Add to a dataset

I am getting an error "there is no postion in row 0"    when I try to perform the action   DsmhcpTreatmentPlan1.Tables(0).Rows(DataGrid2.CurrentCell.RowNumber).Item(4) = lngpatientid  

How can I fix this please.  

Thank you

I do not have any records in the dataset and would need to add one I'm guessing.  The code below does not work it states.   Add is not a member of system.data.datatable

  Dim rowTemp As DataRow
            rowTemp = DsmhcpTreatmentPlan1.Tables(0).NewRow()
            rowTemp.Item("lngPatientid") = lngpatientid
            DsmhcpTreatmentPlan1.Tables(0).Add(rowTemp)
0

You're close:

  Dim rowTemp As DataRow
            rowTemp = DsmhcpTreatmentPlan1.Tables(0).NewRow()
            rowTemp.Item("lngPatientid") = lngpatientid
            DsmhcpTreatmentPlan1.Tables(0).Rows.Add(rowTemp)
0
