I am using visual studio 2010 and mysql for database and crystal report for reporting.
I want to show report and filter it based on its category. I have tried this tutorial here : http://vb.net-informations.com/crystal-report/vb.net_crystal_report_parameter_string.htm
It works, but only if the parameter already been filled. What I want is, if the parameter empty then report will show all item, else report will show based on the parameter.
How do i do that ?
Here a little detail of my project :
Database field :
- ID
- Category
- Item
Parameter Name in crystal Report :
- fillcategory
Field in visual studio :
- cboCategory [i am using combobox]
