Hi, Is there a way to limit maximum number of selections from a multi-valued paramter? Before hitting the View Report button? I have a map using SQL Server Spatial Query and want to limit the maximum number of lines drawn to 100, out of possibly thousands. Thanks

Not via native functionality, however there is a workaround. Have a look at my blog post on it: http://karlberan.wordpress.com/2010/03/19/limit-number-of-multi-select-parameters-in-ssrs-%e2%80%93-custom-code/My Blog "Karl Beran's BI Mumble"
