我正在尝试使用ajax发送呼叫,但在Chrome中它出现上升错误,但在Firefox中没有错误.但它仍然无法调用该方法.我试图用萤火虫记录我的电话,但是萤火虫没有电话请求.所以这就是firefox中没有错误的原因.

Index.chshtml代码如下

function onLoad(e) {

    var grid = $(this).data("tGrid");
    //bind to the context menu of the Grid's header
    event.preventDefault();
    $(this).find(".t-grid-header").bind('contextmenu', function (e) {
        //wait for the menu to be generated
        setTimeout(function () {
            // bind to the checkboxes change event. The context menu has ID in the format "GridName" + "_contextmenu"
            $('#globalsearchgrid_contextMenu :checkbox').change(function () {
                debugger;
                var $checkbox = $(this);
                // the checked state will determine if the column has been shown or hidden
                var checked = $(this).is(":checked");
                // …

我试图在报告中显示记录.数据位于数据集中.但它并不适合他们.表单加载时,它会显示报表布局.但是,当我点击按钮时,它显示错误.下面是我的代码.

我正在尝试从服务器注销.但是它会返回"0"响应代码并带有此异常.我正在使用GET动词来做到这一点.

我正在尝试为 rdlc 报告创建一个 Sp。其中我使用了许多用户定义的函数进行计算。但是当我试图在 group by 子句中使用函数别名时，它给出了一个错误“消息 207，级别 16，状态 1，第 14 行无效的列名‘CommPaid’”下面是我的查询

我正在按照本教程使用Entity Framework创建Master-Details Windows Forms, 但db.Savechanges()如果我修改了某个列或添加了一个新行,那么它就无法正常工作.根据这个视频教程,它可以工作,但事实并非如此.
