FastReport studio 动态加载数据集

  FastReport studio 动态加载数据集
测试使用的FastReport Studio 版本为4.6.80

先引用FastReport.dll

然后把C:\Program Files\FastReports\FastReport Studio Trial\Examples\VisualC#.NET\DataSetDemo目录下的

FrxDataSet.cs

FrxDataTable.cs

FrxDataTable.resx

复制到解决方案中(切记要将这三个文件代码中的命名空间更改为自己程序的命名)

SQLServer数据库,表名demo_test  有三个字段 id(int),name(char),onemorename(char)

FastReport报表demo_test.fr3中有三个memo

[demo_test."id"]        DataField属性 id

[demo_test."name"]        DataField属性 name

[demo_test."onemorename"]        DataField 属性 onemorename

以下是我根据DataSetDemo写的代码,在VS2005中测试通过
