WPF - 数据网格

DataGrid 是一种以可自定义网格显示数据的控件。它提供了一种灵活的方式，可以以行和列的形式显示数据集合。DataGrid 类的层次继承如下：

示例

• 让我们创建一个名为 WPFDataGridControl 的新 WPF 项目。

• 从工具箱中拖动数据网格。

• 以下示例演示如何在 DataGrid 中显示数据。下面是创建了两个数据网格以及一组属性和事件的 XAML 代码。

<Window x:Class = "WPFDataGridControl.MainWindow"
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" 
   xmlns:core = "clr-namespace:System;assembly = mscorlib" 
   xmlns:local = "clr-namespace:WPFDataGridControl" 
   Title = "MainWindow" Height = "350" Width = "525"> 
	
   <Window.Resources>
      <ObjectDataProvider x:Key = "myEnum" MethodName = "GetValues" 
         ObjectType = "{x:Type core:Enum}"> 
			
         <ObjectDataProvider.MethodParameters> 
            <x:TypeExtension Type = "local:Party" /> 
         </ObjectDataProvider.MethodParameters>
			
      </ObjectDataProvider> 
   </Window.Resources>
	
   <Grid> 
      <DataGrid Name = "dataGrid" AlternatingRowBackground = "LightBlue"  
         AlternationCount = "2" AutoGenerateColumns = "False"> 
			
         <DataGrid.Columns> 
            <DataGridTextColumn Header = "Name" Binding = "{Binding Name}" /> 
            <DataGridTextColumn Header = "Title" Binding = "{Binding Title}" /> 
            <DataGridCheckBoxColumn Header = "ReElected?" Binding = "{Binding WasReElected}"/> 
            <DataGridComboBoxColumn Header = "Party" SelectedItemBinding = "{Binding Affiliation}" 
               ItemsSource = "{Binding Source = {StaticResource myEnum}}" /> 
         </DataGrid.Columns> 
			
      </DataGrid> 
   </Grid> 
	
</Window>

以下是C# 实现，用于两个不同的类。

using System.Linq; 
using System.Text; 
using System.Threading.Tasks;

namespace WPFDataGridControl { 
   /// <summary>
      /// Interaction logic for MainWindow.xaml 
   /// </summary>
	
   public partial class MainWindow : Window { 
	
      public MainWindow() { 
         InitializeComponent(); 
         dataGrid.ItemsSource = Employee.GetEmployees(); 
      } 
   } 
	
   public enum Party { 
      Indepentent, 
      Federalist, 
      DemocratRepublican, 
   }
	
   public class Employee : INotifyPropertyChanged { 
      private string name;
	
      public string Name { 
         get { return name; } 
         set { 
            name = value; 
            RaiseProperChanged(); 
         } 
      } 
	
      private string title; 
	
      public string Title { 
         get { return title; } 
         set { 
            title = value; 
            RaiseProperChanged(); 
         } 
      }  
	
      private bool wasReElected; 
	
      public bool WasReElected { 
         get { return wasReElected; } 
         set { 
            wasReElected = value; 
            RaiseProperChanged(); 
         } 
      }  
	
      private Party affiliation;
	
      public Party Affiliation { 
         get { return affiliation; } 
         set { 
            affiliation = value; 
            RaiseProperChanged(); 
         }
      }  
	
      public static ObservableCollection<Employee> GetEmployees() { 
         var employees = new ObservableCollection<Employee>();
			
         employees.Add(new Employee() { Name = "Ali", Title = "Minister", WasReElected = true,
            Affiliation = Party.Indepentent });
			
         employees.Add(new Employee() { Name = "Ahmed", Title = "CM", WasReElected = false,
            Affiliation = Party.Federalist }); 
			
         employees.Add(new Employee() { Name = "Amjad", Title = "PM", WasReElected = true, 
            Affiliation = Party.DemocratRepublican });
			
         employees.Add(new Employee() { Name = "Waqas", Title = "Minister",
            WasReElected = false, Affiliation = Party.Indepentent }); 
			
         employees.Add(new Employee() { Name = "Bilal", Title = "Minister",
            WasReElected = true, Affiliation = Party.Federalist }); 
			
         employees.Add(new Employee() { Name = "Waqar", Title = "Minister",
            WasReElected = false, Affiliation = Party.DemocratRepublican }); 
			
         return employees; 
      }  
	
      public event PropertyChangedEventHandler PropertyChanged; 
	
      private void RaiseProperChanged([CallerMemberName] string caller = "") { 
	
         if (PropertyChanged != null) { 
            PropertyChanged(this, new PropertyChangedEventArgs(caller)); 
         } 
      } 
	
   } 
	
}

编译并执行上述代码后，将生成以下窗口。

我们建议您执行上述示例代码，并尝试 DataGrid 的其他一些属性和事件。
