Report Parameters and AllowBlank

[fabio bongiovanni]

Hello and thanks in advice
i'm evaluating the reporting tool.

I've defined a report with 4 text parameter with allowblank setted to true.

In vs2008 when i test the report all the 4 parameter appear with the red asterisk on the right as they are mandatory.
also i can click preview without setting some value to all the parameters.

first question, how can i make the parameter "optional" (without using allownull is better), i mean the user open the report 
click on just one parameter set some text and click preview?

second question, is there any way to force the load of the report  data just on preview click and not on the loading of the container?

is there any best practice about the conditional showing of column in report? i mean based on a user selection showing some column and hiding some other column.

Regards

Fabio
