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

    public partial class Form1 : Form
    {
        TfrxReportClass report;
        FrxDataTable datatable;
        FrxDataSet dataset;

        public Form1()
        {
            InitializeComponent();
        }
	//为FrxDataTable加载数据
        private void FillTableWithSampleData(FrxDataTable datatable)
        {
            SqlConnection conn = new SqlConnection("server=.;database=DEMO;UID=sa;PWD=");
            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();
        }
    }
