ASP Crystal报告该报告没有表格

Question

I am trying to make a program where I put the data of a Datatable in a Crystal Report. Here is the code:

ReportDocument report_doc = new ReportDocument();
report_doc.Load(Server.MapPath("Trtp.rpt"));

string[] columns = new string[] { "col1", "col2", "col3", "col110", "col111" };

DataTable dt = new DataTable();
int count = columns.Count();
for (int i = 0; i < count; i++)
   dt.Columns.Add(columns[i], typeof(string));

myConnection.comm.CommandText = @"select col1,col2,col3.col110,col111 from TabledataT where " + query;
myConnection.reader = myConnection.comm.ExecuteReader();
dt.Load(myConnection.reader);

DataSet ds = new DataSet();
ds.Tables.Add(dt);
report_doc.SetDataSource(ds.Tables[0]);

CrystalReportViewer1.ReportSource = report_doc;
CrystalReportViewer1.RefreshReport();

In the aspx page :

<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true" />

Trtp.rpt I have selected blank

Error is on this line

report_doc.SetDataSource(ds.Tables[0]);

Error :

The report has no tables

This is the first time I am trying to create the program which uses crystal report, so dont have much knowledge about it.

Why I am getting this error ?

Thanks

I got the working program. I need to create a dataset page with datatable with columns in it. Now Bind the Dataset to the Crystal report to make it working.
