Telerik RadGrid更新命令未触发

标签： c# asp.net webforms telerik

所以，我有一个RadGrid的典型编辑安排正在运作......现在还没有。永远不要触发UpdateCommand事件，在那里设置一个断点并且没有到达它。让我发疯，因为它工作得很好，我无法想到我所做的任何会导致它的事情。当我单击编辑时，窗体打开就好了，取消按钮工作，但更新命令永远不会触发。 在网格中我有：

OnUpdateCommand="pendingVehiclesRadGrid_UpdateCommand" 

And in my code behind I have:

 protected void pendingVehiclesRadGrid_UpdateCommand(object source, GridCommandEventArgs e)
{
blah blah
}

看起来很简单，但正如我所说......没什么。如果有新眼睛的人可以提出建议，我将一如既往地深表感激。

编辑以添加XML：

我试图重建你的例子并且它有效：

ASPX：

    <FilterMenu EnableImageSprites="False" />

代码隐藏：

protected void pendingVehiclesRadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    this.pendingVehiclesRadGrid.DataSource = new List<object> {
        new {
            id = 1,
            charity = "charity1",
            vin = "vin1",
            year = 2015,
            make = "make1",
            model = "model1",
            date = DateTime.Now.AddYears(-1),
            bid = (decimal)12000.00,
            salePrice = (decimal)14469.95,
            note = "a new car",
            Status = "NOT SOLD"
        },
        new {
            id = 2,
            charity = "charity2",
            vin = "vin2",
            year = 1967,
            make = "make2",
            model = "model2",
            date = DateTime.Now,
            bid = (decimal)14000.00,
            salePrice = (decimal)19469.95,
            note = "an oldtimer",
            Status = "NOT SOLD"
        }
    };
}

protected void pendingVehiclesRadGrid_UpdateCommand(object sender, GridCommandEventArgs e)
{
    Console.WriteLine("This will be reached!"); // I've put the breakpoint here
}

protected void pendingVehiclesRadGrid_ItemCommand(object sender, GridCommandEventArgs e)
{

}

正如您所看到的，我删除了一些不必要的标记，但这不是问题的来源。我还必须删除RadComboBox中的EditItemTemplate，因为我无法使用LinqDataSource1。

但要明确：我不知道为什么它不适用于您，但我希望这可以帮助您跟踪问题。

尝试对RadComboBox发表评论。看看这是否是问题来源。如果没有，你可能会在你的代码中犯任何错误，也许在数据绑定本身。

如果无法跟踪问题，请尝试在自己的解决方案中隔离问题。使用硬编码数据（如我的例子）将其钉死。如果问题仍然存在，请发布测试解决方案中的所有代码或共享解决方案本身不带 Telerik组件（！）

@modiX好的...再次感谢你的帮助。我还没有弄明白这个问题，但是在对抗它两天之后，我意识到，在某一点上，这完成了所有工作，也许在我在表格上做的所有其他工作的某个地方，我打破了它并没有实现它直到为时已晚。因此，我开始逐个删除三个网格中的每个网格及其代码，并将它们粘贴到一个全新的页面中。并且...他们工作。

不知道什么“特征”导致他们打破，但我愿意称之为胜利并继续...更谨慎;）

再次感谢你的时间和善意的帮助！
