如果关闭了模态弹出窗口而没有取消在模态内的网格视图中的行编辑，则它不会再次打开

我有一个gridview就地编辑。这个gridview被放置在一个模态弹出扩展器中。一切都很好，但如果我编辑一行和输入不符合验证规则的数据 (RegularExpressionValidator)和然后关闭模态弹出，模态将不会再次打开。

我尝试过不同的事情，比如使用jquery来查找取消链接并触发其点击事件，但似乎没有什么工作。最后，我还尝试在javascript函数中取消编辑关闭模态，但问题仍然存在。

下面是我的代码的简化版本:

JS

<script src="script/jquery-1.10.2.min.js" type="text/javascript"></script>
    <script language="javascript" type="text/javascript">
        function CerrarPopup(strMpeCliente) {
            // Find the Generated Cancel Button for the Row in Edit Mode.
            var cancelButton = $('#<%= GridView2.ClientID %>')
                               .find('a')
                               .filter(function() { return $(this).text() === "Cancelar" });
            // If Cancel Button is found, then show message and click the Cancel Button.
            if (cancelButton != null && cancelButton.length > 0) {
                buttonClick(cancelButton[0]);
            }
            var modalPopupBehavior = $find(strMpeCliente);
            modalPopupBehavior.hide();
        }
        function buttonClick(button) {
            button.click();
        }    
    </script>
