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

//为FrxDataTable加载数据
private void FillTableWithSampleData(FrxDataTable datatable)
{

SqlDataAdapter da = new SqlDataAdapter("select * from demo_test", conn);
da.Fill(datatable);
}
//为FrxDataSet加载数据
private void FillDataSetWithSampleData(FrxDataSet dataset)
{
SqlConnection conn = new SqlConnection("server=.;database=DEMO;UID=sa;PWD=");
SqlDataAdapter da = new SqlDataAdapter("select top 2 * from demo_test", conn);
da.Fill(dataset,"demo_test");\\demo_test为表名,对应FastReport模板中Memo的名字[demo_test."id"]
}
//加载FrxDataTable
private void button1_Click(object sender, EventArgs e)
{
report = new TfrxReportClass();
report.ClearDatasets();//加这句可以避免重复打开报表提示错误
datatable = new FrxDataTable("demo_test");\\demo_test为表名,对应FastReport模板中Memo的名字[demo_test."id"]
FillTableWithSampleData(datatable);
//report.MainWindowHandle = (int)this.Handle;
report.LoadReportFromFile("demo_test.fr3");
//report.ClearDatasets();
datatable.AssignToReport(true, report);
datatable.AssignToDataBand("MasterData1", report);
report.ShowReport();
}
//加载FrxDataSet
private void button2_Click(object sender, EventArgs e)
{
report = new TfrxReportClass();
report.ClearDatasets(); //加这句可以避免重复打开报表提示错误
dataset = new FrxDataSet();
FillDataSetWithSampleData(dataset);
report.LoadReportFromFile("demo_test.fr3");
dataset.BindToReport(report);
dataset.BindTableToBand("demo_test", report, "MasterData1");
report.ShowReport();
}
//加载Dedigner
private void button3_Click(object sender, EventArgs e)
{
report = new TfrxReportClass();
report.LoadReportFromFile("demo_test.fr3");
report.DesignReport();
}
}
}
