如何使用eval值更改html元素顯示？

Question

<td scope="col" style='display:<%#Eval("RETURNSTATUS")=='0'? "none" : "inline"%>'> 
    <asp:Button ID="Button1" runat="server" Text="İade Et" /> 
</td> 

我寫了這段代碼，但沒有工作。你能幫忙嗎？

Answer 1

感謝您的回覆，但像this.I創建hiddenfield和設定值由#eval

<td scope="col" > 

<asp:Button ID="btnReturn" runat="server" CommandArgument='<%#Eval("InventoryId")%>'  Text="İade Et" OnClientClick="return confirmReturnInventory()" /> 
    <asp:HiddenField ID="hdnStatus" runat="server" Value='<%# Eval("Status") %>' /> 
</td> 

在C＃背後不幹活解決的問題，我寫了中繼的方法PreRender事件

protected void rptInventoryList_PreRender(object sender, EventArgs e) 
    { 
     foreach (RepeaterItem ri in rptInventoryList.Items) 
     { 
      HiddenField hdnStatus = (HiddenField)ri.FindControl("hdnStatus"); 
      Button btnReturn = (Button)ri.FindControl("btnReturn"); 
      btnReturn.Visible = hdnStatus.Value == "0"; 

     } 
    }

你可以試試這段代碼嗎？

<td scope="col" style='<%#Eval("RETURNSTATUS")=="0"? "display:none" : "display:inline"%>'> 
<asp:Button ID="Button1" runat="server" Text="İade Et" /> 
</td>
