previous code:
if(!Ispostback)
{
DataSet dtUser = new DataSet();
SqlCommand cmd = dcon.CreateCommand("Get_AllUser", true);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dtUser);
if (dtUser.Tables[0].Rows.Count > 0)
{
dtUser.Tables[0].Columns.Add("S_No");
for (int i = 0; i <= dtUser.Tables[0].Rows.Count - 1; i++)
{
dtUser.Tables[0].Rows[i]["S_No"] = i + 1;
}
}
ReportDocument report = new ReportDocument();
dsUserEntry ds = new dsUserEntry();
ds.Tables[0].Merge(dtUser.Tables[0]);

report.Load(Server.MapPath("RepotUserEntry.rpt"));
report.SetDataSource(ds);
CrystalReportViewer1.ReportSource = report;
}
catch (Exception ex) { throw ex; }
finally { dcon.CloseConnection(); }
}

just remove if() statement and problem solved.
