title: How to hide RDLC Table Column if no data is present in all the Rows with Expression?
body: <p>I would like to hide the entire column including the header if all the rows under that is null or of no values with expression in an RDLC Report.</p>
  
  <p>I have tried the expression </p>
  
  <pre><code>"=IIF(IsNothing(Fields!de_projectactivityidname.Value), True, False)"
  </code></pre>
  
  <p>inside the "Visibility" of the Column property.</p>
  
  <p>I would like to do this without any report parameters.</p>
  
  <p>any help is appreciated.</p>
