运行时数据源绑定和钻取报表数据绑定
本帖最后由 dof 于 2016-10-18 15:27 编辑主要核心使用到了LocateDataSource事件，并根据数据集的名称决定加载什么数据，核心代码：

WinForms Viewer 版本源码下载：
public partial class Index : System.Web.UI.Page

GrapeCity.ActiveReports.PageReport report = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("RdlReport1.rdlx")));
report.Document.LocateDataSource += new GrapeCity.ActiveReports.LocateDataSourceEventHandler(Document_LocateDataSource);
WebViewer1.Report = report;
}
void Document_LocateDataSource(object sender, GrapeCity.ActiveReports.LocateDataSourceEventArgs args)

有html5运行时数据源绑定的demo吗？ 有html5运行时数据源绑定的demo吗？ ziliuxing2008 发表于 2016-10-31 10:19
有html5运行时数据源绑定的demo吗？
有的，请参考博客：http://blog.gcpowertools.com.cn/post/html5DataSourceRunTime.aspx 出现如下错误，请问如何解决？ 您好，您这是数据源的绑定有问题。我给您一个关于html5运行时数据源绑定的demo您参考下！首先Htm5绑定动态数据源，需要自己重新定义Web服务，或者自己重新定义一个Web服务，然后URL绑定的时候绑定新定义的Web服务。
附件中的demo的Webform1.aspx是用的Html5动态绑定数据源
你好，前后端分离，用户在线编辑模板，保存模板，然后通过后台接口提供的所有数据，用户选择模板，预览、打印，有DEMO吗？ 您好你说的用户在线编辑模板，你的项目 是B/S 项目还是C/S项目。关于动态数据源绑定你可以参考这个这一系列的demo：https://gcdn.grapecity.com.cn/forum.php?mod=viewthread&tid=48785&extra=page%3D1
集成编辑器的话你可以看着两个博客：https://gcdn.grapecity.com.cn/forum.php?mod=viewthread&tid=55211&extra=page%3D2
