I am trying to pass dataset to subreport in crystal report. Last line of this code gives error object reference error

if (string.IsNullOrEmpty(Convert.ToString(ds)) || ds.Tables[0].Rows.Count == 0)
                    GlobalFormValidations.ShowInformationMsgBox("There Is No Report To Show...");

                var DocReport = new ReportDocument();
                var reportPath = Application.StartupPath + "\\Reports\\" + fileName + ".rpt";

this condition

if (string.IsNullOrEmpty(Convert.ToString(ds)) || ds.Tables[0].Rows.Count == 0)

checks whether ds.tables[1] has records or not but while setting the datasource of the sub report you are using ds.Tables[0].

So there is a possibility that ds.Tables[0] is empty. Please verify.
