Question

 Sub ddlID_SelectedIndexChanged(sender As Object, e As EventArgs)
    Try
        Dim strConnection As String = "Data Source=Name\MSSQLSERVER12;Initial Catalog=Test;Integrated Security=true"
        Dim cmdText As String = "SELECT [id], [name], [address],[email] FROM [tbl_StudentRecord] where id=@id"

        Dim data As New DataTable()
        Dim adapter As New SqlDataAdapter(cmdText, strConnection)
        adapter.SelectCommand.Parameters.AddWithValue("@id", ddlID.SelectedValue)
        adapter.Fill(data)
        rptbind.DataSource = data
        rptbind.DataBind()

    Catch ex As Exception

    End Try
End Sub

在这个＆＃34;数据＆＃34;会来，但不会被束缚在转发器......？如何将数据显示到转发器中？

 <table style="margin-left: auto; margin-right: auto;">
            <asp:DropDownList ID="ddlID" runat="server" AutoPostBack="true" AppendDataBoundItems="True" DataTextField="ID" DataValueField="ID"
                OnSelectedIndexChanged="ddlID_SelectedIndexChanged">
                <asp:ListItem Text="--Select--" Value="0"></asp:ListItem>
            </asp:DropDownList>
        </table>

        <asp:Repeater ID="rptbind" runat="server">
        </asp:Repeater>

下面显示的是将数据绑定到Repeater（设计模式）的示例：

<asp:Repeater ID="rptReferences" runat="server">
  <ItemTemplate>                    
    <asp:Label ID="lblRef" ForeColor="#0869BD" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "FieldName")%>' visible="true"></asp:Label>
  </ItemTemplate>
</asp:Repeater>

将转发器值绑定在外部下拉列表中
