title: Cognos 10 Report Studio: On Page Prompts & Performance
body: <p>I have a report page which displays a crosstab. This is filtered by 5 paramaters. These paramaters are submitted by the user through on page checkbox prompts. </p>
  
  <p>The requirement is to return the data with all values in all paramaters selected on the first run. If I leave default selections blank this behaviour is achieved but all the checkboxes are unchecked which gives misleading feedback to the user. </p>
  
  <p>As an alternative I've manually specified all the values in default selections. However, this has a performance impact. </p>
  
  <p>Does anyone have any alternative suggestions?</p>
  
  <p>I've been looking for a way to specifically link a reprompt button to a value list so only those paramaters are resubmitted (rather than the whole page) but haven't found anything yet. </p>
  
  <p>Thanks in advance - even if the answer is 'no and this is a bad way to go about it'!</p>
