如何在Visual Studio中从数据库中设置Crystal Report Viewer的Picture Control中的动态画面？ [英] How can i set dynamic picture in Picture Control of Crystal Report Viewer from database in Visual Studio?

问题描述

大家好，

我已经在vb.net上设计了水晶报告，我想在我的项目上显示该报告的图片。我在CR上删除了Picture Control，我试图找到这个控件的属性来设置数据库的图片路径，但我没有看到它。有没有人知道这个？

注意：

- 我使用Visual Studio 2008

- CR版本2008



谢谢

推荐答案

您需要将图像列（byte []）添加到表中，添加要报告的列，（不是Picture控件，但是字段）：

Hi,

you need to add image column (byte[]) to the table, add the column to report, (not Picture control, but field) :

data.Tables(0).Columns.Add("img", System.Type.GetType("System.Byte[]"))

' fill the table with pictures from database or file system
'...
'...

' create a report
Dim cr As New CrystalReport1()

' pass a dataset  to a report 
cr.SetDataSource(data.Tables(0))

' pass a reportdocument to the viewer
CrystalReportViewer1.ReportSource = cr

其中数据是您的数据集。

Where "data" is your dataset.
