Hi,
First make sure that you have not saved data with the report. Open the report and unchecked the small check box on the left top corner. Save it.
Make sure that dataset is not empty.
Try with this code sample which works for me:
OleDbConnection conn = new OleDbConnection("Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Password=sa;Initial Catalog=Northwind;Data Source=Server");
OleDbDataAdapter adpt=new OleDbDataAdapter("Select Orders.CustomerID,Orders.EmployeeId,Orders.OrderID,Orders.OrderDate,[order details].productid,[Order Details].UnitPrice,[Order Details].Quantity from [Order Details], Orders Where [Order Details].OrderID = Orders.OrderID",conn);
DataSet ds= new DataSet();
adpt.Fill(ds);
// USE THIS TO GET THE XML FILE TO CHECK FOR DATA AND Dataset SchemaContents
//ds.WriteXml("c:\\temp\\myData1.xml",XmlWriteMode.WriteSchema);
ReportDocument rd = new ReportDocument();
rd.Load("c:\\temp\\ADOReport.rpt");
rd.SetDataSource(ds);
CrystalReportViewer1.ReportSource=rd;
Helps?
