Get Parameters properties so I can dynamically build a parameters entry screen

Hi

I want to dynamically build an ASP.NET page to allow the user to select values for parameters on a report.

I could keep details of all the parameters in a DB table so I would then know what controls and values to program for on the parameters entry page.

But I would prefer to be able to interrogate the parameters of the selected report direct form the report object itself.

Can you tell me how I can get the details and all properties of parameters on a report pls. If indeed it is possible to do that.

I would need details like name, type, permissible values, single/multiple/range of values etc.

Thanks

Mark
