Dynamically adding rows to table web server control

    I am trying to programmatically add rows of data to a table web control
    in VS2005. I am getting the data from 2 drop-down controls and 2
    text-boxes. The code below is executed when I click on the "add"
    button. The code is pretty much lifted from an example on MSDN.


    The first time I try to add a row, it works fine. But when I try to add
    another row, it simply overwrites the first. I need to add new row
    every time the user clicks the 'add' button.


    Protected Sub btnProdAdd_Click(ByVal sender As Object, ByVal e As
    System.EventArgs) Handles btnProdAdd.Click

    Dim tr As New TableRow()

    Dim cellGrade As New TableCell()
    cellGrade.Text = cboGrade.SelectedValue.ToString

    Dim cellStrips As New TableCell()
    cellStrips.Text = cboStrips.SelectedValue.ToString

    Dim cellYards As New TableCell()
    cellYards.Text = txtYards.Text.ToString

    Dim cellScrap As New TableCell()
    cellScrap.Text = txtScrap.Text.ToString


    End Sub

    your code needs to remember the rows it added on the last click, and
    re-add them on the postback (say in oninit).

    If I am understanding you correctly, you are saying that every time the
    user triggers the code to add a new record to the table control, the
    code has to re-add all of the existing records already in the table in
    addition to the new one?

    And this would be because of the statelessness of web apps?
