我Ext.NET GridPanel用来在我的系统中显示项目任务列表，每个任务都有其进度状态，如Finished、Running、Not started等。

这是我的网格面板的一部分：

这些进度状态是我数据库中另一个表的记录，就像这样： 在此处输入图像描述

它是相关的SprintStatus->SprintStatusID我SprintStatusName在我的gridPanel.

我想做的是通过 StatusName 对它进行本地过滤，但我能做到这一点的唯一方法是ext:ListFilter使用它的 ID（1、2、3、4）设置我的选项，这不好，因为我不想要显示 ID

这是过滤器

在此处输入图像描述

如何让它显示 StatusName 而不是 StatusID？

这是一种使用 Store 为 ListFilter 提供选项的方法。

但是......这个样本有问题。过滤器实际上并未正确应用。我必须做更多的研究。

一旦我弄清楚到底出了什么问题，我会回来编辑这篇文章。

我还将尝试确定您是否可以仅使用 .Options 属性设置名称：值对。

编辑：示例已更新。

例子

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
   protected void Page_Load(object sender, EventArgs e)
   {
       if (!X.IsAjaxRequest)
       {
           var companies = new[] { 
               new { ID = 1, Name = "Company A", Size = 3 },
               new { ID = 2, Name = "Company B", Size = 1 },
               new { ID = 3, Name = "Company C", Size = 5 },
               new { ID = 4, Name = "Company D", Size = 3 },
               new { ID = 5, Name = "Company E", Size = 4 },
           };

           this.Store1.DataSource = companies;
           this.Store1.DataBind();


           var sizes = new [] { 
               new { Name = "Extra Small", ID = 1  },
               new { Name = "Small",       ID = 2  },
               new { Name = "Medium",      ID = 3  },
               new { Name = "Large",       ID = 4  },
               new { Name = "Extra Large", ID = 5  }
           };

           this.Store2.DataSource = sizes;
           this.Store2.DataBind();
       }
   }
