How do you add a listbox as an input parameter UI element in SSRS 2008?

I have to add a listbox/dropdownlist to a report in a Visual Studio Business Intelligence project, allowing users to filter a DataSet by the Id of the entity chosen in the listbox. I heard this was possible, but there is no option to add a listbox in the Toolbox in Visual Studio, and looking at the Report Definition on 开发者_开发百科microsoft.com, there's nothing there about a listbox.

What am I doing wrong here?

I found out how to do what I was tring to do. There is no listbox option, the way I was thinking of it. Instead, if you add a parameter for the report, and use the "available values" section to associate the parameter with, for example, the results of a query, then a listbox/dropdownlist will appear in the header, prompting you to select an item from the list that results from the query.

That's exactly what I wanted to do. I was still thinking in Asp.Net terms though, where a listbox is the same sort of thing as a textbox, for example. I couldn't see why a textbox would be an option in the toolbox, but not somehting like a listbox.

there isn't any listbox or dropdownlist as a built-in control in reporting services. you must have an application (web/win) for this work and pass your data as a parameter to your report.
