title: Cascading Parameters in SSRS
body: <p>I have a multi select drop down parent parameter (which populates from various other parameters on the report) that I need to get the multiple values of in order to run my actual query to get the report data set. </p>
  
  <p>Whenever I select multiple values from the parent drop down list, it only returns the first row. Also, when I uncheck or check more values, or change the value of the drop down, the result set never changes. </p>
  
  <p>Does anyone know what can be causing this and if it can be fixed? Is this an issue with cascading parameters in SSRS?</p>
  
  <p>Thank you. </p>
