如何从VB.net中的List视图中获取Current值

Question

我是vb.net的新手

我在来自DB的listview中显示数据。我希望获得用户选择的一些细节。 这是home.aspx中的My Listview

<asp:SqlDataSource ID="datasource1" runat="server" 
                   ConnectionString="<%$ ConnectionStrings:test %>" 
                   ></asp:SqlDataSource>

    <asp:ListView ID="ListView1" runat="server" OnItemCommand="data_OnItemCommand" DataKeyNames= "dataSortID" allowsorting="true" DataSourceID="datasource1"> 
  <LayoutTemplate>
        <asp:DataPager ID="dpListView" runat="server" PageSize="4" >
        <Fields> <asp:NextPreviousPagerField ButtonType="Link" 
              ShowFirstPageButton="true"
              ShowPreviousPageButton="true"
              ShowLastPageButton="false" 
              ShowNextPageButton ="false"/>
           <asp:NumericPagerField ButtonType="Link" NextPageText="more.." />
           <asp:NextPreviousPagerField ButtonType="Link" 
              ShowFirstPageButton="false"
              ShowPreviousPageButton="false"
              ShowLastPageButton="true" 
              ShowNextPageButton ="true"/>
            </Fields>
    </asp:DataPager>
    <br />
    <br />    
            <div id="ItemPlaceHolderContainer" runat="server" >
                <span id="ItemPlaceHolder" runat="server"></span>
            </div>
  </LayoutTemplate>  
  <ItemTemplate > 
    <div >
<%# Eval("Username")%>

                <asp:LinkButton runat="server" ID="UserAccept" Text="Accept" CommandName="select" CommandArgument="<%# Eval("dataSortID")%>" />
                <asp:LinkButton runat="server" ID="UserDecline" Text="Decline" CommandName="Decline" CommandArgument="<%# Eval("dataSortID")%>"/>

    </div>
  </ItemTemplate> 
</asp:ListView>

这是我的home.aspx.vb

Protected Sub data_OnItemCommand(ByVal sender As Object, _
                                                    ByVal e As ListViewCommandEventArgs)
        If String.Equals(e.CommandName, "select") Then

            TextBox1.Text = "It worked perfectly"

            Dim dataItem As ListViewDataItem = e.Item

            var routeLabel = (Label)item1.FindControl("routenameLabel");
             lblResponseRoute.Text = routeLabel.ID.ToString();
**TextBox2.Text = [sortID of the selected item]**
        Else
            TextBox1.Text = "Not worked"
        End If
    End Sub

所以我无法获得相应所选项目的sortid。

任何人都可以帮我解决这个问题。
