FastReport动态绑定只显示一条数据。

Posted 2020-10-22 ZGJ

产生这个问题的原因是因为需要把Band绑定DataSource.有两种方法

(1)DataBand data = report1.Report.FindObject("Data1") as DataBand;

data.DataSource = report1.Report.GetDataSource("Items");

(2)将report1.Show();改成report1.Design();然后选择数据源，然后保存报表。再把report1.Design()替换成report1.Show();
