Hi,

I'm using a multivalue parameter on a web report.  I've set up my data source and previewing the data looks good.  Sometimes the parameter works.  When I first set it up it worked for a long time.  Now it's blank.  The multivalue parameter seems to come and go.  I'd post some sample code but it would probably work.  What info do I need to provide to get some help?  The browser doesn't seem to matter.

Thanks,
Darren

Hello Darren,

It will be best if you can send us a working solution which replicates the problem. If you cannot do so you can send us screenshots to illustrate the issue. To do either of these things you have to open a support ticket as in forums attaching files is not allowed.

Kind regards,

I finally figured it out.  I guess when the report configures the parameters it modifies the constructor to fill the DataSetTableAdapter.  I'm using the _NeedDataSource event since my record sets are too large to filter.  It seems under some circumstances the when you have two or more multiple value parameters some of them get lost.  I'm not quite sure about that since I keep changing things because the report wizard or parameter screen or something keeps changing my code?  I hope that helps.
