Y've already helped me a lot. But I have another trouble. I have an XtraGrid with data. Two columns configured to show checked list box for filtering. For example one column for States and other for Cities. This listboxes contains column data, so user can check multiple values and grid will ilter up its view. But when you choose filter in first column (for example one State) and then op
你已经帮了我很多了。 但我有另一个麻烦。 我有一个带数据的XtraGrid。 两列配置为显示选中列表框进行过滤。 例如，一个国家列和一个城市列。 这个列表框包含列数据，所以用户可以检查多个值，网格将过滤它的视图。 但是，当您在第一列（例如一个州）中选择过滤器，然后打开第二列过滤器时，其列表框将包含来自网格的所有数据（包含所有可用的城市，但不包括来自过滤状态的城市），但不包含当前过滤视图。 是否有任何方
I have a list of buttons around 100. I'm setting visibile to false in aspx page and then when needed I'm trying to set visibility to true from code behind. I cannot do Button1.Visible = true; (where Button1 is the Id of the button because there are about 100 buttons) Is there any other way to set visibility to true from code behind? I'm creating a function which will accept the
我有一个100左右的按钮列表。我在aspx页面设置visibile为false，然后在需要的时候，我试图从后面的代码中将可见性设置为true。 我不能做Button1.Visible = true; （其中Button1是按钮的ID，因为大约有100个按钮） 有没有其他方法可以将背后的代码设置为true？ 我正在创建一个函数，它将接受按钮的ID，然后我想将可见性设置为true。 您可以使用“Display：none”而不是像下面的代码那样的“Visible = false”。 Button1.Style

最初一个表在ASP.NET页面中是不可见的。 在按钮点击事件，它应该去后面的代码，并从那里我需要在JavaScript中调用一个函数。 在那个javascript函数中，我应该让表格可见。 这可能吗？？ 有人请帮助我 尝试这个： Page.ClientScript.RegisterStartupScript(GetType(), "MyKey", "Myfunction();", true); 尝试下面的代码 ScriptManager.RegisterStartupScript(this, this.GetType(), "isActive", "alert('hello');", true);
From my understanding one of the main things that async and await do is to make code easy to write and read - but is using them equal to spawning background threads to perform long duration logic? I'm currently trying out the most basic example. I've added some comments inline. Can you clarify it for me? // I don't understand why this method must be marked as `async`. private async v
根据我的理解， async和await的主要事情之一是使代码易于编写和读取 - 但是使用它们等同于产生后台线程来执行长期逻辑？ 我目前正在尝试最基本的例子。 我在内部添加了一些评论。 你能为我澄清一下吗？ // I don't understand why this method must be marked as `async`. private async void button1_Click(object sender, EventArgs e) { Task<int> access = DoSomethingAsync(); // task independent stuff

Can optimizing compiler delete infinite loops, which does not changes any data, like while(1) /* noop */; From analyzing a data flow graph compiler can derive, that such loop is "dead code" without any side effects. Is deleting of infinite loops prohibited by C90/C99 standards? Does C90 or C99 standards permit compiler to deleting such loops? Upd: "Microsoft C version 6.
可以优化编译器删除无限循环，它不会改变任何数据，比如 while(1) /* noop */; 从分析编译器可以派生的数据流图中可以看出，这样的循环是“死代码”，没有任何副作用。 是否删除了C90 / C99标准禁止的无限循环？ C90或C99标准是否允许编译器删除这些循环？ 更新：“微软C版本6.0基本上做了这种优化。”，请参阅由caf链接。 label: goto label; return 0; 将被转化为 return 0; C11在C11标准部分草案中澄清了这个问题
I have a gave, which, when it's finished, has a table of players and their scores. On the other hand i have a virtual pot of money that i want to distribute among these winners. I'm looking for a SQL query or piece of C# code to do so. The descending sorted table looks like this: UserId | Name | Score | Position | % of winnings | abs. winnings $ 00579 | John | 754 | 1 | ?
我有一个球员，当球员完成时，他有一张球员表和他们的分数表。 另一方面，我有一笔虚拟的钱，我想在这些赢家中分配。 我正在寻找一个SQL查询或一块C＃代码来做到这一点。 降序排序表如下所示： UserId | Name | Score | Position | % of winnings | abs. winnings $ 00579 | John | 754 | 1 | ? | 500 $ 98983 | Sam | 733 | 2 | ? | ? 29837 | Rick | 654 | 3
I have an error validation issue with an int. I have validation for a customer name: if (String.IsNullOrEmpty(CustomerName)) yield return new RuleViolation("Customer Name Required", "CustomerName"); now if I want to add validation for a city, in this case I have a CityID that gets saved as type int, so I can't write my if statement the same way...because there's no int.IsN
我有一个int错误验证问题。 我对客户名称进行了验证： if (String.IsNullOrEmpty(CustomerName)) yield return new RuleViolation("Customer Name Required", "CustomerName"); 现在如果我想为城市添加验证，在这种情况下，我有一个保存为int类型的CityID，所以我不能用同样的方法编写if语句...因为没有int.IsNullOrEmpty方法。 假设用户没有选择城市的下拉菜单 - 基本上没有价值的节省。 为int编写验证语句
