title: SSRS 2008 - How to hide row group column with user-defined grouping?
body: <p>I have a report that we allow the user to choose a field to group on. This is a parameter and the grouping works properly. </p>
  
  <p>However, if no grouping is selected (the default case), the row group column is still displayed. You can hide static columns by setting a visibility expression, but I can't right-click and hide the row group column whenever no grouping has been set. </p>
  
  <p>How can I hide the row group column in SSRS 2008 when the users haven't chosen a field to group on BUT still display it when they have?</p>
