title: Report Data Disappears on Postback
body: <p>I currently have a reporting services project that is displayed as part of an ASP.NET application.  I have one report that has 2 datetime parameters.  When I type in the textbox some sort of date, nothing appears to happen, but if I click on the little calendar icon and select a date, the page will then post back, and the data that used to show is now gone.  Is there a way to prevent this?  After I hit the "View Report" button, it runs the report with the new parameter, but my users are a bit skittish and if the report disappears on them, they will call the helpline in a full-blown panic.</p>
  
  <p>Help save a developer from irate and panicked users?</p>
  
  <p>Thanks in advance.</p>
