无法在Crystal报表中添加参数字段

Question

I am developing a windows application and am using crystal reports in it.

I am trying to add the parameter field in it, however, when I click on the OK button, it is just not working.

Am I missing anything out?

Answer 1

我已经卸载并安装了Crystal Reports，现在可以正常使用了。。。

Answer 2

There could be 2 possiblities.

1) Just checked on my PC, just be Right Clicking Parameters -> Add -> Leaving everything as is (defaults) I am able to create a parameter. You must have changed some setting inside. Use defaults to confirm that you are able to create one.

2) You are missing the Value Field . This field specifies CR which database field to work upon when the parameter is used. The drop-down will list all the database fields available for use.

Besides, here are few tutorials that explain how to use parameters that might guide you.
