my code behind:
Private Sub FirstGridViewRow()
Dim dt As New DataTable()
Dim dr As DataRow = Nothing
dt.Columns.Add(New DataColumn("Bil", GetType(String)))
dt.Columns.Add(New DataColumn("Wheel Record No", GetType(String)))
dt.Columns.Add(New DataColumn("SMH", GetType(String)))
dt.Columns.Add(New DataColumn("Tindakan", GetType(String)))
dt.Columns.Add(New DataColumn("Jenis Tayar", GetType(String)))
'dt.Columns.Add(New DataColumn("Kuantiti", GetType(String)))
dr = dt.NewRow()
'dr("RowNumber") = i + 1
dr("Wheel Record No") = String.Empty
dr("SMH") = String.Empty
dr("Tindakan") = String.Empty
dr("Jenis Tayar") = String.Empty
'dr("Kuantiti") = String.Empty
dt.Rows.Add(dr)
grvDO.DataSource = dt
grvDO.DataBind()
End Sub
'A method that Inserts the records to the database
Private Sub InsertRecords(ByVal sc As StringCollection)

Dim sb As New StringBuilder(String.Empty)
Dim splitItems As String() = Nothing
For Each item As String In sc
Const sqlStatement As String = "Insert into delivery_order (tarikh,contractno,tindakan,jenisroda,wheelno,smhref,dono,authorizedby,kuantiti,status) values "
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray())
sb.AppendFormat("{0}('{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}'); ", sqlStatement, splitItems(0), splitItems(1), splitItems(2), splitItems(3), splitItems(4), splitItems(5), splitItems(6), splitItems(7), splitItems(8), splitItems(9))
