数据绑定到DevExpress XtraGrid的问题

问题描述

我有一个XtraGrid掉到了Winform。我创建了3个未绑定的列，名为ID，StartTime和EndTime，并将其未绑定的类型分别设置为Int，DateTime和DateTime。
我创建了一个类：

---

  public class Data 
 {
 public Data（int id，DateTime startTime，DateTime endTime）
 {
 this.id = id; 
 this.startTime = startTime; 
 this.endTime = endTime; 
} 
 private int id; 
 private DateTime startTime; 
 private DateTime endTime; 
 public int ID 
 {
 get {return id; } 
 set {id = value; } 
} 
 public DateTime StartTime 
 {
 get {return startTime; } 
 set {startTime = value; } 
} 
 public DateTime EndTime 
 {
 get {return endTime; } 
 set {endTime = value; } 
} 
} 
  

在表单构造函数中，我创建了一个列表并绑定列表到我的网格控制运行时

 列表<数据> list = new List< Data>（）; 
 list.AddRange（new Data [] {
 new Data（1，Convert.ToDateTime（1:00:00 AM），
 Convert.ToDateTime（3:00:00 AM）），
 new Data（2，Convert.ToDateTime（8:00:00 PM），
 Convert.ToDateTime（8:30:00 PM）），
 new Data（3，Convert.ToDateTime（12:00:00 PM），
 Convert.ToDateTime（1:00:00 AM）），
 new Data（4，Convert。 ToDateTime（2:00:00 AM），
 Convert.ToDateTime（3:00:00 AM））
}）; 
 gridControl1.DataSource = list; 
  

运行应用程序时，我得到一个空格。不知何故，我在设计时创建的列在运行时没有与数据正确填充。我尝试做同样的事情，没有在设计时创建的列，应用程序运行与正确填充的数据。我错过了一些东西

解决方案

将列的FieldName属性设置为ID，StartTime，EndTime案件敏感!!!!）。此外，我建议您移动代码将网格的DataSource设置为窗体的Load事件。这应该可以帮助你。

I have a XtraGrid dropped on to a Winform. I have created 3 unbound columns named ID, StartTime and EndTime and set their unbound types as Int, DateTime and DateTime respectively.I have created a class:

---

public class Data
{
    public Data(int id, DateTime startTime, DateTime endTime)
    {
        this.id = id;
        this.startTime = startTime;
        this.endTime = endTime;
    }
    private int id;
    private DateTime startTime;
    private DateTime endTime;
    public int ID
    {
        get { return id; }
        set { id = value; }
    }
    public DateTime StartTime
    {
        get { return startTime; }
        set { startTime = value; }
    }
    public DateTime EndTime
    {
        get { return endTime; }
        set { endTime = value; }
    }
}

In the form constructor I created a List and bind the list to my gridcontrol at runtime

        List<Data> list = new List<Data>();
        list.AddRange(new Data[] {
                    new Data(1, Convert.ToDateTime("1:00:00 AM"),
                    Convert.ToDateTime("3:00:00 AM")),
                    new Data(2, Convert.ToDateTime("8:00:00 PM"),
                    Convert.ToDateTime("8:30:00 PM")),
                    new Data(3, Convert.ToDateTime("12:00:00 PM"),
                    Convert.ToDateTime("1:00:00 AM")),
                    new Data(4, Convert.ToDateTime("2:00:00 AM"),
                    Convert.ToDateTime("3:00:00 AM"))
                    });
        gridControl1.DataSource = list;

When run the application, I get an empty grid. Somehow the columns that I created at design time are not filled correctly with the data at runtime. I try to do the same thing with no columns created at design time and the application run with correctly filled data. I am missing something.

解决方案

Set the FieldName property of your columns to ID, StartTime, EndTime (Case Sensitively!!!!). Also, I would suggest that you move your code to set the grid's DataSource to the form's Load event. This should help you.
