Is FindBy<Key> Method applicable to design time dataset
Hi,
I created a dataset during run time and assigned it to the datagrid. But i cant get the FindBy<Key> method to work. During design time, i got a error "dtProdHdr is not a member of System.Data.DataSet" error Is it that FindBy<Key> method is used only for DataSet generated during design time by the wizard? Can i actually use FindBy<Key> method if i am using a design time created dataset? below is a sample of my codes Shared dsProdInfo As DataSet Shared dtProdHdr As DataTable Shared dtProdDtl As DataTable Dim myDataRow As DataRow Sub myFunction() dsProdInfo.DataSetName = "dsProdInfo" dtProdHdr = New DataTable("dtProdHdr") dtProdHdr.Columns.Add("PROD_CAT") dtProdHdr.Columns.Add("PROD_TYPE") dtProdHdr.Columns.Add("KIT_NO") dtProdHdr.Columns.Add("PROD_DESC") dsProdInfo.Tables.Add(dtProdHdr) Dim dr as DataRow ' Error "dtProdHdr is not a member of System.Data.DataSet" occurs below dr = dsProdInfo.dtProdHdr.FindByPROD_DET_ID() End Sub Thanks for any advice Keith Keith |
