In Visual studio 2005, I using a listbox control to pass and set parameters for my crystal report using a crystal report viewer

So the record selection formula with my parameter field 'ID' is as follows:
{TableA.ID} = {?ID}

Note that the parameter field doesnt have any default values to show via the parameter prompt because the listbox is controlling the parameters

The report works fine for most of my parameters

But, a few of my parameters are null/ blank values (its just how the data is), so the parameter prompt tends to show up.
Instead, if a null parameter is received, how do I make crystal report display a blank page and avoid the parameter prompt?


Please advise

thanks
