Kendo Combobox 未触发所需的验证消息答案

【问题标题】：Kendo Combobox Not Triggering Required Validation MessageKendo Combobox 未触发所需的验证消息
【发布时间】：2017-05-19 14:10:36
【问题描述】：

我已经为我的 MVC 视图实现了必需的验证。文本控件显示验证消息，但剑道组合框不显示。我正在做一个ajax回发。

comboxbox 不显示消息的任何原因？工作类型组合是强制性的，但它不显示验证消息。

【解决方案1】：

尝试添加这个：

<script>
    $(function () {
        $("form").kendoValidator();
    });
</script>

和/或：

<script>
    $.validator.setDefaults({
        ignore: ""
    });
</script>

【讨论】：

知道如何为 Kendo().RadioButton 实现相同的功能吗？

【解决方案2】：

您可以设置验证规则来强制选择一个项目：

$("form").kendoValidator({
        rules: {
            invalidSelection: function (input) {
                if (input.is("[name=COMBO_NAME]")) {
                    if (input.val() != "" && $("#TCOMBO_NAME").data("kendoComboBox").selectedIndex == -1) {
                        return false;
                    }
                }
                return true;
            }
        }
    });

这样，它遍历表单的所有字段，能够为每个字段建立规则。问候。
