;uid=sa;password=;initial
catalog=Northwind;");

SqlCommand comd;
comd = new SqlCommand();
comd.Connection = sqlConn;
comd.CommandType = CommandType.StoredProcedure;
comd.CommandText = "up_GetAllCustomer";

comd.Parameters.Add("@Companyname",SqlDbType.VarChar,50);
if(TextBox1.Text.Trim()!="")
comd.Parameters[0].Value=TextBox1.Text;
else
comd.Parameters[0].Value=DBNull.Value;

SqlDataAdapter sqlAdapter = new SqlDataAdapter();
sqlAdapter.SelectCommand = comd;

Dataset1 ds = new Dataset1();
sqlAdapter.Fill(ds, "Customers");

oRpt.SetDataSource (ds);

CrystalReportViewer1.Visible=true;

CrystalReportViewer1.ReportSource = oRpt;
}
}
}

Hope this will give you a clear picture of the web crystal report generation.
