Hi
you have not mansion namespace in beginning of the code block

Try this.

C#

using CrystalDecisions.CrystalReports.Engine;

// This is for CrystalReport "ReportDocument" keyword

if above line of code not work then you should have to add dll or name space to your project or install crystal report.

Hope this will Help you.

Don't forgot to mark this as solution if it is.

Happy Codding...

{
List articles = QueryList("select * from [product] where [ID] = " + id.ToString());

// Only return the first record.
if (articles.Count > 0)
{
return articles[0];
}
return null;

Solution 2

rpt1 custReport = new rpt1(); You can't use the rpt1 directly..

try like this

{
ReportDocument rpt = new ReportDocument();
rpt.Load(@"C:\rp1.rpt");
rpt.Database.Tables[0].SetDataSource(ds_xml);
crystalReportViewer1.ReportSource = rpt;
}
