水晶报表中的数据未支付 [英] Data Not dispaying in crystal report

问题描述

ReportDocument repdoc = new ReportDocument();
    DataSet1 ds = new DataSet1();
    DataTable dt = new DataTable();
       
    dt.TableName = "Attendance_Master";
    SqlDataAdapter adap = new SqlDataAdapter("select * from Attendance_Master", con);
    adap.Fill(ds);
     ds.Tables[0].Merge(dt);
     repdoc.Load(Server.MapPath("CrystalReport.rpt"));

     repdoc.SetDataSource(ds);
     CrystalReportViewer1.ReportSource = repdoc;

我做了类似上面的代码，但是数据没有显示在Web应用程序中.
如果某个地方我错了，请放手.

I did code something like above but data is not displaying in a web application.
Please let if I am wrong somewhere.

推荐答案

昨天我已经回答了类似的问题.

好，尝试我的建议....

• 验证报告中的数据库
• 确认您在数据集中或数据表中有数据
• 为数据集&数据表与报表中的数据相同.
如果报表中的表名称为Table1，则您的代码应如下所示.

Yesterday I have answered similar question.

OK Try my suggestions....

• Verify database in the report
• Confirm you have data in the dataset or datatable
• Give the name for Dataset & Datatable same as in the report.
If the table name is Table1 in report then your code should be like below.

DataTable dt = new DataTable("Table1");

与数据集也相同.
如果报表中的数据集名称为Dataset1，则您的代码应如下所示.

Also the same to dataset.
If the dataset name is Dataset1 in report then your code should be like below.

DataSet ds = new DataSet1("Dataset1");

更改此行:

Change this line:

repdoc.SetDataSource(ds);

到

to

repdoc.SetDataSource(ds.Tables[0]);
