问题描述

I am trying to develop client side report in visual studio 2012. My report is working fine with different selection criteria variables. I am getting error while multi selected list values in filters.

In query in need id as SkillTargetID IN (@AgentList). when I pass single value as 5000 its working fine and showing records. But when I pass multiple values as 5000,5001,5002 etc then got error. [An error has orrcurred during report processing. cannot crate a connection to data source 'MyDataSource'. Conversion failed when converting to nvarchar value '5000,5001,5002' to data type int.]

I had tried with

5000,5001,5002

'5000','5001','5002'

(5000,5001,5002)

('5000'),('5001'),('5002')

Any suggestion to pass multiple values to report viewer. I am trying this on visual studio 2012, Sql server 2008 r2 and .net framework 4.5.

推荐答案

Sill I couldn't find any proper solution but I solve my problem by changing DataSource SelectCommand query. On report refresh button_click I just change MyDataSource.SelectCommand query as

string AgentIds = "5000,5001,5002";
        MyDataSource.SelectComamnd = "Select * from Agent where AgentId IN ('" + AgentIds + "')";
        ReportViewer1.LocalReport.Refresh();
and it works. If anyone find a batter solution to add multiple values to DataSource variable then please update me.
