It’s worth mentioning that I don’t use the Crystal Reports extensions for Visual Studio, I have Crystal Server running on the box. I can’t see how this method wouldn’t work through the Visual Studio extensions.

Code Infront

Register the assembly in the top of your aspx page

<%@ Register TagPrefix="cr" Namespace="CrystalDecisions.Web" 
Assembly="CrystalDecisions.Web, Version=11.0.3300.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %>

Place the control where you want it to appear in the page.

<cr:crystalreportviewer id="crReport1" runat="server" hasviewlist="False"
    hastogglegrouptreebutton="False" hassearchbutton="False"
    hasgotopagebutton="False" hasdrillupbutton="False" hascrystallogo="False"
    autodatabind="true" width="350px" displaygrouptree="False"
    height="50px" hyperlinktarget="_blank">

Code Behind

// declare the variables
protected CrystalReportViewer crReport1;
private ReportDocument document1 = new ReportDocument();
private TableLogOnInfos infos1 = new TableLogOnInfos();
private TableLogOnInfo info2 = new TableLogOnInfo();
private ConnectionInfo info1 = new ConnectionInfo();
 
// load the report
document1.Load(Request.PhysicalApplicationPath + "myReport.rpt");
 
// Add the parameters
document1.SetParameterValue("param1", "value1");
document1.SetParameterValue("param2", "value2");
 
//Set the login info for the database
info1.ServerName = ConfigurationSettings.AppSettings["server_name"];
info1.DatabaseName = ConfigurationSettings.AppSettings["database_name"];
info1.UserID = ConfigurationSettings.AppSettings["user_id"];
info1.Password = ConfigurationSettings.AppSettings["password"];
Tables tables1 = document1.Database.Tables;
 
//Apply login info to the report
foreach (CrystalDecisions.CrystalReports.Engine.Table table1 in tables1)
{
    info2 = table1.LogOnInfo;
    info2.ConnectionInfo = info1;
    table1.ApplyLogOnInfo(info2);
}
 
// Bind the report
crReport1.ReportSource = document1;
crReport1.DataBind();

You also need to remember to close the document after it has been rendered to free up memory. This should ideally be done in the Page_Unload method. See this post on MSDN for more information on why it should be placed in Page_Unload.
