WPF DataGrid - 我可以使用属性来装饰我的POCO以具有自定义列名吗？ [英] WPF DataGrid - Can I decorate my POCOs with attributes to have custom column names?

问题描述

我在WPF中有一个DataGrid，并填写如下数据：

  public enum Sharing 
 {
等于
 SurfaceBased，
} 
 
 public class Data 
 {
 public bool Active {get;组; } 
 public string Name {get;组; } 
 public int Floor {get;组; } 
 public Sharing Sharing {get;组; } 
} 
 public ObservableCollection< Data> _col = new ObservableCollection< Data>（）
 {
 new Data（）{Active = true，Name =KRL，Floor = 0}，
 new Data（）{Name = DAT，Floor = 1}，
 new Data（）{Name =TRE，Floor = 1}，
 new Data（）{Name =DUO，Floor = 2}，
}; 
 
 public MainWindow（）
 {
 InitializeComponent（）; 
 
 grid.AutoGenerateColumns = true; 
 grid.DataContext = _col; 
 grid.ItemsSource = _col; 
} 
  

我想知道是否可以在枚举和POCO类上使用一些属性以便DataGrid在标题和ComboCoxes上显示它们（而不是变量名）。

这样的一个例子：

  public enum Sharing 
 {
 [Name（This is a test）] 
等于
 [Name（This是一个测试2）] 
 SurfaceBased，
} 
  

？

解决方案

可以。这是为标题执行的方法：

您可以向属性添加属性，例如描述属性。

  public class MyPOCO 
 {
 [说明（您必须支付的金额）] 
 public float Amount {get;组; } 
} 
  

然后，在从DataGrid派生的类中，您可以执行以下操作：

  protected override void OnAutoGeneratingColumn（DataGridAutoGeneratingColumnEventArgs e）
 {
 try 
 {
 base。 OnAutoGeneratingColumn（e）; 
 var propDescr = e.PropertyDescriptor as System.ComponentModel.PropertyDescriptor; 
 e.Column.Header = propDescr.Description; 
} 
 catch（Exception ex）
 {
 Utils.ReportException（ex）; 
} 
} 
  

要向枚举成员添加自定义名称，您需要自定义列。您可以在这里看到一个简单的例子： http://stackoverflow.com/a/17510660/964053 。

I have a DataGrid in WPF and fill it with data like this:

public enum Sharing
{
    Equal,
    SurfaceBased,
}

public class Data
{
    public bool Active { get; set; }
    public string Name { get; set; }
    public int Floor { get; set; }
    public Sharing Sharing { get; set; }
}
    public ObservableCollection<Data> _col = new ObservableCollection<Data>()
                                 {
                                  new Data(){Active = true, Name = "KRL", Floor = 0 },
                                  new Data(){Name = "DAT", Floor = 1},
                                  new Data(){Name = "TRE", Floor = 1},
                                  new Data(){Name = "DUO", Floor = 2},
                                 };

    public MainWindow()
    {
        InitializeComponent();

        grid.AutoGenerateColumns = true;
        grid.DataContext = _col;
        grid.ItemsSource = _col;
    }

I was wondering if I could use some attributes on the enumerations and the POCO class so that the DataGrid displays them (instead of the variable names) on the headers and ComboCoxes.

Something like this:

public enum Sharing
{
    [Name("This is a test")]
    Equal,
    [Name("This is a test 2")]
    SurfaceBased,
}

Is this possible?

解决方案

OK. Here is the way to do it for the Headers:

You add attributes, like Description attributes to your Properties.

public class MyPOCO
{
    [Description("The amount you must pay")]
    public float Amount { get; set; }
}

Then, in a class derived from DataGrid you do this:

    protected override void OnAutoGeneratingColumn(DataGridAutoGeneratingColumnEventArgs e)
    {
        try
        {
            base.OnAutoGeneratingColumn(e);
            var propDescr = e.PropertyDescriptor as System.ComponentModel.PropertyDescriptor;
            e.Column.Header = propDescr.Description;
        }
        catch (Exception ex)
        {
            Utils.ReportException(ex);
        }
    }

For adding custom names to the members of the enumerations, you need to make a custom column. You can see a simple example here : http://stackoverflow.com/a/17510660/964053.
