如何在ASP .NET中创建拖放标签报表

using Microsoft.Reporting.WebForms;

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        // 设置报表文件路径
        string reportPath = Server.MapPath("~/Reports/YourReport.rdlc");

        // 创建报表数据源
        ReportDataSource reportDataSource = new ReportDataSource();
        reportDataSource.Name = "YourDataSourceName";
        reportDataSource.Value = YourDataSource;

        // 清除现有的报表数据源
        ReportViewer1.LocalReport.DataSources.Clear();

        // 添加报表数据源
        ReportViewer1.LocalReport.DataSources.Add(reportDataSource);

        // 设置报表文件路径
        ReportViewer1.LocalReport.ReportPath = reportPath;

        // 刷新报表视图
        ReportViewer1.LocalReport.Refresh();
    }
}
