'Declaration Public ReadOnly Property Parameters As ParameterCollection
public ParameterCollection Parameters {get;}
The parameters collection is automatically populated when the report is started. If parameters are specified in the report's DataSource, they will be added to the collection.
For example, setting your RecordSource to the following SQL adds "Order Date" and "Order ID" to the parameters collection.
"SELECT * FROM orders WHERE OrderDate >= #<%Order Date|Enter Order date|1/1/1995%># AND OrderID > <OrderID|Order ID>"
You can set the parameter values before the report starts or allow ActiveReports to collect the values from the user at run time.
Note: Depending on your data source, you may need to add pound signs around the parameter syntax for dates (as in the "Order Date" example above) or apostrophes around the parameter syntax for strings, i.e. "SELECT * FROM Customers WHERE CustomerID = '<CustomerID>'"
