c# - 2 つの日付範囲間のデータを表示する方法

Question

データベーステーブルからいくつかのデータを表示しようとしていますが、メッセージが表示されています。

"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."

そしてC#コードは...

DateTime date = Convert.ToDateTime(RadDatePicker1.DbSelectedDate);    
DateTime date1 = Convert.ToDateTime(RadDatePicker2.DbSelectedDate);

    string st = date.ToString("yyyyMMdd");

    string st1 = date1.ToString("yyyyMMdd");


    AttendanceDataSetTableAdapters.tblAtData4TableAdapter adptAtnRange = new AttendanceDataSetTableAdapters.tblAtData4TableAdapter();
    AttendanceDataSet.tblAtData4DataTable tblAtnRange = new AttendanceDataSet.tblAtData4DataTable();

    adptAtnRange.FillAllRange((tblAtnRange), st, st1, RadTextBox1.Text);

    ReportDataSource mds = new ReportDataSource("DataSetByRange", (DataTable)tblAtnRange);

    this.ReportViewer1.LocalReport.DataSources.Clear();
    this.ReportViewer1.LocalReport.ReportPath = Server.MapPath("AttendenceByRange.rdlc");
    //this.ReportViewer1.LocalReport.DataSources.Add(mds);
    this.ReportViewer1.LocalReport.DataSources.Add(mds);
    this.ReportViewer1.LocalReport.Refresh();
