Report Parameters

Report parameters expose AvailableValues , which represents the valid set of value/label pairs that the end user can choose from.

The AvailableValues.ValueMember and AvailableValues.DisplayMember are usually names of columns from the AvailableValues.DataSource , but sometimes you may need to use an expression to combine values from more columns as values/labels of the parameters. Expressions are also valid ValueMember/DisplayMembers, for example:

='Mr. ' + Fields.LastName + ', ' + Fields.FirstName

You may also use embedded expressions:

Mr. {Fields.LastName}, {Fields.FirstName}
