Question

I have a button click event that adds text to a table. However, when I submit the form the values entered into the table don’t appear in the postback… is this possible to do?

Here is my code:

    Protected Sub AddRowToInputTables(table As Table, value As String)
    If table IsNot Nothing Then
        Dim id As String = value.Trim()
        Dim prefix As String = ""
        If (table.ID = "cust_num") Then ' todo - abstract this out and use a parameter for the prefix instead
            prefix = "CN"
        Else
            prefix = "RN"
        End If
        If id <> String.Empty Then
            Dim tr = New TableRow()
            Dim td = New TableCell()
            Dim td2 = New TableCell()
            Dim btnDelete = New ImageButton()
            btnDelete.ID = "btn" & prefix & "_" & id & "_del"
            btnDelete.ImageUrl = "http://res.xxxxxxxx.net/images/delete.png" ' todo - put this in the web.config or settings file
            tr.ID = id
            td.Text = id
            td2.Controls.Add(btnDelete)
            tr.Cells.Add(td)
            tr.Cells.Add(td2)
            Dim rows = New List(Of TableRow)()
            For Each row In table.Rows
                rows.Add(row)
            Next
            rows.Add(tr)
            table.Rows.Clear()
            table.Rows.AddRange(rows.ToArray())
            cust_num_txt.Value = String.Empty
            res_num_txt.Value = String.Empty
        End If
    End If
End Sub

Trick is to populate the table in the Load event only… then everything started working normally.
