I came across an exception when trying to use the Report Filter area with data that contains blank (DBNull) values. It looks like the control tries to build a distinct list of values to show in the filter's drop-down, but throws an exception if one of the values is blank. I attached a ZIP file with a Visual Studio project that demonstrates the issue, and included a Word file to describe how to reproduce the error. Any assistance is greatly appreciated. Thank you.
