從點擊asp超鏈接列表視圖中檢索文本VB.net

Question

當用戶單擊超鏈接並將其傳遞到會話ID時，我遇到檢索文本時出現問題。當我嘗試調試時，它甚至不會停止在斷點處。在ListView中單擊是否無法傳回任何文本？樓下是我的代碼：

<asp:ListView ID="orderContent" runat="server"> 
    <ItemTemplate> 
    <asp:HyperLink ID="orderNumbers" runat="server" NavigationURL="/demo.aspx" click="onClick();"><%(Eval("Number"))%></asp:HyperLink> 
    </ItemTemplate> 
</asp:ListView> 

Public Sub onClick(ByVal sender As Object, ByVal e As ListViewItemEventArgs) 
Dim orderTextNumber As String = CType(Me.FindControl("orderNumbers"),HyperLink).Text() 
    Session.Add("Orders", orderTextNumber) 
End Sub 

Answer 1

使用一個LinkBut​​ton而不是超鏈接

<asp:ListView ID="orderContent" runat="server"> 
    <ItemTemplate> 
     <asp:LinkButton ID="orderNumbers" runat="server" NavigationURL="/demo.aspx" OnClick="ordersNumbers_Click"><%(Eval("Number"))%</asp:LinkButton> 
    </ItemTemplate> 
</asp:ListView> 

獲取LinkBut​​ton的文本，並將其添加到會話

Public Sub orderNumbers_Click(ByVal sender As Object, ByVal e As ListViewItemEventArgs) 
    Dim orderTextNumber As String = CType(Me.FindControl("orderNumbers"),LinkButton).Text() 
    Session.Add("Orders", orderTextNumber) 
End Sub
