我试图在programm中动态绑定radiobutton列表。但是我愿意   不知道如何插入价值。

Aspx网页代码

<asp:Table ID="tblSponser" runat="server"  cellpadding="0" cellspacing="10" Visible="false"></asp:Table>

on dropdownlist selectedindex事件我在Code中绑定单选按钮后面

  Protected Sub ddlVotes_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles ddlVotes.SelectedIndexChanged

    For SponserId = 0 To sponserDtst.Tables(0).Rows.Count - 1
                    Dim tr As New TableRow
                    Dim c1 As New TableCell
                    Dim c2 As New TableCell

    Dim rbtyes As New RadioButtonList

                    rbtyes.ID = "rbtypes" & SponserId
                    rbtyes.ClientIDMode = UI.ClientIDMode.Static
                    rbtyes.Items.Add(New ListItem("Yes"))
                    rbtyes.Items.Add(New ListItem("No"))
                    rbtyes.RepeatDirection = RepeatDirection.Horizontal
                    c2.Controls.Add(rbtyes)
    c2.Controls.Add(rbtyes)
                    tr.Controls.Add(c1)
                    tr.Controls.Add(c2)
                    tblSponser.Controls.Add(tr)

下面的代码不起作用。如何获得radiobuttonlist和按钮点击事件存储在数据库中。

Protected Sub btnSubmitVote_Click(sender As Object, e As System.EventArgs) Handles btnSubmitVote.Click

    Dim i As Integer
            Dim x As Integer = 5
            For i = 0 To x - 1
                Dim str As String = "rbtypes" & i
                Dim rb As RadioButtonList = CType(tblSponser.FindControl(str), RadioButtonList)
                Dim ix As String = rb.SelectedValue
            Next
