【问题描述】：
我有一个显示作业列表的 ListView 控件。我有一排 LinkButton 控件，单击时会按作业的各个字段对列表进行排序。
我在页面上还有一个 TextBox 控件和 LinkButton 控件。
我想在 TextBox 中输入一个关键字来过滤 ListView。单击 LinkButton 控件后，ListView 过滤器将仅显示关键字包含在我们排序依据的 4 种模式之一中的结果（日期、公司、标题、位置）。
这里没有包含其他代码和类，而且我是 C# 新手，所以如果我遗漏了需要的部分，请告诉我。
文本框：
<asp:TextBox ID="txtKeySearch" CssClass="form-control" runat="server" />
按钮：
<asp:LinkButton ID="lnkbtnKeySearch" runat="server" class="fancy" >
<span>Search <span class="ico-chevron-right"></span></span></asp:LinkButton>
