asp.net - 如何使用 eval 值更改 html 元素显示？

Question

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

我写了这段代码但不起作用。你能帮忙吗？

Answer 1

感谢您的回复，但它不起作用。我解决了这样的问题。我创建隐藏字段并通过#eval 设置值

<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#后面，我写了repeater的方法preRender event

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";

        }
    }

你能试试这个代码吗？

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