内联代码不触发方法 [英] inline code doesn't fire method

问题描述

我在类文件夹中有一个类名称PermissionControl.
当我在内联代码中使用它时不会触发

I have a class Name PermissionControl in class folder.
when I use it in in inline code it doesn''t fire

public class PermissionControl
    {
private static readonly HttpSessionState Session = HttpContext.Current.Session;
private static readonly HttpApplicationState Application = HttpContext.Current.Application;
        public static bool CheckPermission(string PermissionConstantName)
        {
           //my code
        }
}

我在这里称呼它:

and I call it here:

<asp:LinkButton ID="btn1" Visible='<%# CustomPermission.Class.PermissionControl.CheckPermission("Install") %>' runat="server">install module</asp:LinkButton>

为什么方法不触发?
我什至设置了一个断点，但甚至没有调用我的方法！

why method doesn''t fire?
I even set a break point but don''t even call my method!

推荐答案

Try:
<%= %>-嵌入式代码块而不是<%# %>，因为这是一个数据绑定表达式.

请参考: ASP.NET中的服务器端分隔符 [ ^ ]

Try:
<%= %> - Embedded Code Blocks instead of <%# %> as that is a Data-binding Expression.

Refer: Server side Delimiters in ASP.NET[^]
