I'm creating a report in VS2005 using data from a database. I know how to make a connection and everything else; what's getting me confused is working with parameters.
I generally use the XML code to create parameters for the report after adding my data. I want the parameters from the database to appear in a drop-down box, instead of a text box, and I want a NULL option to appear as well. What is the XML code to import the fields from a specific data table and column, and can I add a nullable option? (I want the user to be able to narrow down options as much as they wish, but to leave out filters when they don't want them. All of the other reports I've viewed with a drop down do not include a nullable otion)
