Dim dsTemp As New ProductGridDS
obj = New InventoryBusiness.ProductBusiness
dsTemp = obj.GetProductInfo() 'retrieve your data here in dataset
Dim rds As ReportDataSource
rds = New ReportDataSource("ProductGridDS_ProductGridInfo", dsTemp.Tables(0)) 'report name =ProductGridDS_ProductGridInfo
ReportViewer1.LocalReport.DataSources.Clear()
ReportViewer1.LocalReport.DataSources.Add(rds)
