Vb.net Crystal report通过分配给报表的特定记录显示表的所有记录
我正在开发一个windows应用程序。我使用的是Crystal Reports,它运行得非常完美。我的问题是,Crystal report没有按照查询返回的记录显示记录 我已经编写了根据用户输入获取记录的查询。但当我将集合绑定到报表时,它会显示数据库中存在的所有记录,而不是集合中的记录 还有一件事,它在添加参数字段之前工作得很好。如果我使用以下代码行:Vb.net Crystal report通过分配给报表的特定记录显示表的所有记录,vb.net,crystal-reports,crystal-reports-2008,Vb.net,Crystal Reports,Crystal Reports 2008,我正在开发一个windows应用程序。我使用的是Crystal Reports,它运行得非常完美。我的问题是,Crystal report没有按照查询返回的记录显示记录 我已经编写了根据用户输入获取记录的查询。但当我将集合绑定到报表时,它会显示数据库中存在的所有记录,而不是集合中的记录 还有一件事,它在添加参数字段之前工作得很好。如果我使用以下代码行: cr.SetDataSource(oBatches) 它的工作状态,只显示集合中的记录,但提示手动输入参数。下面是代码 Private Sub
