Firstly - may fantastic tools! I have been working with the ASP.Net and the ease of development and manuals are so good I am about to get the order placed!
Based on this I have been looking at the reporting tool and I have hit a minor problem with trying to define a list of values for filtering (which I would like to do by querying my database).
So far I generated a report that I can filter using a value typed into a text box which works fine however it would be much easier for my users if this value were chosen from a dropdown list (much like the orders example in your excellent demonstration). Ideally this would be populated from a simple query to my SQL server
To this end I selected Filters -> new, picked the parameter I wished to filter on and in "values" selected <new report parameter>. In the available values I set up a new data source that returns the ID I wish to filter on and the text description to show. The query executes OK and all is fine!
When however in the Report Parameter Editor I select 'Display member' (which I assume would display the text), Filters, Sorting or Value member I get the same error of 'The service Teletik.Reporting.IDataItem already exists in the service container. Parameter name: service Type"
Any help you can offer would be much appreciated as this would be much appreciated (I am working in vb.net)
