Creating a multi-option parameter report for SQL Server Reporting Services

I have a reporting requirement where users want to enter report parameters by either selecting values from a dropdown list or entering To and From range values.  How can I do this in a Reporting Services report?


This tip assumes that you have experience building a simple SSRS report and T-SQL skills. In my previous tips I have explained optional query parameters and cascaded report parameters in SSRS, it is recommended to read these tips as well.

In SSRS we can't enable or disable report parameters based on other parameter values. If we have a report parameter, then we have to provide a value. SSRS doesn't provide any functionality to choose query parameters from report parameters, but we have a workaround.

How to use a multi valued comma delimited input parameter for an SSRS report

You have a requirement where users want to filter report data in SQL Server Reporting Services by entering a list of comma delimited values instead of choosing from a drop down list.  In this tip I will show how this can be completed with Reporting Services.

In this tip we will show how to pass multiple values from a user input report parameter to a query parameter in SQL Server Reporting Services. I will use the AdventureWorksDW2008R2 sample database for SQL Server and SQL Server 2012 Reporting Services to demonstrate the solution.
