问题描述
我在用组合框填充数据网格组合框列时遇到问题，数据网格列未显示任何数据。但是，首先。这是我的绑定类：
public class StartingEleven
{
public string name { get; set; }
public int shirt_number { get; set; }
public string position { get; set; }
public bool captain { get; set; }
}
public class DGObject
{
public string FifaID { get; set; }
public string Venue { get; set; }
public string Location { get; set; }
public DateTime Date { get; set; }
public int Goals { get; set; }
public int Penalties { get; set; }
public string AwayTeamCode { get; set; }
public int GuestGoals { get; set; }
public List<StartingEleven> HomeTeam11 { get; set; }
}
还有我的根对象：
public class RootObject
{
public string venue { get; set; }
public string location { get; set; }
public string status { get; set; }
public string time { get; set; }
public string fifa_id { get; set; }
public Weather weather { get; set; }
public string attendance { get; set; }
public List<string> officials { get; set; }
public string stage_name { get; set; }
public string home_team_country { get; set; }
public string away_team_country { get; set; }
public DateTime datetime { get; set; }
public string winner { get; set; }
public string winner_code { get; set; }
public HomeTeam home_team { get; set; }
public AwayTeam away_team { get; set; }
public List<HomeTeamEvent> home_team_events { get; set; }
public List<AwayTeamEvent> away_team_events { get; set; }
public HomeTeamStatistics home_team_statistics { get; set; }
public AwayTeamStatistics away_team_statistics { get; set; }
public DateTime last_event_update_at { get; set; }
public DateTime last_score_update_at { get; set; }
}
有句话说：一张图片值一千字...所以，更准确地说，首先，这是我遇到问题的输出：
这是我加载此数据网格的方法：
public static void LoadAllEventsForHomeTeam(System.Windows.Controls.ComboBox cb,System.Windows.Controls.DataGrid dg)
{
var url = new Url("http://worldcup.sfg.io/matches/country?fifa_code=");
string urlEndpoint = GetItemFromComboBoxWpf(cb);
var request = url + urlEndpoint;
string cbItem = cb.SelectedItem.ToString();
System.Windows.Controls.DataGridTextColumn c1 = new System.Windows.Controls.DataGridTextColumn();
c1.Header = "Game ID";
c1.Binding = new System.Windows.Data.Binding("FifaID");
c1.Width = 120;
dg.Columns.Add(c1);
System.Windows.Controls.DataGridTextColumn c2 = new System.Windows.Controls.DataGridTextColumn();
c2.Header = "City";
c2.Binding = new System.Windows.Data.Binding("Venue");
c2.Width = 95;
dg.Columns.Add(c2);
System.Windows.Controls.DataGridTextColumn c3 = new System.Windows.Controls.DataGridTextColumn();
c3.Header = "Location";
c3.Binding = new System.Windows.Data.Binding("Location");
c3.Width = 150;
dg.Columns.Add(c3);
System.Windows.Controls.DataGridTextColumn c4 = new System.Windows.Controls.DataGridTextColumn();
c4.Header = "Date";
c4.Binding = new System.Windows.Data.Binding("Date");
c4.Width = 180;
dg.Columns.Add(c4);
System.Windows.Controls.DataGridTextColumn c5 = new System.Windows.Controls.DataGridTextColumn();
c5.Header = "Goals";
c5.Binding = new System.Windows.Data.Binding("Goals");
c5.Width = 75;
dg.Columns.Add(c5);
System.Windows.Controls.DataGridTextColumn c6 = new System.Windows.Controls.DataGridTextColumn();
c6.Header = "Penalties";
c6.Binding = new System.Windows.Data.Binding("Penalties");
c6.Width = 100;
dg.Columns.Add(c6);
System.Windows.Controls.DataGridTextColumn c7 = new System.Windows.Controls.DataGridTextColumn();
c7.Header = "Guest";
c7.Binding = new System.Windows.Data.Binding("AwayTeamCode");
c7.Width = 90;
dg.Columns.Add(c7);
System.Windows.Controls.DataGridTextColumn c8 = new System.Windows.Controls.DataGridTextColumn();
c8.Header = "Guest score";
c8.Binding = new System.Windows.Data.Binding("GuestGoals");
c8.Width = 110;
dg.Columns.Add(c8);
System.Windows.Controls.DataGridComboBoxColumn c9 = new System.Windows.Controls.DataGridComboBoxColumn();
c9.Header = "Team 11";
c9.TextBinding = new System.Windows.Data.Binding("HomeTeam11");
c9.Width = 110;
dg.Columns.Add(c9);
try
{
dispatcher.Currentdispatcher.BeginInvoke(new Action(async () =>
// await Task.Run(async () =>
{
if (request != null)
{
List<Teams.RootObject> matches = await request.GetJsonAsync<List<Teams.RootObject>>();
foreach (var match in matches)
{
if (cbItem.Contains(match.home_team.code))
{
dg.Items.Add(new Teams.DGObject
{
FifaID = match.fifa_id,Venue = match.venue,Location = match.location,Date = match.datetime.ToLocalTime(),Goals = match.home_team.goals,Penalties = match.home_team.penalties,AwayTeamCode = match.away_team.code,GuestGoals = match.away_team.goals,HomeTeam11 = match.home_team_statistics.starting_eleven
});
}
}
}
}));
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
如您所见，此方法将数据网格加载为所选球队的足球比赛事件。通过从组合框中选择一个项目，这里命名为 cb，一个方法通过完成一个 API 调用来形成一个 API 调用，选择组合框项目作为端点，从而加载数据网格，其中包含德国作为主队参加的比赛。现在，问题来了：最后一列，此处命名为 Team11 应包含组合框，组合框应包含参加该比赛的 11 名球员（起始 11 名）。被选中的球队，在这种情况下，德国显然作为主队打了四场比赛。因此，在 Team11 列中应该有四个组合框，每场比赛一个，放置在每一行，每个组合框应包含参加该特定比赛的 11 名球员，但 Team11 列中没有数据。有任何想法吗？谢谢。
