An error occurred during local report processing in setparameters
提问by Aniket Tendulkar
I am trying to process a local report but getting errors in setparameters. here is the sample code.
我正在尝试处理本地报告，但在 setparameters 中出现错误。这是示例代码。
r.ProcessingMode = ProcessingMode.Local
r.ProcessingMode = ProcessingMode.Local
Dim lr As LocalReport = r.LocalReport
lr.ReportEmbeddedResource = "Gy.Report1.rdlc"
'note report is blank.
'注意报告是空白的。
Dim dss As New DataSet
Dim daa As New SqlDataAdapter("select * from c_inventory", cn)
cn.Open()
daa.Fill(dss, "c_inventory")
cn.Close()
Dim dss1 As New ReportDataSource
dss1.Name = "c_inventory"
dss1.Value = dss.Tables("c_inventory")
lr.DataSources.Add(dss1)
r.RefreshReport()
'Create a report parameter for the sales order number
Dim rpfilled As New ReportParameter()
rpfilled.Name = "filled"
rpfilled.Values.Add("0")
Dim param() As ReportParameter = {rpfilled}
lr.SetParameters(param)
回答by StackTrace
I normally set my report parameters in local processing mode so
我通常在本地处理模式下设置我的报告参数，所以
Dim p As New ReportParameter("myParameterName", param1.ToString())
rptViewer.LocalReport.SetParameters(New () {p})
So try to changing your last 2 lines to
所以尝试将最后两行更改为
Dim param As New ReportParameter("yourReportParametername", rpfilled)
lr.LocalReport.SetParameters(New () {param})
