C#(WPF) - Datagrid 멀티라인 추가하기

아래와 같이 xaml에서 직접 작성할 수 있습니다.

<?xml version="1.0" encoding="utf-8"?>

아래와 같이 C#코드로 작성할 수도 있습니다.

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;

namespace ebar
{
	/// <summary>
	/// Interaction logic for Window1.xaml
	/// </summary>
	public partial class Window1 : Window
	{
		public Window1()
		{
			InitializeComponent();
			
			DataGridTextColumn textColumn = new DataGridTextColumn();
			textColumn.Header = "Column 1";
			textColumn.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
			textColumn.HeaderTemplate = new DataTemplate();
			
			FrameworkElementFactory stackPanel = new FrameworkElementFactory(typeof(StackPanel));
			stackPanel.SetValue(StackPanel.OrientationProperty, Orientation.Vertical);
			
			FrameworkElementFactory firstLine = new FrameworkElementFactory(typeof(TextBlock));
			firstLine.SetValue(TextBlock.TextProperty, "First line");
			firstLine.SetValue(TextBlock.FontSizeProperty, 16d);
			firstLine.SetValue(TextBlock.FontWeightProperty, FontWeights.Bold);
			
			FrameworkElementFactory secondLine = new FrameworkElementFactory(typeof(TextBlock));
			secondLine.SetValue(TextBlock.TextProperty, "Second line");
			secondLine.SetValue(TextBlock.FontSizeProperty, 12d);
			secondLine.SetValue(TextBlock.FontStyleProperty, FontStyles.Italic);
			
			stackPanel.AppendChild(firstLine);
			stackPanel.AppendChild(secondLine);
			
			textColumn.HeaderTemplate.VisualTree = stackPanel;
			
			worktable.Columns.Add(textColumn);		
		}
	}
}

 

이 경우 XAML코드에서 필요없는 Column정의부분은 지워도 무관합니다.
