如何显示在运行时选择的图像？ [英] How to show images that are selected at run time?

问题描述

我的报告查看器现在显示一些嵌入的图像。但是我需要显示一个在运行时创建的图表。我的图表模块（控件）可以创建一个图表，例如Graph.jpg，但它应该在报告生成时加载到报告中。怎么做？

谢谢

解决方案

我的报告在本地呈现，我的数据源是Linq存储过程结果集。我在结果类中添加了一个byte []成员和一个getter方法，为每一行生成图像。我可以将图像作为数据库图像引用，只需指定数据集成员的值。

My report viewer now shows some embedded images. But I need to show a graph which is created at run time. My charting module( control) can  create a graph say Graph.jpg, but it should be loaded into the report at the time of report generation. How to do that?

Thank you

解决方案

My reports render locally and I my datasource is a Linq stored procedure result set. I added a byte[] member and a getter method to the results class that produces the image for each row. I can reference the image as a database image and just assign the value of the dataset member.
