[英]BIRT dynamic image url - cannot get access to data columns
I am trying to display different images based on data returned. 我试图根据返回的数据显示不同的图像。 I am running into the following issues
我遇到以下问题
DataSet is not available on the image control for me to make decisions based on the column information. 图像控件上没有DataSet,我无法根据列信息进行决策。 I am using a grid layout (no tables)... Think of a letter
我正在使用网格布局(没有表格)...想想一个字母
I tried to create report level variables and assign it the value from dataset during the onFetch event. 我尝试创建报告级别的变量,并在onFetch事件期间从数据集中为其分配值。 However, that assignment does not happen.
但是,该分配不会发生。
I have tried both 我都尝试过
rptvar = dataSetRow["colname"]
rptvar = Row["colname"]
I have confirmed that onFetch event does get called using Javascript debugging (see http://www.lebirtexpert.com/wordpress/2010/08/ ) 我已经确认onFetch事件确实是使用Java脚本调试调用的(请参阅http://www.lebirtexpert.com/wordpress/2010/08/ )
Please let me know how to access dataset columns to dynamically create the image URI 请让我知道如何访问数据集列以动态创建图像URI
