Step1: create new aspx page and insert the following code

<div>
<table width="800" style="background-color:White" border="0" cellpadding="0"
cellspacing="0" align="center">
<tr>
<td style="width:25px"></td>
<td>

<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"
DisplayGroupTree="False" oninit="CrystalReportViewer1_Init" />

</td>
<td></td>
</tr>
</table>

<asp:Button ID="btnReport" runat="server" CausesValidation="False"
onclick="btnReport_Click" Text="View" />

</div>

Step2: go to .aspx.cs page and insert the following code

protected void Page_Load(object sender, EventArgs e)
{

//this.ToolkitScriptManager1.RegisterPostBackControl(this.CrystalReportViewer1);

if (!Page.IsPostBack)
{
CrystalReportViewer1.ReportSource = (ReportDocument)Session["report"];

bindReport();
}
else
{
if (Session["report"] != null)
{
crReportDocument = (ReportDocument)Session["report"];
}

}
}

protected void btnReport_Click(object sender, EventArgs e)
{

bindReport();

}

public void bindReport()
{
string reportFilePath;
DataSet ds = new DataSet();
try
{
// ScriptManager scriptManager = ScriptManager.GetCurrent(this);
//scriptManager.RegisterPostBackControl(this.CrystalReportViewer1);
reportFilePath = Server.MapPath("Reports//rptVouchersReport.rpt"); //this is the folder located in you root directry, change it for your conviniyance
ds=getDataFromTable();// you call the method here to return the dataset of you data which you want to display

if (ds.Tables[0].Rows.Count > 0)
{
crReportDocument.Load(reportFilePath);
crReportDocument.SetDataSource(ds.Tables["report"]);
Session["report"] = crReportDocument;
CrystalReportViewer1.ReportSource = (ReportDocument)Session["report"];
CrystalReportViewer1.DataBind();
CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.HasCrystalLogo = false;
}
else
{
Session["report"] = null;
CrystalReportViewer1.ReportSource = (ReportDocument)Session["report"];

}

}
catch
{
}

}

protected void Page_Init(object sender, EventArgs e)
{
if (Session["report"] != null)
{
CrystalReportViewer1.ReportSource = (ReportDocument)Session["report"];
}
}

protected void CrystalReportViewer1_Init(object sender, EventArgs e)
{

}
