C# ASP.NET MVC 4上模式弹出窗口中的必需属性无效

我的弹出窗口出现，当文本框为空时，必须在我的弹出窗口中显示所需消息，但它不会出现。我使用数据注释

这是我的视图代码：

@model BLL.Boards
@{

AjaxOptions ajaxOptions = new AjaxOptions
{
    UpdateTargetId = "Board_list",
    LoadingElementId = "loading",
    LoadingElementDuration = 1000,
    OnComplete = "closeDialog('Board')"
};
 }
<fieldset>
<legend>Boards List</legend>
@using (Ajax.BeginForm("Edit", ajaxOptions))
{
      @Html.ValidationSummary(true)
      @Html.HiddenFor(model => model.BoardID)
    <table>
       <tr>
            <td>@Html.LabelFor(model => model.BoardName)</td>
            <td>@Html.EditorFor(model => model.BoardName)</td>
            <td>@Html.ValidationMessageFor(model => model.BoardName)</td>

        </tr>
       <tr>
            <td>@Html.LabelFor(model => model.BoardDescription)</td>
            <td>@Html.EditorFor(model => model.BoardDescription)</td>
            <td>@Html.ValidationMessageFor(model => model.BoardDescription)</td>
        </tr>


    </table>
    <input type="submit" class="btn btn-primary" value="Save" /> 
    <input type="button" class="btn btn-primary" value="Cancel"/>
   }
   </fieldset>

您能否显示说明这些字段应为必填字段的代码？也许UI中的文本框中会出现错误，我的意思是这里的编辑器。您是否在视图中或何处包含了jquery验证库？并给出示例
