Problem with populating Fast Report via .NET code

I am trying to populate my fast report with dummy data using .NET code

DataTable dt = new DataTable();
dt.Columns.Add("name", typeof(string));
dt.Columns.Add("days", typeof(string));
dt.Columns.Add("court", typeof(string));

dt.Rows.Add("John Doe", "5", "Court A");
dt.Rows.Add("Jane Smith", "10", "Court B");
dt.Rows.Add("Alice Johnson", "7", "Court C");

WebReport1.Report?.Dispose();
WebReport1.Report = new FastReport.Report();

WebReport1.Report.Load(Server.MapPath("~/reports_frx/ReportCourtDuration.frx"));

WebReport1.Report.RegisterData(dt, "Results");
WebReport1.Report.GetDataSource("Results").Enabled = true;

WebReport1.Report.Prepare();
WebReport1.Visible = true;

Also this is my .frx file is which I am trying to populate.

<?xml version="1.0" encoding="utf-8"?>
<Report ScriptLanguage="CSharp" ReportInfo.Created="2025-10-07" ReportInfo.CreatorVersion="1.9.1.0">
  <Dictionary>
    <TableDataSource Name="Results" ReferenceName="Results" DataType="System.Data.DataTable" Enabled="true">
      <Column Name="name" DataType="System.String"/>
      <Column Name="days" DataType="System.String"/>
      <Column Name="court" DataType="System.String"/>
    </TableDataSource>
  </Dictionary>

  <ReportPage Name="Page1">
    <ReportTitleBand Name="ReportTitle1" Width="718.2" Height="37.8" />
    <PageHeaderBand Name="PageHeader1" Top="41.65" Width="718.2" Height="18.9">
      <TextObject Name="Header1" Left="10" Width="200" Height="18.9" Text="Name" Font="Arial,10,Bold" />
      <TextObject Name="Header2" Left="220" Width="100" Height="18.9" Text="Days" Font="Arial,10,Bold" />
      <TextObject Name="Header3" Left="330" Width="100" Height="18.9" Text="Court" Font="Arial,10,Bold" />
    </PageHeaderBand>

    <DataBand Name="Data1" Top="65" Width="718.2" Height="18" DataSource="Results">
      <TextObject Name="Text1" Left="10" Width="200" Height="18" Text="[Results.name]" />
      <TextObject Name="Text2" Left="220" Width="100" Height="18" Text="[Results.days]" />
      <TextObject Name="Text3" Left="330" Width="100" Height="18" Text="[Results.court]" />
    </DataBand>

    <PageFooterBand Name="PageFooter1" Top="90" Width="718.2" Height="18.9" />
  </ReportPage>
</Report>

I have tried several solutions but with no results.

What is my mistake?
