我试图让排序适用于DataGridView.当我单击列标题但是它不起作用时,排序应该是自动的.我究竟做错了什么？

private void LoadDummyData()
{
    List<AddressBookDummy> list = new List<AddressBookDummy>();
    list.Add(new AddressBookDummy { Name = "Newman, Alfred", Type = "CAR" });
    list.Add(new AddressBookDummy { Name = "Skywalker, Luke", Type = "SUP" });
    list.Add(new AddressBookDummy { Name = "Skywalker, Leia", Type = "BEN" });

    addressBookGrid.DataSource = list;
}

private void InitializeGrid()
{
    addressBookGrid.RowHeadersVisible = false;
    addressBookGrid.ScrollBars = ScrollBars.Vertical;
    addressBookGrid.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    addressBookGrid.Columns[0].SortMode = DataGridViewColumnSortMode.Automatic;
    addressBookGrid.Columns[1].SortMode = DataGridViewColumnSortMode.Automatic;
}

我在iPhone 7上找到了使用Google的用户代理字符串:

Mozilla/5.0 (iPhone; CPU iPhone OS 10_0 like Mac OS X) AppleWebKit/602.1.38 (KHTML, like Gecko) Version/10.0 Mobile/14A5297c Safari/602.1

iPhone 7 PLUS的用户代理字符串是什么？有什么区别吗？

我有一个修改一些文件的进程,我想通过命令行tortoise SVN提交它们,而不必点击确定.对话框出现,我的脚本被迫等到我点击确定.以下是我使用的参数:

TortoiseProc.exe /command:commit /path:"c:\svn\MyProject" /notempfile /logmsg:"Files Modified 2010-02-12" /closeonend:3

如果存在验证错误,我在必需的字段验证器控件上使用什么属性来使文本框变为红色？

这是我的代码:

<asp:Label ID="lblFirstName" runat="server" AssociatedControlID="txtFirstName" Text="First Name:" CssClass="reg-labels" />
<br />
<asp:TextBox ID="txtFirstName" runat="server" CausesValidation="true" MaxLength="60" CssClass="standard_width"/>
<asp:RequiredFieldValidator ControlToValidate="txtFirstName" runat="server" ID="valFirstName" ValidationGroup="grpRegistration" ErrorMessage="First Name is required." Text="*" />

我正在使用NpgSQL与PostgreSQL和ADO.NET.原谅这个问题的简单性,因为我本周刚刚开始使用PostgreSQL和NpgSQL.

这样的事情很好:

[Test]
public void InsertNoParameters()
{
    NpgsqlConnection conn = new NpgsqlConnection("Host=localhost; Database=postgres; User ID=postgres; Password=password");
    conn.Open();

    IDbCommand command = conn.CreateCommand();
    string sql = "INSERT INTO Customers (FirstName,LastName) VALUES ('Test','Tube')";
    command.CommandText = sql;
    command.ExecuteNonQuery();
    conn.Close();
}

当我输入参数时,我收到错误消息:Npgsql.NpgsqlException:错误:42703:列"_firstname"不存在

[Test]
public void InsertWithParameters()
{
NpgsqlConnection conn = new NpgsqlConnection("Host=localhost; Database=postgres; User ID=postgres; Password=password");
conn.Open();

IDbCommand command = conn.CreateCommand();
string sql = "INSERT INTO Customers (FirstName,LastName) VALUES (_FirstName,_LastName)";
command.CommandText = sql;

var parameter = command.CreateParameter();
parameter.ParameterName = "_FirstName";
parameter.Value = "Test";
command.Parameters.Add(parameter);

I am getting a post from an external vendor. I am not exactly sure what variables they are sending. How do I print out all the Request variables that they are sending in the post? there is no Request.Count or Request.Length so that I could loop and find everything.

Thanks in advance for your help.

我需要在Oracle中存储CRC签名的Int32值.我应该使用什么精度？

在Unix中,如何使用JSCH设置目录权限？我想做drwxrwxrwx.Filezilla说这个整数是775但是JSCH没有正确设置权限.在JSCH设置权限之后,Filezilla说它是407.

Json.NET中是否有一种自动方式，可以将JSON属性从小写的下划线自动映射到无大小写的下划线。我知道您可以向每个属性添加json属性，但这是唯一的方法吗？

我的JSON是这样的：

{
    "first_name": "Roger",
    "last_name": "The Shrubber"
}

这是课程：

public class Customer
{
    public FirstName { get; set; }
    public LastName { get; set; }
}

我想将日期列格式化为 Angular 2 NGX 数据表中的短日期。

这是 HTML：

<ngx-datatable
  [rows]="toDos"
  [columns]="columns">
</ngx-datatable>

这是组件 TypeScript

import { Component, OnInit } from '@angular/core';
import { IToDo } from '../shared/todo';
import { ToDoService } from '../shared/todo.service';

@Component({
  selector: 'app-todo-list',
  templateUrl: './todo-list.component.html',
  styleUrls: ['./todo-list.component.css']
})

export class TodoListComponent implements OnInit {

  toDos: IToDo[];
  columns = [
    { prop: 'toDoId' },
    { name: 'To Do', prop: 'name' },
    { prop: 'priority' },
    { prop: 'dueDate'  },
    { prop: 'completed' }
  ];

  constructor(private _toDoService: ToDoService) {
  } …
