如何使用编码运行 rdlc

发布于 2024-09-07 18:53:00 字数 1210 浏览 3 评论 0原文

我创建了一个 rdlc，其中使用数据集作为解决方案资源管理器中的新项目来设计我的报告。从名为 Dataset1 的数据源绑定我的报告后。我已经创建了它的对象并尝试使用编码来填充此数据源。现在，当我运行以下代码时，我没有得到任何结果。

可能是什么问题？

reportViewer1.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local;
LocalReport localReport = reportViewer1.LocalReport;
localReport.DataSources.Clear();
localReport.ReportPath = @"E:\Projects\Manojp\AARFID_SSRS_Report\WindowsFormsApplication1\WindowsFormsApplication1\Local Report\rptTest.rdlc";

// DataSet dataset = new DataSet("AARFID_Report");
DataSet1 ds = new DataSet1();

// fill the Data Set from DataBase.
//ds.Tables.Remove("M_GUEST");
ds.Tables.Clear();
GetData(ref ds);

//
// Create a report data source for the sales order data

ReportDataSource rds = new ReportDataSource();
rds.Name = "AA";
rds.Value = ds.Tables[0];
localReport.DataSources.Add(rds); 
// reportViewer1.LocalReport.DataSources.Add(rds); 


reportViewer1.RefreshReport();
localReport.DataSources.Clear();

GetData() 执行此操作：

connection.Open();
ad.Fill(ds,"M_GUEST");
connection.Close();

在报告视图中，消息显示为：

尚未为数据源“dtaset1_m_guest”提供数据源实例

I have created an rdlc where I have used dataset taken as a new item in solution explorer for designing my report. After binding my report from that datasource which is named as Dataset1. I have created its object and tried to fill this datasource using coding. Now when I runs the following code I am not getting any result.

What can be the issue?

reportViewer1.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local;
LocalReport localReport = reportViewer1.LocalReport;
localReport.DataSources.Clear();
localReport.ReportPath = @"E:\Projects\Manojp\AARFID_SSRS_Report\WindowsFormsApplication1\WindowsFormsApplication1\Local Report\rptTest.rdlc";

// DataSet dataset = new DataSet("AARFID_Report");
DataSet1 ds = new DataSet1();

// fill the Data Set from DataBase.
//ds.Tables.Remove("M_GUEST");
ds.Tables.Clear();
GetData(ref ds);

//
// Create a report data source for the sales order data

ReportDataSource rds = new ReportDataSource();
rds.Name = "AA";
rds.Value = ds.Tables[0];
localReport.DataSources.Add(rds); 
// reportViewer1.LocalReport.DataSources.Add(rds); 


reportViewer1.RefreshReport();
localReport.DataSources.Clear();

GetData() do this:

connection.Open();
ad.Fill(ds,"M_GUEST");
connection.Close();

In the report view a message is shown as:

A data source instance has not been supplied for the data source 'dtaset1_m_guest'

如果绑定中的数据源名为“Dataset1”，那么您在代码中的数据源也应命名相同。

我添加它就像这样完美地执行此操作，如下所示：

 reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("Dataset1", ds.Tables[0]));

If the DataSource in binding is named "Dataset1" then the one you your in code should also name the same.

I add it like this works perfectly do this as below:

 reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("Dataset1", ds.Tables[0]));

当您通过向导在项目中添加 .rdlc 报告时，默认情况下它将数据集名称设为 'DataSet1' 。现在，如果您想动态绑定新数据集，则该数据集的名称必须是“DataSet1”。尝试更改它，并检查 Table[0] 是否包含一些数据（行），其数据类型与“DataSet1”的原始数据类型匹配。如果数据类型不匹配，则数据将不会出现在您的 ReportViewer 中。尝试此代码：-

string exeFolder = (Path.GetDirectoryName(Application.StartupPath)).Substring(0, (Path.GetDirectoryName(Application.StartupPath)).Length - 3);
string reportPath = Path.Combine(exeFolder, @"Reports\SessionReport.rdlc");
Microsoft.Reporting.WinForms.ReportDataSource rds = new Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", ds.Tables[0]);
this.reportViewer1.LocalReport.DataSources.Add(rds);
this.reportViewer1.LocalReport.ReportPath = reportPath;
this.reportViewer1.RefreshReport();

When you add .rdlc report in your project by wizard then by default it take dataset name as 'DataSet1' . Now if you want to bind dynamically new dataset then name of that dataset must be 'DataSet1'. Try change it and also check that Table[0] contains some data(Rows) for which DataType get matched with original dataType of 'DataSet1'. If DataType doesn't matches then data wont come in your ReportViewer. Try this code:-

string exeFolder = (Path.GetDirectoryName(Application.StartupPath)).Substring(0, (Path.GetDirectoryName(Application.StartupPath)).Length - 3);
string reportPath = Path.Combine(exeFolder, @"Reports\SessionReport.rdlc");
Microsoft.Reporting.WinForms.ReportDataSource rds = new Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", ds.Tables[0]);
this.reportViewer1.LocalReport.DataSources.Add(rds);
this.reportViewer1.LocalReport.ReportPath = reportPath;
this.reportViewer1.RefreshReport();
