WPF DataGrid - 我可以用属性来装饰我的 POCO 以获得自定义列名吗? [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 并用这样的数据填充它:
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;
}
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 ComboCox 上显示它们(而不是变量名称).
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.
像这样:
public enum Sharing
{
[Name("This is a test")]
Equal,
[Name("This is a test 2")]
SurfaceBased,
}
这可能吗?
推荐答案
好的.这是为标题执行此操作的方法:
OK. Here is the way to do it for the Headers:
您向属性添加属性,例如 Description
属性.
You add attributes, like Description
attributes to your Properties.
public class MyPOCO
{
[Description("The amount you must pay")]
public float Amount { get; set; }
}
然后,在从 DataGrid 派生的类中,您执行以下操作:
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);
}
}
要为枚举成员添加自定义名称,您需要创建一个自定义列.你可以在这里看到一个简单的例子:https://stackoverflow.com/a/17510660/964053.
For adding custom names to the members of the enumerations, you need to make a custom column. You can see a simple example here : https://stackoverflow.com/a/17510660/964053.
