title: Setting parameter value dependently on the group in rdlc report C#
body: <p>Is it possible to change the parameter value dependently on the group that the parameter is in. This is the case. My report gets grouped by serial numbers of items and I would like to display some additional informations in the group's first row - I use that row as a certain header. Of course that informations are different for each value, so how can I change them depending on that value. Let me give you an example - let's say that item under serial number 1111 is a computer and I track when it was used - when I display my report the group looks like this.</p>
  
  <pre><code>1111
       Logged on | Logged off
            Data      Data
              .         .
              .         .  
  </code></pre>
  
  <p>Let's say that another item is a printer, and it has a serial number is 2222. When I display the report for both items (the individual reports work just fine) it looks like this:</p>
  
  <pre><code>1111         [MyParameter]
           Logged on  |  Logged off
            DateTime      DateTime
                  .         .
                  .         . 
  [Page break]
  
  2222      [MyParameter]
          PrintingStarted | PrintingEnded
             DateTime          DateTime    
                 .                .
                 .                .    
  </code></pre>
  
  <p>I want MyParameter to say "Computer" in the 1111 group and "Printer" in 2222 group. How can I achieve this?
  Thanks</p>
