I've seen code that sets up a reportviewer dynamically, like this:

LocalReport.ReportPath = "Rpt1.rdlc"

Dim rdsReport As New ReportDataSource
rdsReport.Name = "Rpt1Data"
rdsReport.Value = dtReport
ReportViewer1.LocalReport.DataSources.Add(rdsReport)

ReportViewer1.LocalReport.Refresh()

I'd like to be able to use this approach, but VS2005 complains if my rdlc does not have a DataSet. Is there a way to set up the dataset in the rdlc so that I don't have to actually wire it up to data, since I need to do that dynamically in code?

Thank you.

Hi,

If you are using the ReportViewer control in local mode, the dataset has to be retrieved through your application code. Then the dataset is just handed to the ReportViewer control - so in that case it does not matter which data source you are using.

For the datasource, you can expose them from the business object class as a dataset/datatable typed object, and just switch your datasource dynamically by adding some logic in your code.

Thanks.
