I've been looking everywhere but can't find a solution:
I created a report parameter (display type "combo box"; type Integer)
that allows null values.
Is there a way to specify how the ReportViewer displays the null value
in the select box?
Right now it shows a value stating "null value", which is not acceptable
for a real world app.
Can I specify a display text for the null value?
Alternatively, can I set a default value (like "-1") that doesn't
correspond with any value in the combo box and specify a display text
for it (I assume this is even less likely to work)?
Here is what I am trying to do:
I have a Cascading Parameter that collects City - Street - Building info.
I want to be able to leave the Building info blank or even the Street
and Building info. Right now the ReportViewer combo box displays a "null
value" entry, but I need it to say something more meaningful (like 'all
streets', or just 'all').
