怪异的报错：DotNetNuke.Services.Exceptions.ModuleLoadException:The Runat attribute must have the value Server

最近在做一个DotNetNuke的模块，在页面调试过程中发现了一个怪异的抛出异常 The Runat attribute must have the value Server。

仔细阅读报错详细信息其中主要的信息是：Runat的值必须为Server，百思不得其解，代码看了几遍无意中发现

 <asp:TextBox ID="txtSearchR" runat="server "  value="请输入职位或企业名" CssClass="txt"></asp:TextBox>

中的 runat="server " server后面多了一个空格，去掉空格后发现模块就运行正常。

问题不大，但如果不仔细查找不容易发现错误，故拿出来和大家分享一下！希望能帮您一下！
