In an existing SSRS 2008 R2 report, I want to have a dynamic selection for users to pick from. The selection for the user would be to click a plus sign in a box. Basically the user could click on an item called product. After the user clicks on product, they would be directed to a new web page. The new web page would look like: + bread + milk + fruit.
The user could click on the + sign in front of 'fruit' in the example listed above. The user will then be taken to another page that lists the type of fruit they can by.
Thus can you tell me and/or show me the following: 1. How to make the plus sign in a box show up, 2. How to make the various subcategories show up after the user clicks on the web page.
However, the visuals would not be as you described with + signs and all. The native interface of SQL Reporting Services is rather limited.
If you want to provide a better user experience, one way would be to create your own Web or Windows user interface with the controls and dropdowns as you see fit, and then use a report viewer control in your GUI to show the report. http://msdn.microsoft.com/en-us/library/ms251671.aspx
the + - sign visualisation is available in data region though which is called drilldown feature in SSRS. You can configure the report to show highest level data ie product etc and have + sign against them then clicking on them showing its children like bread, milk etc which can be repeated further level down until you reach last level.
