Telerik 报表设计器独立版 - WPF - 报表参数值无效

Question

我使用 Telerik Report Designer Standalone 和 sqlDataSource1 设置创建了一个报告，其中的 ReportParameters 如下所示：

在我的 C# 项目中的代码设置中并将参数作为 Int32 发送

    var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
    // set any deviceInfo settings if necessary
    var deviceInfo = new System.Collections.Hashtable();
    var reportSource = new Telerik.Reporting.UriReportSource();
    var directory = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
    var value = Convert.ToInt32(numericExportarPdf.Value);
    reportSource.Uri = "Report.trdp";
    reportSource.Parameters.Add("NRO_TICKET", value);
    Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);
    if (result.HasErrors) return;
    string fileName = result.DocumentName + "." + result.Extension;
    string path = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
    string filePath = Path.Combine(path, fileName);
    using FileStream fs = new FileStream(filePath, FileMode.Create);
    fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);

我收到以下错误：

Telerik.Reporting.Processing.CancelProcessingException: An error has occurred while processing the report. Processing canceled. Check the InnerException for more information.
 ---> System.Exception: Invalid value of report parameter 'NRO_TICKET'.

如果我删除参数，报告工作正常，我添加了对 Decimal Type 值的更改，因为我的数据库引擎是 MS-SQL 2022 Express。我添加了过滤器并得到了同样的错误。我不知道该怎么办了 我缺少什么

我通过删除旧的 sqlDataSource1 创建一个新的并验证参数值是否已正确分配来解决我的问题。
