I’ve wanted to write about this for some time, as it was a pretty tough challenge.
First, some background: A couple years ago, I built a custom SSRS Parameter Viewer Control to replace the one that ships with ASP.NET ReportViewer control. The default prompt area of the ReportViewer was not very visually appealing and selection changes to the parameters themselves often caused full postbacks! L I understand that’s been fixed now with SSRS 2008/R2, but it is still lacking in text lookup and other features that I have since added to my custom control.
This is a pretty long post, so I PDF’d it: SSRS ReportView Chart Caching Issue – Resolved!
