I get the error "BC30311: Value of type 'System.Data.DataView' cannot be converted to '1-dimensional array of System.Data.DataView'." whith the below
dvholidays = New DataView(dtholidays, "DATEPART(YEAR, Date) = " & e.Day.Date.Year & " AND " & "DATEPART(MONTH, Date) = " & e.Day.Date.Month, "", DataViewRowState.CurrentRows)
