在列表視圖中通過命令參數傳遞Eval

Question

我有一個鏈接按鈕，我試圖將參數傳入OnClick事件處理程序。爲此，我正在使用CommandArgument字段。

我有一個ListView，所以我retireving使用Eval數據中此鏈接按鈕，所以我想是值傳遞到CommandArgument這樣：

<asp:LinkButton id="BTN_ApproveTicket" runat="server" CommandArgument="<%#Eval("TicketNum").ToString()%>" OnClick="BTN_ApproveTicket_Click"> 
</asp:LinkButton> 

我做這個確切的認爲一些表元素在我的頁面中，但是這個不起作用。

我得到的錯誤是它採用<%#Eval("TicketNum").ToString()作爲文字，所以我得到一個服務器標籤沒有很好的格式化錯誤。任何想法如何解決這個將不勝感激。

這是AlternatingItemTemplate是有問題：

<AlternatingItemTemplate> 
<td style="<%#setTicketClass(Eval("TicketNum").ToString(), Eval("UnitID").ToString(), Eval("TicketDate").ToString())%>" > 
<asp:LinkButton id="BTN_ApproveTicket" runat="server" CommandArgument='<%#Eval("TicketNum").ToString()%>' OnClick="BTN_ApproveTicket_Click"> 
     <i class="fa fa-check-square-o" style="<%#setCheckBoxClass(Eval("Approved").ToString())%>" ></i> 
     </asp:LinkButton>

這可能與報價的事 - 你到處都使用了雙引號，這可能會混淆解析器。嘗試用單引號替換外部引號：

CommandArgument='<%#Eval("TicketNum").ToString()%>'
