protected void btnAuthenticateAndPrint_Click(object sender, EventArgs args)
    {
        try
        {
            
            //Getting Values from grid
            LinkButton lb = (LinkButton)sender;
            GridViewRow row = (GridViewRow)lb.NamingContainer;
            Label lbOrderID = row.FindControl("lbOrderID") as Label;
            int OrderId = Convert.ToInt32(lbOrderID.Text);
            da = new SqlDataAdapter("Get_PODetails", con);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;
            da.SelectCommand.Parameters.AddWithValue("@MPDI_ID", OrderId);
            ds = new DataSet();
            da.Fill(ds, "PO");
            if (ds.Tables["PO"].Rows.Count > 0)
            {
                lblPOId.Text=ds.Tables["PO"].Rows[0]["MPDI_ID"].ToString();
                lblVendid.Text = ds.Tables["PO"].Rows[0]["MVDI_ID"].ToString();
                lblBranch.Text = ds.Tables["PO"].Rows[0]["MBRI_ID"].ToString();
                lblDate.Text = Convert.ToDateTime(ds.Tables["PO"].Rows[0]["MPDI_Date"]).ToString("dd-MM-yyyy");
            }
 
            //SSRS Report Print
            rs = new RSWebService.ReportingService2005();
            rsExec = new REWebService.ReportExecutionService();
            rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

Hi Vinay,

You can extract the report like the following.

// First read in the report into memory.

string strReportUser = "RSUserName";
string strReportUserPW = "MySecretPassword";
string strReportUserDomain = "DomainName";

string sTargetURL = "http://SqlServer/ReportServer?" +
   "/MyReportFolder/Report1&rs:Command=Render&rs:format=PDF&ReportParam=" +
   ParamValue;

HttpWebRequest req =
      (HttpWebRequest)WebRequest.Create( sTargetURL );
req.PreAuthenticate = true;
req.Credentials = new System.Net.NetworkCredential(
    strReportUser,
    strReportUserPW,
    strReportUserDomain );

HttpWebResponse HttpWResp = (HttpWebResponse)req.GetResponse();

Stream fStream = HttpWResp.GetResponseStream();

HttpWResp.Close();



//Now turn around and send this as the response..
byte[] fileBytes = ReadFully( fStream );
// Could save to a database or file here as well.

Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader(
    "content-disposition",
    "attachment; filename=\"Report For " +
        ParamValue + ".pdf\"" );
Response.BinaryWrite( fileBytes );
Response.Flush();
Response.End();
ReadFully is

public static byte[] ReadFully( Stream input )
{
   using ( MemoryStream ms = new MemoryStream() )
   {
      input.CopyTo( ms );
      return ms.ToArray();
   }
}

You can refer the following link too.
