Thanks everyone for the reply's but I ended up doing this:
Private Sub searchPartsDataGridView_CellContentClicked(sender As Object, e As DataGridViewCellEventArgs) Handles searchPartsDataGridView.CellContentDoubleClick
Dim colName As String = searchPartsDataGridView.Columns(e.ColumnIndex).Name()
Dim rowIndex = searchPartsDataGridView.CurrentRow.Index
If colName = "ITEMNO" Then
formPartsRequest.partsRequestItemsDataGridView.Rows.Add(searchPartsDataGridView.Rows(rowIndex).Cells("ITEMNO").Value, searchPartsDataGridView.Rows(rowIndex).Cells("DESC").Value)
End If
End Sub
Not sure if this is the best way to do it or if its good coding practice but It seem's to work fine and it suit's my purposes. Thanks
