title: how to display multivalued parameter value in SSRS text box
body: <p>I am having a multivalued parameter 'client',i have almost 60 values in the client parameter,my requirement is display the  selected client values in the header text box but when i select 'SELECT ALL' option in the parameter i should display just 'ALL' rather than displaying all the 60 values.</p>
  
  <p>I am using the below expression to display parameter values which is working fine</p>
  
  <pre><code>="For Client -" &amp; Join(Parameters!Client.Value, ",")
  </code></pre>
  
  <p>now how can i display 'ALL' rather than displaying all the client values when i select 'Select ALL' option?</p>
