How to extract data from a TextBox to a GridView (multiple rows to be displayed in the GridView)?

I have used the following code to display data from Text Boxes and combo boxes to a Grid View without saving the data to the database. When I enter the data in the Text Boxes, and click on the Button, those values will be displayed in the Grid view. It is working as expected without any errors.
But I want to tweak the code a bit so that the Grid View should be able to add new data from the Text boxes by retaining the old data as it is in the Grid view (multiple rows should be displayed in the Grid view instead of single rows).

It is an desktop application, I'm using visual basics and visual studio 2012. My code so far:

VB

Public Sub DataTabel_TblDetali()

        Dim TblDetali As New DataTable()

        'Se kreira dataTabel so oderdeniKoloni
        TblDetali.Columns.Add("BrojBaranje", GetType(String))
        TblDetali.Columns.Add("RedBroj", GetType(Integer))
        TblDetali.Columns.Add("Apoen", GetType(Decimal))
        TblDetali.Columns.Add("Evidenciski_Broj", GetType(String))
        TblDetali.Columns.Add("InventarenBroj", GetType(String))
        TblDetali.Columns.Add("OznakaSerija", GetType(String))
        TblDetali.Columns.Add("VidSeriskiBroj", GetType(String))
        TblDetali.Columns.Add("GodinaIzdavanje", GetType(String))
        TblDetali.Columns.Add("BrojParcinja", GetType(Integer))
        TblDetali.Columns.Add("SeriskiBroj1", GetType(String))
        TblDetali.Columns.Add("SeriskiBroj2", GetType(String))
        TblDetali.Columns.Add("BrojIndikativ", GetType(String))
        TblDetali.Columns.Add("TipKlasa", GetType(String))
        TblDetali.Columns.Add("TipReprodukcija", GetType(String))
        TblDetali.Columns.Add("BrojNalog", GetType(String))



        Dim RedenBroj As Integer = 0
        TblDetali.Rows.Add(BrojBaranje, RedenBroj + 1, Apoen, EvidenciskiBroj, InventarenBroj, OznakaZaSerija, VidSeriskibroj, GodinaIzdavanje, BrojParcinja, SeriskiBroj1, SeriskiBroj2, BrojIndikativ, TipKlasa, TipReprodukcija, "")

        grdDetaliVnos.DataSource = TblDetali
        RedenBroj = RedenBroj + 1

Hey there,

You could save the DataTable in the Session after adding row to it.
This way when you want to add another row, just get the DataTable back from Session, add a row to the table, bind it to the GridView and save it back to the same Session

Here:
Use this statement:

VB

If Session("MyTable") IsNot Nothing Then
TblDetali = ctype(Session("MyTable"), DataTable)  End If

after:

VB

Dim TblDetali As New DataTable()

and
this line:

VB

Session("MyTable") = TblDetali

before this line:

VB

grdDetaliVnos.DataSource = TblDetali

Hope it helps.
