水晶报表参数 [英] Crystal reports parameters

问题描述

朋友，

我正在使用C#使用Windows应用程序.由于对Crystal Report还是陌生的，我对此表示怀疑.
我正在通过传递两个参数来显示数据集中的报告.
传递完这两个参数后，我将数据绑定到数据集中.代码在下面给出

Friends ,

I am working with windows application with C#.As i am new to crystal reports am having a doubt.
I am displaying the report from dataset by passing two parameters.
After passing these two parameters i am binding the data into a dataset. The code is given below

Dataset ds1=new Dataset();
rptwithItemDetails cr = new .rptwithItemDetails();
cr.SetDataSource(ds1.Tables[0]);
crystalReportViewer1.ReportSource = cr;
crystalReportViewer1.Refresh();

因此，当报表加载时，将从数据集中加载.
我的要求是我必须在每个报告(4个字段)中设置一些报告标题.
因此，我正在从数据库表中获取该详细信息，并将其加载到另一个数据集中，例如"ds2".

如何将数据集中的值作为参数设置报表标题.

还是我可以选择其他选项? (请注意，报告标题具有四个字段，这些字段是从数据库表中提取的)
请帮帮我.
提前非常感谢.

So when the report loads it will load from the dataset.
My requirement is that i have to set some report heading in every report(4 fields).
So i am fetching that details from my database table and loaded into another dataset say ''ds2''.

How to pass that values in the dataset as parameters for setting report heading.

Or can i choose any other option? (Note that the report heading have four fields which is fetching from database table)
Please help me .
Thanks a lot in advance.

推荐答案

您可以在报表中使用参数

或


在报表标题中添加一个文本框.
将文本"框的名称"更改为"txtHead"

现在在您的应用程序中编写这些代码

You can use Parameter in report

Or


Add a Text box in the header of the report.
Change the "Name" of the Text box to say "txtHead"

Now in your application write those code

Dim objText As CrystalDecisions.CrystalReports.Engine.TextObject
objText = rptReport.Section4.ReportObjects("txtHead")
objText.Text = ds2.tables(0).rows(0)("HEADER")

请注意，此代码在VB.Net中.请以您的方式将其转换为C#

Note this code is in VB.Net. Please convert it in C# in your way
