BindingSource filter with ReportViewer

01 Mar

When binding a BindingSource to a ReportViewer after BindingSource.Filter, it doesn’t display filtered data. The ReportViewer still refers to the underlying data source of the BindingSource regardless of any filtering or sorting the BindingSource applies. It seems to be a bug in .NET. A simple walk around is using another BindingSource to be the bridge between the filtered BindingSource and the ReportViewer. Sample code as follows:

originalBindingSource.Filter = someFilterString
Dim tempBindingSource As New BindingSource(originalBindingSource, "")
Me.ReportViewer1.LocalReport.DataSources(0).Value = tempBindingSource
' ------------------------------------
Me.ReportViewer1.RefreshReport()
