[C＃] WPF - 如何填充数据网格并以编程方式编辑项目。 [英] [C#] WPF - How to populate a datagrid and edit the items programmatically.

问题描述

嘿那里。我一直在努力开发几天。陷入困境，因为我总是因为日程繁忙而感到疲惫，而且没有集中注意力，所以思考一直很困难。但我有一个数据网格，我想以编程方式填充。该程序登录到服务器，并获取游戏服务器列表。我想用ping和map等信息填充我的数据网格，让我了解代码是如何设置的。我不知道如何添加一行所需的所有信息。由于缺乏休息，我的措辞也非常糟糕。哈哈。这里有一些例子。



这是一些Launcher.cs类

  private   void  ServerListenerName（ int  id， string  name）
 {
 Console.WriteLine（ 服务器{0}名称= {1}，id，name）; 
 Application.Current.Dispatcher.Invoke（（Action）（（）= >  
 {
 w.addName（id， name）; 
}））; 
 
} 
 
  private   void  ServerListenerAttr（< span class =code-keyword> int  id， string  name， string   value ）
 {
 Console.WriteLine（ 服务器{0} attr {1} = {2}，id，name， value ）; 
} 
 
  private   void  ServerListenerCap（ int  id， int  cap0， int  cap1）
 {
 Console.WriteLine（  server {0} cap0 = {1} cap1 = {2}，id，cap0，cap1）; 
} 
 
  private   void  ServerListenerState（ int  id， int  state）
 {
 Console.WriteLine（  server {0} state = {1}，id，state）; 
 
} 
 
  private   void  ServerListenerPlayers（< span class =code-keyword> int  id， int  players）
 {
 Console.WriteLine（  server {0} players = {1}，id，players）; 
} 
 
  private   void  ServerListenerAddr（ int  id， string  ip， int  port）
 {
 Console.WriteLine（  server {0} ip = {1} port = {2}，id，ip，port）; 
} 
 

如你所见，它分为不同的事件。我希望将每个事件的特定部分放到一个字符串中传递给窗口，窗口是w。如果你看，他们都有（int id），那么有没有办法根据他们的id为我的datagrid的项添加信息？这是w.addName（id，name）的代码;

 public void addName（int sID，string sName）
 {
 servl.Items。添加（新zList {zID = sID，zName = sName，zMap =map，zPlayers =10/64，zGamemode =tdm，zPing = 74}）; 
} 
 
公共类zList 
 {
 public int zID {get;组; } 
 public string zName {get;组; } 
 public string zMap {get;组; } 
 public string zPlayers {get;组; } 
 public string zGamemode {get;组; } 
 public int zPing {get;组; } 
} 

不要介意 servl.Items.Add（new zList {zID =下的临时字符串/整数sID，zName = sName，zMap =map，zPlayers =10/64，zGamemode =tdm，zPing = 74}）; ，因为它们仅用于一般列表填充。



数据网格的XAML

 <   DataGrid     x：名称  =  servl    Horizo​​ntalAlignment   = 左   保证金  =  175,10， 0,0    VerticalAlignment   =  Top   高度  =  676   宽度  =  1054    FontFamily   =  Geared Slab >  
 <   DataGrid.Columns  >  
 <   DataGridTextColumn     Binding   =  {Bin ding Path = zID}    ClipboardContentBinding   =   {x：Null}   前景  = ＃FFDADADA    FontWeight   = 粗体    FontFamily   =  Geared Slab   标题  =   ID    SortDirection   = 升序    CanUserResize   =  False   宽度  =  40  /  >  
 <   DataGridTextColumn    绑定  =  {Binding Path = zName}     ClipboardContentBinding   =  {x：Null}   前景 < span class =code-keyword> =  #FF DADADA   标题  = 名称    CanUserResize   =  False    FontFamily   =  Geared Slab   宽度  =  250  /  >  
 <   DataGridTextColumn    绑定  =  {Binding Path = zMap}     ClipboardContentBinding   =  {x：Null}   前景 < span class =code-keyword> = ＃FFDADADA   标题  = 地图    CanUserResize   =  False    宽度  = < span class =code-keyword> 130  /  >  
 <   DataGridTextColumn     Binding   =  {x：Null}    ClipboardContentBinding   =  {x：Null}   前景  = ＃FFDADADA   标题  = 玩家    CanUserResize   =  False   宽度  =  85  /  >  
 <   DataGridTextColumn     Binding   = < span class =code-keyword> {x：Null}    ClipboardContentBinding   =  {x：Null}   前景  = ＃FFDADADA   标题  =  Gamemode    CanUserResize   =  False   宽度  =  135   /  >  
 < ;   DataGridTextColumn    绑定 < span class =code-keyword> =  {x：Null}   < span class =code-attribute> ClipboardContentBinding   =  {x：Null}   前景  = ＃FFDADADA   标题  =  Ping  /  >  
 <   /DataGrid.Columns  >  
 <   / DataGrid  >  

所以对于TL; DR [太长了，没读过]，我想将服务器添加到我的数据网格中，但考虑到Launcher.cs代码的设置，我不知道如何。感谢您的时间。

解决方案

您需要将ItemsSource绑定到zList

Hey there. I've been struggling with developing for a few days now. Caught in a loop, because I'm always tired due to a busy schedule, and not concentrated, so thinking has been difficult. But I have a datagrid I want to programmatically populate. The program signs into a server, and gets a list of game servers. I want to populate my datagrid with information such as ping, and maps, etc, and what gets me is how the code is set up. I wouldn't know how to add all of the information needed for a row. My wording is also pretty terrible, due to lack of rest. Haha. Anywho here's some examples.

This is some of the Launcher.cs Class

        private void ServerListenerName(int id, string name)
{
    Console.WriteLine("server {0} name = {1}", id, name);
                Application.Current.Dispatcher.Invoke((Action)(() =>
                {
                  w.addName(id, name);
                }));

}

private void ServerListenerAttr(int id, string name, string value)
{
    Console.WriteLine("server {0} attr {1} = {2}", id, name, value);
}

private void ServerListenerCap(int id, int cap0, int cap1)
{
    Console.WriteLine("server {0} cap0 = {1} cap1 = {2}", id, cap0, cap1);
}

private void ServerListenerState(int id, int state)
{
    Console.WriteLine("server {0} state = {1}", id, state);

}

private void ServerListenerPlayers(int id, int players)
{
    Console.WriteLine("server {0} players = {1}", id, players);
}

private void ServerListenerAddr(int id, string ip, int port)
{
    Console.WriteLine("server {0} ip = {1} port = {2}", id, ip, port);
}

As you can see, it's broken up into different events. I was hoping to get specific parts of each event into a single string to pass to the window, window being the "w". If you look, all of them have the (int id), so would there be a way to add information to my datagrid's items based on their id? Here's the code for w.addName(id, name);

public void addName(int sID, string sName)
        {
            servl.Items.Add(new zList { zID = sID, zName = sName, zMap = "map", zPlayers = "10/64", zGamemode = "tdm", zPing = 74});
        }

        public class zList
        {
            public int zID { get; set; }
            public string zName { get; set; }
            public string zMap { get; set; }
            public string zPlayers { get; set; }
            public string zGamemode { get; set; }
            public int zPing { get; set; }
        }

Don't mind the temporary strings/integers under the "servl.Items.Add(new zList { zID = sID, zName = sName, zMap = "map", zPlayers = "10/64", zGamemode = "tdm", zPing = 74});", as they are just for general list population.

XAML for the Datagrid

<DataGrid x:Name="servl" HorizontalAlignment="Left" Margin="175,10,0,0" VerticalAlignment="Top" Height="676" Width="1054" FontFamily="Geared Slab">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Path=zID}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" FontWeight="Bold" FontFamily="Geared Slab" Header="ID" SortDirection="Ascending" CanUserResize="False" Width="40"/>
                <DataGridTextColumn Binding="{Binding Path=zName}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" Header="Name" CanUserResize="False" FontFamily="Geared Slab" Width="250"/>
                <DataGridTextColumn Binding="{Binding Path=zMap}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" Header="Map" CanUserResize="False" Width="130"/>
                <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" Header="Players" CanUserResize="False" Width="85"/>
                <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" Header="Gamemode" CanUserResize="False" Width="135"/>
                <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Foreground="#FFDADADA" Header="Ping"/>
            </DataGrid.Columns>
        </DataGrid>

So for a TL;DR [Too long, didn't read], I want to add servers to my datagrid, but considering the set up of Launcher.cs's code, I wouldn't know how. Thanks for your time.

解决方案

You need to bind the ItemsSource to the zList
