I need to dynamically provide a ConnectionString to a .trdp at runtime.
I've tried to use a parameter and a binding as stated here: https://docs.telerik.com/reporting/knowledge-base/how-to-pass-connectionstring-to-report-dynamically-through-report-parameter
but I can't get it to work. Without the parameter and binding, the existing dataSource works fine in preview. I'm using Standalone Report Designer 126.96.36.1993. When I add the parameter and binding, and put the connection string value in the parameter input box during preview, I get an error. See the attached picture that shows all settings.
