[WPF][C#][Study] DataGrid 컨트롤

DataGrid 컨트롤

- ListView와 비슷하지만 추가기능 제공(데이터에 따라 열 자동 생성, 편집 가능)

 

[예제 1]

- DataGrid 기본 형태

1) xaml

<Window x:Class="WpfTutorialSamples.DataGrid_control.SimpleDataGridSample"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="SimpleDataGridSample" Height="180" Width="300">
    <Grid Margin="10">
        <DataGrid Name="dgSimple"></DataGrid>
    </Grid>
</Window>

2) code-behind

using System;
using System.Collections.Generic;
using System.Windows;

namespace WpfTutorialSamples.DataGrid_control
{
    public partial class SimpleDataGridSample : Window
    {
        public SimpleDataGridSample()
        {
            InitializeComponent();

            List<User> users = new List<User>();
            users.Add(new User() { Id = 1, Name = "John Doe", Birthday = new DateTime(1971, 7, 23) });
            users.Add(new User() { Id = 2, Name = "Jane Doe", Birthday = new DateTime(1974, 1, 17) });
            users.Add(new User() { Id = 3, Name = "Sammy Doe", Birthday = new DateTime(1991, 9, 2) });

            dgSimple.ItemsSource = users;
        }
    }

    public class User
    {
        public int Id { get; set; }

        public string Name { get; set; }

        public DateTime Birthday { get; set; }
    }
}

[예제 2]

- 열 직접 정의

- 다양한 유형들을 기준으로 사용할 수 있음

- DataGridTextColumn : 문자

- DataGridCheckBoxColumn : 체크박스

- DataGridComboBoxColumn : 콤보박스

- DataGridHyperlinkColumn : 하이퍼링크

- DataGridTemplateColumn : 템플릿

1) xaml

<Window x:Class="WpfTutorialSamples.DataGrid_control.DataGridColumnsSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="DataGridColumnsSample" Height="200" Width="300">
    <Grid Margin="10">
    	<!--AutoGenerateColumns을 false로 하여 직접 열을 정의할 수 있음-->
		<DataGrid Name="dgUsers" AutoGenerateColumns="False">
        
			<DataGrid.Columns>
            
            	<!--1.문자 열-->
				<DataGridTextColumn Header="Name" Binding="{Binding Name}" />
                <!--2.템플릿 열-->
				<DataGridTemplateColumn Header="Birthday">
					<DataGridTemplateColumn.CellTemplate>
						<DataTemplate>
							<DatePicker SelectedDate="{Binding Birthday}" BorderThickness="0" />
						</DataTemplate>
					</DataGridTemplateColumn.CellTemplate>
				</DataGridTemplateColumn>
                
			</DataGrid.Columns>
		</DataGrid>
	</Grid>
</Window>

2) code-behind

using System;
using System.Collections.Generic;
using System.Windows;

namespace WpfTutorialSamples.DataGrid_control
{
	public partial class DataGridColumnsSample : Window
	{
		public DataGridColumnsSample()
		{
			InitializeComponent();

			List<User> users = new List<User>();
			users.Add(new User() { Id = 1, Name = "John Doe", Birthday = new DateTime(1971, 7, 23) });
			users.Add(new User() { Id = 2, Name = "Jane Doe", Birthday = new DateTime(1974, 1, 17) });
			users.Add(new User() { Id = 3, Name = "Sammy Doe", Birthday = new DateTime(1991, 9, 2) });

			dgUsers.ItemsSource = users;
		}
	}

	public class User
	{
		public int Id { get; set; }

		public string Name { get; set; }

		public DateTime Birthday { get; set; }
	}
}

3) 결과

- 첫번째 열은 문자로, 두번째 탭은 템플릿을 만들어 해당 템플릿의 형태로 열을 구성하였다.

 

[예제 3]

- RowDetailsTemplate

- 행(row) 세부정보 표시

1) xaml

<Window x:Class="WpfTutorialSamples.DataGrid_control.DataGridDetailsSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="DataGridDetailsSample" Height="200" Width="400">
        
	<Grid Margin="10">
		<DataGrid Name="dgUsers" AutoGenerateColumns="False">
        
			<DataGrid.Columns>
				<DataGridTextColumn Header="Name" Binding="{Binding Name}" />
				<DataGridTextColumn Header="Birthday" Binding="{Binding Birthday}" />
			</DataGrid.Columns>
            
			<DataGrid.RowDetailsTemplate>
				<DataTemplate>
					<TextBlock Text="{Binding Details}" Margin="10" />
				</DataTemplate>
			</DataGrid.RowDetailsTemplate>
            
		</DataGrid>
	</Grid>
</Window>

2) code-behind

using System;
using System.Collections.Generic;
using System.Windows;

namespace WpfTutorialSamples.DataGrid_control

	public partial class DataGridDetailsSample : Window
	{
		public DataGridDetailsSample()

			users.Add(new User() { Id = 3, Name = "Sammy Doe", Birthday = new DateTime(1991, 9, 2) });

			dgUsers.ItemsSource = users;
		}
	}

	public class User
	{
		public int Id { get; set; }

		public string Name { get; set; }

		public DateTime Birthday { get; set; }

		public string Details
		{
			get
			{
				return String.Format("{0} was born on {1} and this is a long description of the person.", this.Name, this.Birthday.ToLongDateString());
