问题描述
亲爱的，
我有一个包含多个子报告的水晶报告。我想与c＃联系。但是有一个问题是两个子报告链接没有得到。
我有4个用于查询的命令。所有都与一个主要命令链接。
i使用的主要代码如下：
Dear All,
I have one crystal report with multiple Subreport. and I want to link with the c#. but there is a problem that two sub report link is not getting.
I have 4 command used for query. and all are link with one main command.
i used the main code as below :

to_date12 = Request.QueryString["selected_date2"];

对此有任何帮助。
提前致谢。

any help for this.
Thanks in advance.

推荐答案
如果参数有value NULL将其设置为DBNull.Value。 NULL值参数不会发送到DBNull.Value发送到数据库的数据库。
if a Parameter has the value NULL set it to DBNull.Value. A NULL valued parameter is not send to the database where a DBNull.Value is send to the database.
这篇关于子报告参数未设置的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
