Hello,

The DataSource Components do not support MultiValue Report Parameter for Stored Procedures because it is based on ADO.NET and does not allow you to pass a collection of values (set, array). The SqlDataSource component supports parametrized SQL queries by associating the parameters you add to the Parameters collection with placeholders in the SelectCommand query. Parameter values can be evaluated with any expression which conforms to the common expression syntax supported by the reporting engine. This grants you a great deal of flexibility on how you can supply your SQL queries with parameters. Unfortunately the above approach is not applicable for stored procedures.

As a workaround our suggestion is to set the SqlDataSource parameter to a comma separated string of the values. I have attached a sample report as an example. In order to run it you will need the AdventureWorks database that came with your installation of Telerik Reporting. Additionally you will need GetByProductNames stored procedure:

USE [AdventureWorks]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[GetByProductNames]
@Names nvarchar(MAX)
AS
BEGIN
        SELECT p.ProductID, p.Name, p.Color FROM Production.Product AS p WHERE CHARINDEX( ',' + p.Name + ',', ',' + @Names + ',' ) > 0

END
