        public string VendorItemNo_ { get; set; }
        public string CrossRefNo_ { get; set; }
        public string SelectedLabel { get; set; }

        private Microsoft.Reporting.WinForms.ReportViewer reportViewer1;

        public Window1()

            InitializeComponent();

            Labels = new List<string>

                "MetalX"
            };

            this.

            reportViewer1.Size = new System.Drawing.Size(667, 439);
            reportViewer1.TabIndex = 0;

            reportViewer1.LocalReport.SetParameters(umt);
            reportViewer1.LocalReport.SetParameters(crn);
            reportViewer1.RefreshReport();

CodePudding user response：

if someone has same problem it's solution is hard to find but easy, just open your rdlc report in notepad and change Report xmlns to this.

<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" "http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

hope it helps.
